The new TabView content is finally out! Check it out here: exploreswiftui.com/library/tabv... #iOSDev #SwiftUI

Explore SwiftUI is featured in fatbobman's latest newsletter as having “code examples stripped of unrelated logic and paired with high-quality previews.” What an honor!

Explore SwiftUI now covers the Picker with 14 examples and more than 50 screenshots. Check it out here: exploreswiftui.com/library/picker #iOSDev #SwiftUI

I somehow completely messed up my Xcode. Now every time I want to add a public Github package, I am asked for credentials. No matter how often I enter those successfully, the prompt reappears. Updating existing packages fails: repo not found Anyone experienced something similar?

Will this year be my first time attending dub dub in person? 🤔

I've started building my own tool to track SwiftUI documentation changes for Explore SwiftUI. It's still quite buggy and slow, but it will make my life much easier when creating new content and keeping existing content up to date. #iOSDev #SwiftUI

I couldn’t resist printing this guy

With the release of the MacBook Neo, I was wondering if this year's Swift Student Challenge winners would receive it instead of the AirPods Max, as this year's T&Cs do not state what the award is. But now that the AirPods Max 2 are out, it will probably be the AirPods again 😄

If you want to get rid of the Liquid Glass sidebar window design, apply .containerBackground(.white, for: .navigation) to its content. #iOSDev #SwiftUI

I am currently preparing almost 20 new entries for exploreswiftui.com, all about TabView. There are so many mighty modifiers I wish I had discovered a year ago. As usual, all examples are carefully crafted by me so you can quickly grasp what really matters. #iOSDev #SwiftUI

Any #SwiftUI expert out there who could help me get images in a TabView to work? No matter what I do, the image takes almost the entire width and height. #iOSDev

There’s an interesting change in the latest Xcode beta: the SF Symbols search now creates an Image element by default rather than just inserting the symbol name. I like the feature, but I’m not sure I appreciate it being the default behavior. FB22198451 #iOSDev #SwiftUI

With Xcode 26.4 and Swift 6.3, there is finally an equivalent to XCTSkip in Swift Testing: Test.cancel(). A canceled task is not treated as a failure and is marked with a simple gray skip icon in Xcode. #iOSDev

My website exploreswiftui.com was added to the helpful links in the r/iOSProgramming subreddit 🥺 What an honor! I regularly add new SwiftUI content and I'm always open to suggestions. #iOSDev #SwiftUI

TIL: You can rename the cases of your AppEnum without breaking existing configurations as long as the raw value stays the same. For example, renaming case1 to caseOne = "case1" works because the raw representation remains unchanged. #iOSDev

I may be a bit late to the party, but here are finally two examples of ConcentricRectangle, introduced with the OS 26 releases. It’s somewhat a smarter version of ContainerRelativeShape. exploreswiftui.com/library/conc... #SwiftUI #iOSDev

Only 48 hours remain until the end of this year's Swift Student Challenge. Take this time to thoroughly test your app, and avoid last-minute submissions. If you've already submitted and discovered a critical bug, you can still withdraw your app and resubmit.

Currently exploring localizable symbols introduced in Xcode 26 and I love it. However, one thing I don’t understand: why are some initializers marked 26+ while others aren’t? If String(localized:) can be used anyway, why is 26+ required? Can someone help me out? #iOSDev #SwiftUI

I'm preparing a deep dive for when the first new Siri beta arrives, including a benchmark of its text understanding for App Intents, Entities & Enums. If you’ve seen cases where Siri struggles with your app’s phrases or parameters, I’d be interested to hear about them. #iOSDev

Have you ever heard of LabeledContent? This element powers popular controls like pickers, steppers, and toggles. It lets you associate a value with a label, especially useful in lists. Explore its usage and variants here: exploreswiftui.com/library/labe... #iOSDev #SwiftUI

I just released WhaleDeck 3, which makes Docker management and monitoring a joy. In case you aren’t familiar, Docker enables you to run apps and services in isolated containers on your computer or server. #iOSDev #indiedev #docker

Today opened the submission for this year's #SwiftStudentChallenge for three weeks.As a two-time winner, I can highly recommend it and got to know a few nice people along the way. Here is the most important stuff you need (to know) from start to finish ⬇️

If you want to learn more about the new agentic coding features in Xcode 26.3, here’s a short tech talk by Apple: developer.apple.com/videos/play/... #iOSDev #SwiftUI

🚨 Wake up! Eleven new examples, all about sheets, just dropped on Explore SwiftUI. Screenshots for different designs and devices are available to cover the edge cases. Start exploring here: exploreswiftui.com/library/sheet #iOSDev #SwiftUI

Just a quick word of warning if you’re developing something for this year’s #SwiftStudentChallenge: don’t import assets via Xcode if you expect your app to run in the Playground/on a real iPad. They use different asset formats. I learned this the hard way last year!

👀

Hot startup idea: An app that automatically updates your IAP pricing based on the latest tariffs with a single click.

Not sure whether I should laugh or cry, but a simple timeframe description caused random hitches and slowed the UI down. Instruments helped me track it down, and caching the description fixes it for now. Amazing how much impact a "simple" text can have… #iOSDev #SwiftUI

My new app is coming together nicely. It's currently in closed beta and will hopefully be released to the public this month, or at the latest, in early February. There's already so much to explore, and the list of additional feature ideas is still growing. #iOSDev #SwiftUI

A brief service announcement: Today is the perfect day to install the important security updates you’ve been postponing all year on all your servers. Yes, even that old, crappy Raspberry Pi you shoved under the staircase and hoped everyone would forget about. Happy New Year! 🎉

Is there any way to make a native #SwiftUI macOS settings window resizable, like the Xcode preferences window? No matter what modifiers I try, I can't get it to work.

I tried something fun today: printing one of my app’s icon with an NFC tag embedded inside. For this, I designed a coin-shaped chamber where I inserted the tag during a pause in the print. Now, holding the icon near your iPhone automatically opens the app’s page. #iOSDev

Did you know iOS 26 introduces a new button initializer that only takes a role and an action as parameters? Based on the role, a fully localized label with a custom icon is generated. This also provides a native way to get the sheet close and confirm buttons. #iOSDev #SwiftUI

I've now updated all iOS screenshots on exploreswiftui.com with their Liquid Glass variants. Additionally, the code is now formatted much more nicely, and the screenshot variant is now synced with the browser’s dark mode setting. #iOSDev #SwiftUI

Exploreswiftui.com will soon see a big update with dedicated support for Liquid Glass. I’ll update screenshots of existing elements while keeping the flat versions. This also enables exploring the new language and comparing it with the old flat design. #iOSDev #SwiftUI

Every time I try to create fancy App Store screenshots for a new app, I’m reminded how bad a designer I am 😵‍💫

Here’s what I’ve been cooking lately 🧑‍🍳 more soon! #iOSDev #SwiftUI

This still haunts me 😭 The modifier doesn’t work on Tahoe, and even my workaround is broken there. Is there any other way on macOS to make a list section full-width? #iOSDev #SwiftUI

I’ve been experimenting with mesh gradients lately as colorful backgrounds that dynamically adapt to the content that’s being shown. #iOSDev #SwiftUI

I've finally managed to fully rebuild the Liquid Glass icon of WhaleDeck in 3D 🥳 Let's see how it actually looks when it's finally printed. #iOSDev

You’re an indie app developer offering special deals for Black Friday and Cyber Monday? You can submit your deals to these lists 👇 #iOSDev #SwiftUI #buildinpublic

Here’s a fun weekend project: printing my app icons in 3D. I’ll start with DriveDex because it’s the easiest to model.

I watched this session for the first time a week ago, and I now think it’s an absolute must-watch. It covers the most common causes of hangs and explains very clearly what a fix can look like. Take a look: developer.apple.com/videos/play/... #iOSDev #SwiftUI

I’m confirmed for the Apple Developer event on December 1st in Berlin 🎉 Anyone else here attending?

Interesting. Simply displaying this table seems to be extremely expensive on the main actor and it prevents the chart from updating immediately, even though fetching the data only takes a few milliseconds. Is Table really that costly to render or am I missing something? #iOSDev #SwiftUI

Here we go again: the Swift Student Challenge 2026 has been announced. Not sure if I’ll be able to enter one last time, but I definitely recommend doing so! www.apple.com/newsroom/202... #iOSDev #SwiftUI #SwiftStudentChallenge

Ugh. What a tough decision: supporting cross-device sync via CloudKit requires all primary keys to be UUIDs. My tests showed inserts up to 60% slower and queries around 30% slower with a million rows. But not having the option for sync would suck too. #iOSDev

Less than 6 months ago I built something I always wished existed – a visual way to explore SwiftUI elements and modifiers. Today, exploreswiftui.com just crossed 10k visitors 🎉 More free content coming soon, so do not forget to bookmark it :) #SwiftUI #iOSDev

Querying one million rows with 12 properties each fully locally using SQLite. I think this is pretty decent performance, especially considering that such a large dataset is only expected for a very small user base. The UI is powered by SwiftUI and Swift Charts. #iOSDev #SwiftUI

What a rough journey. I originally started this project with SwiftData, but reading got painfully slow with just a few 100k entries. Switching to Core Data solved this, but insert performance was still similar to SwiftData. I am now using SQLiteData and it's great. #iOSDev
