Since WWDC25 I was able to build macOS apps with Xcode Cloud configured with Xcode 26 and macOS 26 and publish them to TestFlight Internal.

But not today: "This bundle is invalid. Apple is not currently accepting applications built with this version of Xcode."

Is that a glitch right now? Or was a glitch before that I was able to?

Coding with Xcode's Coding Intelligence is amazing. I used Aider.chat before but having the LLM directly integrated in the IDE feels very pleasing ✨#xcode #llm

C'était sport mais il ne reste plus la moindre petite référence à l'ancien nom, nul part, ni dans le Finder ni dans #Xcode (dossiers, variables, scheme ...) ! #Github

About using PDFs for iOS assets.

The problem is still relevant in Xcode and I often come across the opinion among iOS developers that PDF is a universal format for images in iOS app projects.

I will just demonstrate (see attached images below) how using pdf can visually degrade the quality of iOS app, despite the graphic designer did his job perfectly.

Marc Edwards' article describes in more detail about why this happens.

Anyone else seeing their toolbar buttons off-center in #iOS26? I am super confused here and can’t see why this is happening…

If you’re like me and don’t like the new behavior around pinning tabs in Xcode 26, there’s a setting to revert it to how it works in Xcode 16 and VS Code.

#WWDC25 #Xcode

Migrated one of the projects to Swift6... And fixed compatibility issues with macOS/iOS 26. Not going lie.. It was a painful experience. But I am glad that I did it. Sure migrating all other apps will be easier.

Speaking of code.. Does anyone know of a way to call the handler of a UIAction in a way that won't upset App Review? #Xcode #iOSDevelopment #UIKit

Is it okay to edit and add key-value pairs to the auto-generated Info.plist file? Does it re-generate and lose whatever stuff I manually added?

I'm finding an interesting difference between an M1 iMac & a M4

Regular #Xcode builds of a small project would almost always briefly max out all 8 cores of the M1, whereas on the M4 there's more differentiation on what each core does, and they mostly stay way down on the iStat display.

Apple、Xcode 26 Beta 2でApple Silicon Mac用のiOS 26ランタイムからx86_64バイナリを削除し、Apple Silicon (arm64)専用として提供を開始。

If you guys wonder what the hell is this #Spotlight process (for those who are using iStat Menus) doing.

It's not #macOS - it's #iOS 26 beta simulator 🤨 Just close it periodically to keep your computer happy.

btw: Xcode 26 beta is a different kind of memory hog as well 🙄 Hope it'll calm down over the summer as for right now it's waay more than Xcode 16.

We are getting so close to ability to actually build apps in the macOS VM https://developer.apple.com/forums/thread/787500?answerId=843094022#843094022 maybe a few more macOS iterations... after they will be done with the very important updates with Glass Design :/

❓Quick Poll: How many developers would want this in Xcode 26?
#xcode

Xcode nearly always inserts parameters at the wrong place, when „Fix“ing 🫣 Directly followed by a new „Fix“ to fix this #xcode

I found a workaround to the problem with Icon Composer not working for alternate app icons. Manually adding keys to the target's Info.plist seems to fix it for now. Seems to need separate keys for the ~ipad variant. Hopefully Apple fixes this soon. #Xcode https://useyourloaf.com/blog/adding-icon-composer-icons-to-xcode/

In #Xcode I used to option-click any file and it would open side-by-side. Now it doesn't do that in the beta.

Now I have to click File > New > Editor Pane on Right. Is there a better way?

And there used to be a button to focus/unfocus one window pane. I really miss having that.

I am so, so behind in learning what's new this year but WOW did Xcode's Playgrounds get a nice update for showing output. This will be huge for my productivity with trying sample code.

This is the same output with Xcode 16 and 26. 🤯
