_UIPopoverView, the private class responsible for rendering popover view controllers' chrome, got a glow up in iOS 27 beta 5 with a more...liquid?...Liquid Glass transition.

Appears to be using the same blobby animation trickery as _UIContextMenuView.

Looks fantastic!

Good news and bad news for fans of the old variable blur navigation bar background, Apple have added 3 new styles in iOS 27...buuut they're private 🫠

UIScrollEdgeEffectStyle has gained three new class methods: _photosStyle, _messagesStyle, and _safariStyle.

The Photos and Messages styles are pretty similar, but photos has a more aggressive gradient scrim. The Safari style is indistinguishable from the public hard style to my eye.

As iOS apps become fully resizable, our layouts have to handle many more combinations of width and height. My new post explores how we can use SwiftUI’s onGeometryChange() to apply custom layout rules without updating state for every measurement: https://t.co/8ty6A3SALy

I'm satisfied with making a cute TestFlight badge.

What TestFlight is still a secret

Did you know that Xcode 27 can generate multiple SwiftUI preview variants from a single array?

With Preview(arguments:), every fixture becomes an independently selectable state in Canvas — without duplicate previews or a VStack

🇹🇼冷知識：台灣是 iOS App Store 第四大市場
前陣子為了準備 iOS AI Summer Camp（為期三天、在台灣大學舉辦的免費學生開發者夏令營），去查了一下 App Store 的市場排名，才發現，台灣的軟體市場的規模名列前茅，而且我發現很多人並不知道這個事實。

Claude Code on desktop now works with the iOS simulator.

Build and run your iOS app, and the simulator opens in a panel right next to your conversation. Available today in public beta.

It took Apple 15 years to add the Markdown UTI to the iOS SDK. Fascinating nit given how Markdown shaped the world of documents

[Jordan Morgan @JordanMorgan10]

Even better, I have a new flow I think anyone can benefit from. Basically, use an agent to watch that dub dub session, and point it back to your app and ask it for suggestions using techniques from that session.

And it finds *tons* of good suggestions: https://t.co/L44OG61ijR

.md, meet Notion 👋

You can now open Markdown files in Notion as a read-only preview, then import them as Notion pages.

🎉 Apple quietly updated their session on Foundation Models with a larger context window in Beta 3!

[Vincent Pradeilles @v_pradeilles]

New in iOS 27: iPhone apps can opt to have their tab bar convert into a side bar menu when enough space is available.

(definitely not connected to an upcoming iPhone fold 😏)

[ビスター(Vistar) @vistar941]

The UIKit API for navigation bar minimization announced at WWDC is now available in Beta 3!!
It’s called UIBarMinimization and lets you configure minimization, restoration, and safe area behavior together.
And yes, there’s an Objective-C API too 🙌

[Enid @ios_dev_alb]

SwiftUI Tip 💡

In iOS 27, use toolbarMinimizeBehavior() to automatically minimize the navigation bar while scrolling.

Xcode 27 beta 2 ships with a new MCP for LLDB!

I wish I was not on a holiday so I could play around with it 🙈 who can do it for me?

Every iPhone with an A12 or A13 chip - XS/XR, 11, 2020 SE - has an unpatchable SecureROM exploit. The root bug is in Synopsys’s USB controller, and is exploitable. Requires physical access. Solution: buy a new iPhone. https://t.co/xF1JIJrEke

[Flo writes Code @FloWritesCode]

There are MAJOR ASO-related changes coming to the App Store in iOS 27.

Every developer gets access to several new media slots:
- banner images
- banner videos
- search results banner
- search results video

These are super important for ASO and ASA. Don't sleep on this!

Avec iOS 27 et macOS 27 c’est encore + facile qu’avant de modifier votre localisation

Avant fallait faire l’app sur Xcode (très facile hein mais quand même)… maintenant il suffit d’ouvrir Device Hub et de mettre le longitude latitude de notre choix…
