DMA and default iOS browsers

In light of DMA developments, I hear that Apple not following “the spirit” of the law and doesn’t allow competition in the App Store marketplace. According to the regulators, being the sole distributor of the entire market, Apple doesn’t allow competition. As an indie developer, I couldn’t care less about outside App Store distribution. And as a full-time contractor for a big company, I don’t see how adding additional distribution channels outside of the App Store, will help my team deliver better user experience.…

iPhone upgrade

My first experience picking up a refurbished iPhone 13 mini from Amazon UK. There’s no central “Amazon” refurbished hub, and any phone you get is a surprise because Amazon works with multiple partners. Some of them had original cables, and some of them had non-original cables. Battery health was not 100% and was below 90%, with micro scratches on the screen. The price for the 512 GB model was a lesser jump than what you usually get when buying a new iPhone.…

iOS keyboard bug. Combination of a long password and home button leads to invisible keyboard. Appears consistently after every reboot. First noticed in iOS 16, appears still in 17.5 FB11901083

Quick update, upgraded SE 2nd generation to iPhone 13 mini. This is the first selfie I made. I like the size so much. Battery life is not great, but compared to my iPhone SE it is plenty. I am still in a habit of conserving battery life. This’s been a difficult week, can’t wait until next weekend.

UWB chip in iPhone 11

Apple has started including Ultra Wideband chips in iPhone 11. There were zero iOS features at that time, except, AirDrop interface improvements.

Watched the Civil War two days ago, it was a thrilling emotional ride. A film about war photography. We watched it at Curzon in Victoria (London). The screen (screen 5) was not huge it had nice seats and the sound was separated. The screen didn’t feel small. It worked great in the cinema because the picture took the entire canvas.

A bit earlier this week we also watched Oscar winner 20 Days in Mariupol at home. Be warned it has footage of dead babies killed by Russian invaders. Picture quality is not good for obvious reasons, but you shouldn’t worry about these things while watching real war footage unfolding.

I’m introducing my kids to Patapon remasters. Sadly Patapon and Loco Roco developers were laid off in April 2021. I had great memories playing both on the original PSP. If you worked on any of these amazing games, thank you. Japan Studio, you are legends.

Word of caution on Sonoma 14.3.1 using the save command on PDF form using new AI features in Apple Preview erases my edits. Ironically just closing a window works as expected and content is not lost. I reproduced this bug on 2 Macs already.

I realised that custom or overcomplicated user interfaces irritate me even more over longer periods. I have little energy when doing repetitive tasks daily on my iPhone and Mac, I don’t enjoy interacting with one-of-a-kind interfaces.

Had a long and frustrating experience using my iPhone. The keyboard was especially slow. I knew something was odd and was blaming old hardware instead of realising it was a dream.

I can’t be 100% sure but I think I just lost my 2FA after doing iCloud Keychain import from 1Password. I had the same password in both places but 2FA existed only in iCloud Keychain. Lessons learned — only import passwords into an empty keychain.

This week there’s an interesting interview with Mark Zuckerberg defending the Meta Quest. I welcome the competition. Android was a tremendous factor in pushing Apple to make the iPhone better. I am convinced that investment behind the Apple Silicone is partially possible due to competition from Google and Samsung. Apple’s custom processors are a big win for iPhone consumers. I am hopeful that Meta products will push Apple to work harder.

From my podcast feed, two close friends recorded a podcast while wearing Apple Vision Pro headsets. Listen to The Talk Show with Adam Lisagor. If you are optimistic and excited about Apple Vision Pro, you will enjoy this episode. In short, the episode reassured me once more that Apple made the right choice by shipping this device in 2024. John mentioned that he was eager for more people to get the headset so they could experience what he experienced. And they talk about powerful feelings and excitement almost reaching the level of the original iPhone debute.

The App Store EU regulations

Okay, it is unlikely anyone will read this blog, and it is even less likely you will read it on 26 January 2024. But if you do, you are likely to know about yesterday’s changes from EU lawmakers. These changes flooded my NetNewsWire feed and made me want to drink heavily last night. The reaction from the indie dev community is, to be blunt, not fruitful. There’s two things to unwrap here, first my disappointment with the third-party dev community public reaction, and second my own opinion on how these changes should be seen — not as a decease symptom but rather ripples on a pond.…

Xcode entitlement fallout

Is Apple going to demand a 30% cut on future macOS releases? It’s not going to happen because the Mac is a PC device, and iPhone, iPad and Apple Vision Pro are post-PC devices.

Big news for iOS developers.

If a developer wants users to sign up and pay on their website, they can now tell them so, in plain language, in the app.

Update. Apple posted some impressively detailed guidelines. New API is US only and they take 12% / 27% commissions. Apple is not happy with this outcome. I’m curious how popular this API is going to be.

Listening to the first impressions my conclusion this product doesn’t deliver on its promises and likely will never be able to.

Experience creating an Instagram account in 2024. I waited 5-10 minutes on this onboarding step which was building friend recommendations for me based on my Facebook social graph. It never stopped, had to kill the app. Luckily app recovered and I was presented with a next step.

Created a new Instagram account for myself, using Facebook ID. I need it to keep in touch with younger generations of friends and family. I will experiment with Threads, also for close friends and family. Will continue to follow tech people here.…

My high score was 644.

I am not going to buy Apple Vision Pro just yet. But I’m very excited for the people who will. For me, it’s the most interesting and important topic in tech in 2024, and possibly many many years forward.

Let’s go back to the good times when you could buy your software once and own it. I like this manifest — goes without saying, that none of my apps will require a subscription, neither future projects ever will.

Monitoring key window in SwiftUI on a Mac

My Mac app can run in multiple windows and every window can have multiple tabs AKA “window tabs”. We don’t need to do any development work to support tabs in our Mac apps. Sadly I had to disable window tabs in my SwiftUI project because macOS doesn’t tell me when a user switches tabs. I use @Environment(\.controlActiveState) to monitor when a user switches between multiple windows. It’s a well-known approach and there are many blog posts describing this technique.…

Pero's origin story

I have been frustrated with 1Password for Apple Watch. The app has a launch delay, and sometimes it won’t load at all, showing an empty screen. Our household was paying a $59.85 subscription for 5 years.1 This means we invested around $300 in subscription costs. I find it unacceptable. Naturally, I found a solution by building a brand new password manager. When we worked on Pero, we had only one goal — to make the interface as fast as possible while delivering a powerful and useful tool.…

Alex Guyot of MacStories, watchOS 10 review

I’ve been using watchOS 10 since August, and I love using Smart Stack whenever I need it. It is always pleasant and fast. It’s my favourite way to check the weather and upcoming calendar events.

Upgraded to the new home architecture, had to re-enable ARC on Apple TV 4K. Also did set up my Hue light with Matter. This now requires creating a Philips account. Bad move from Philips, as they clearly just want my email address, and technically account is not required for Matter to work.

Just finised playing The Quarry last night. It’s the best couch co-op you can play with another adult. We had lots of fun and achieved multiple endings. It’s hard to keep everyone alive but the game is friendly to non-gamers and teaches you everything you have to do as part of the story. I love how almost real facial expressions look like in this game, the difference is almost as big as Half-Life 2 and everything that came before.…

Chorizo and spinach paella

Good inexpensive and filling dish, easy to cook and very tasty. You can add prawn or seafood if you fancy but it is great with just chorizo, and you need just a little bit. I have found it on Tesco’s website and cooked it twice already. The ingredients were easy to find in any shop in the UK, in my case it was Morrisons. Download the PDF as a backup in case page goes down.…

Working with file system on macOS

In my spare time, I continue to practice with AppKit and SwiftUI for macOS. My current goal is to subscribe to changes in a folder with text documents and other nested folders. Current version of LinkEdit uses small library called FileWatcher, which relies on File System Events. One issue with File System Events is they only work on the Mac and the API is hard to understand because it’s a low-level API.…

PS5 first impressions

There are PS5 ads everywhere in London and it’s available for sale. I can’t believe it’s been 2 years since the launch, it feels like yesterday. I have sold a bunch of old techs and accumulated around £250 worth of vouchers. Even sold my old 5G router for a whopping £100, didn’t know it has so much value. I couldn’t resist buying a used PS5. Don’t do that, Cex still charges more than Sony which is a crime for a used console, even in perfect condition.…

From a developer perspective, I am most interested in SwiftUI improvements, file system handling, TextEditor view and more AppKit features available in SwiftUI.

I began the slow process of switching from 1Password to iCloud Keychain, for now, the most thing I miss is being able to change the URL and add multiple addresses. I am most interested in iCloud Keychain improvements this WWDC, and I am optimistic.

iOS 16.4 Beta 2 Re-Adds Page Turning Animation to Apple Books – MacRumors. 👏🏻👏🏻👏🏻

I wish Sony learns UX from Nintendo, Switch has a much better interface than PS5, except for low resolution. 🎮

Today’s dinner. Added some protein (egg and sausage) and some greens, and spent 5 minutes fryings. The results are great. I try to have this as a last resort because everything is wrapped in plastic. Purchased in large Waitrose.

Ukraine-related disinformation on YouTube

I stumbled upon a video on YouTube which starts with the host blaming Ukranian soldiers for using chemical weapons (cyanide). 2 people are speaking for a long time, the host and an ex-military adviser who is likely not aware that he is been fooled or purposefully lying. The video shows brief footage stitched together with sounds removed. They conveniently don’t link to the original source. There’s nothing in the source video which suggests the use of chemicals, it shows some explosive charges and a powered-off fridge.…

What's the deal with HomePod

I’ve been always interested in home audio equipment, tinkering with sound since high school, and pursuing the best possible quality while staying on budget. Usually, I just used whatever we had at home. My first home theatre is a 5.1 Sven audio system combined with an external TV tuner and SoundBlaster audio card. The amount of time I spent connecting the wires, and playing with the drivers and DVD player apps was tremendous.…

Did some wiring for my Apple TV. There are these amazing flat ethernet cables which are easy to hide in between wall and carpet.

HomePod grows

I replaced a pair of HomePod minis1 with the new full-size model today. Returning from school, my son joked that “HomePod is growing” and he noticed the fresh scent and smelled it. With no pun intended, I think HomePod has indeed grown and I am excited about the purchase, it’s the right product for me. It’s final peace to fulfilling my long-lasting dream of building a Hi-Fi system for the entire home and also solving many little annoyances I had.…

Touch screen Macs

Listened to the latest Connected. I love my M1 Max MacBook Pro 16 as my only computer right now. Would it be great to have something as powerful with a removable touchscreen display? Probably yes. But at this point, it feels like a mirage. I feel like we will get there eventually, just not yet. The tech has to be great, it should not feel clunky. thinks way ahead of the curve.…

Half-Life Mac ports

Today I had a thought, wouldn’t be nice to play the original Half-Life on Mac again? Once a year I open Steam with the hope that Valve releases 64-bit support for their greatest titles. But no. Turns out, some good people reverse-engineered the 32-bit engine, and then Mac Source Ports owner rewrote it for the 64-bit architecture and released the signed native build for Apple Silicon Macs! I played through the tutorial, and it still surprised me, I forgot that the game has physics-based puzzles.…

Finally, Germany has agreed to send tanks to Ukraine. Hopefully, it won’t take a long time.

I never liked Twitter threads, they always felt like a hack to me. has a much better approach by allowing both short and expandable posts.

Nvidia released a “new” Eye Contact feature. 1.8K comments on Reddit, no one there even knows that Apple shipped this feature in FaceTime 2 years ago.

Listen to the latest episode of The Talk Show about the early years of Twitter and collaborations with the Twitterrific app. Did you know that the bird icon and the word “tweet” came not from Twitter but from The Iconfactory?

Rediscovered the Feedback section in the App Store Connect with screenshots from TestFlight users. It doesn’t notify you about new messages. I will have to check it regularly.

If you were thinking about buying a HomePod mini in the UK, you still can get one from Argos with the old price £90. It’s now selling for £100 everywhere else. I ordered 2, just for the humidity and temperature sensors alone.

I want to watch The Last of Us, but in the UK it’s on Sky’s NOW TV app, and it feels like it has the lowest fidelity among all streaming apps, will probably have to wait for the iTunes release. 📺

It took 1 month and 5 days of my free evening time to ship this update. I am relieved and a bit terrified because it includes business model transition, data model upgrade and WidgetKit migration. Contains 58 commits.

2 HomePod speakers ordered

Having great memories of watching LOTR, The Shining, Lisey’s Story and The Witcher and then reading original books. Because originals are better, it allows me to enjoy both. Planning to do the same for The Last of Us HBO show.

Today I replaced the battery in my iPhone SE, it cost £49. I am going back to 2nd gen iPhone SE from iPhone 13. I have missed smaller size and weight, even typing feels better. Going to enjoy playing Vampire Survivors without feeling hand fatigue. I do like having top and bottom bezels again, they might not look as sexy but protect from accidental input when watching a video in landscape or even when just holding the device I can trigger a tab bar press with the edges of my palm. The only things I am going to miss are the camera and MagSafe.

Some nerdy stats:

Seville orange & Sichuan pepper crispy tofu

Last night’s dinner was a disaster. I wanted to share this because failure is equally important to success. Even though this is a receipt from Waitrose, Sichuan pepper and sriracha for the sauce couldn’t be found. Tofu was cut too small. Tofu was kept in the oven which made them dry, even though the oven was switched off. Tofu bites needed to be turned half-through. The receipt has 250g brown sugar, which is a lot, it’s not for everyone.…

My strategy of fetching HealthKit from the WidgetKit extension is not working, especially when used for Apple Watch complications. Frustratingly, using deprecated complications API has fewer issues, but it’s more efficient to do the job in the app target.

Knives Out and its poor sequel

When someone at Netflix with good taste realised that Knives Out is a great film, they purchased the rights and paid for the sequel. Glass Onion remains entertaining but lesser than the original. I recommend you start with the sequel, you won’t miss a thing plot-wise. The original is better, you will finish watching on a high note with greater satisfaction. There are many things in Glass Onion I find annoying, boring and uninspiring.…

My first attempt to try something from Waitrose Food magazine (free with their membership card). This dish is healthy and easy to make. I got 4 portions which covered 2 dinners.

After half a year without Always On display on my watch, I now enabled it again. It happened after I reflected that I was annoyed on many occasions. But it didn’t happen instantly, it’s more like annoyance which grew until the tipping point.

I have tried to use Dual USB-C port to drive our 2 HomePod minis which we use as TV speakers but it doesn’t provide enough power.

Vampire Survivors

You should try Vampire Survivors for iOS. I only played once and I know I’m going to love it. I don’t understand why this game is free. It’s one of the most popular titles for Steam Deck, and it costs £3.99 on Steam. IAP/ads are likely going to appear once the iOS port is popular. Disabled App Store updates to save this gem. This is the first time in my life I see such a good product, free, with no ads and offline play.…

Comparing wardrobes

We needed a wardrobe and we decided to buy it from John Lewis instead of IKEA which would be a usual choice. I have assembled IKEA’s PAX system twice. The wardrobe from John Lewis is much smaller, it took me less than 6 hours to build it. During labouring I appreciated many details, I don’t think IKEA is going to be our default choice in the future. So what’s different?…

Mastodon users celebrate the fact that the platform has no ads and it’s hard to integrate ads if you want them. I hope they will figure this out, but the lack of sustainability discussion concerns me.

Download LinkEdit 1.1 from TestFlight…

Why Safari’s toolbar buttons are grey and almost every extension I tried offers a button with their own custom blue colour. It looks awful and it is the reason I don’t add any third-party buttons to the toolbar.

I am going back to the existing iOS app, it’s so much smoother, faster and enjoyable than Electron beta. @manton try downloading it from the App Store now over you TestFligt beta and you will know what I mean.

Nintendo Switch Year in Review. This year I started and finished Breath of the Wild. 🎮

What I like about is the sustainable business model. Mastodon server expenses have to be substantial. Especially when more people will start uploading photos and videos. How is this going to be funded?

Web devs, remove “share” social buttons form your website. There are faster and more private ways to share content, e.g. “sharrow”.

I added a diagram for my previous post about and Mastodon.

Doing some testing with Mastodon, and it looks like I can follow Mastodon users through, however, Mastodon users won’t be able to see any of the content which I post here. I am not sure I am happy with this.

YouTube “shorts” are ridiculous. I watch 90% of YouTube content on my TV. Shorts use portrait orientation and watching them on Apple TV is painful. Is there a way to remove shorts from my chronological subscriptions?

I have shipped a new update to Caffeine++ and now it supports Shortcuts. I don’t know if is it going to be useful for anybody, but it opens a door for possible automation. For example, you can automatically add a new cup of coffee every weekday. iOS 16 API is very nice and it took almost no time to add it.

An awesome dude was doing voice impressions with a mic and loudspeakers and gave kids a fun task to complete before giving away candy. Searching for jars in his front gardens and giving them to the “master”.


Started to add unit tests into my projects, but only where there’s real value. For example, verifying that a complicated function produces expected results with a given data set.

One of the days I returned home from work.

I have turned off Always On on my watch and I didn’t notice any difference. It’s been more than 2 weeks and it rarely annoys me, maybe once.

Turns out, Shortcuts behave differently depending on the way you invoke them, “Hey Siri” gives audio feedback and holding the Power button shows a dialogue box. Very clever.

It’s so difficult to debug Siri Shortcuts. A total black box.

I’m very happy Apple TV got such a great upgrade.

Let's put all iPad models on the table

The iPad lineup is confusing. There are too many models. I have tried to focus only on 4 models which I think are essential, using the famous Steve Jobs grid. It doesn’t hurt to have extra models, but it’s just a little bit less Apple-like experience when you shop. This complicates the accessories range and makes a choice more difficult. Apple engineers have to spread their focus across many models instead of focusing on quality.…

I can’t imagine buying iPad if I can’t use it with my wired headphones, same I use with my MacBook Pro almost every day.

No headphone jack in any iPad model. This wasn’t even mentioned in the video. Why? The only benefit I see is making it thinner and lighter, but this should be justified. The other benefit, kids are less likely to cause damage by pulling the headphone cable

What is your thoughts about todays news form Apple

  • New iPad colours look fun
  • There’s too many iPad models now
  • USB-C transition 👍🏻
  • Cheaper Apple TV 4K 👍🏻
  • Apple TV HD is gone 👏🏻
  • Apple Pencil hover mode for the M2 iPad Pro looks interesting

I forgot how time-expensive can be working with regular UIKit and Auto Layout. Here I am trying to fix UIScrollView, something which I know would work without any custom code in SwiftUI.

Currently reading: The Tommyknockers by Stephen King 📚

Finished reading: The Bayern Agenda: The Galactic Cold War, Book I by Dan Moren 📚

I think the author has potential and further books in a series can be great. What I didn’t like is that the plot tries very hard with politics and twists. All fight scenes were predictable, and it didn’t feel like anyone is in danger. I liked the beginning very much though, it kept me on edge. The world is interesting as well.

Fun fact, I visualized main protagonist as Takeshi Kovacs from Altered Carbon season 1.

Hello, I am back to the I was a bit too active promoting the app I made on Twitter, someone reported me and my account was deleted. There’s nothing I can do to restore it, appealing didn’t work.

Firstly I made a mistake in picking a name for my app which made it too similar to a competitor. A mistake which I have fixed by renaming Obsidius into LinkEdit. Secondly, maybe I shouldn’t tweet to each person on a thread which belonged to Obsidian. But I was very eager to tell people about my app. I hope it’s for the best and I can find a more calm audience here.

🎮 Playing Papers, Please. It’s been years since I bought game on iOS. It’s ideal for touch controls. Good port. Highly recommended. I learned about this game from this podcast episode. 🎙️…

Apple Event

This was better than expected, I would say much better than last year’s event. Apple Watch All Apple Watch models now share the latest chip. This is fantastic news, and I am especially glad.
