Being able to export the App Container in Device Hub in Xcode 27 is such a game changer. It will reduce a lot of of back and forth, communication and coordination between devs and testers. There will be no more “what account did you use?”, “what data did you have?”. The tester just exports their App Container, you import it and are able to reproduce the issue straightaway if it is data related. It’s just a pity it’s not possible to export the device configuration (orientation, location, language and similar settings) but maybe Apple will add support for that in the future. Also while watching this WWDC session developer.apple.com/videos/play/ww…, I missed the AI agent part. 2 humans involved in debugging that issue felt too much, too old school.

I’m so looking forward to X Money to be available in the EU.
They added a Figma Connector to Grok and Grok Build. Hopefully the Atlassian one is coming next to convince even more people to switch from Cursor, Claude Code and Codex.

We’re sharing the next major milestone in our non-invasive brain-to-text decoder research: Brain2Qwerty v2. Building on v1, which was published today in @Nature, Brain2Qwerty v2 is the highest-performing end-to-end pipeline capable of real-time sentence decoding from raw brain signals. It advances beyond character-level performance to decoding words and semantics, enabling accuracy for overall communication. We believe this research has the potential to make a real difference for the millions of people who suffer from brain lesions or disorders that prevent them from communicating. 🧵👇
I think SpaceXAI may be winning an AI race really soon. They keep shipping and improving their tools. They just released x.ai/voice. They acquired Cursor so Grok Build will be getting better and better. Grok itself is great too, especially the “Concise” mode. I deleted all other AI apps from my personal phone and left only Grok and I’m happy with its performance.
@katedeyneka How often do you need to charge them?
@vcoolish That’s the right spirit 👏
@seanallen_dev thanks for recommending it, I'm on it now too
Apple released design kits for Figma and Sketch for iOS 27 - developer.apple.com/design/resourc….
Almost everything is subscription based nowadays. TCP Viewer is different. You can pay once and have app updates as long as you are alive.
In the latest TCPViewer - our new app ✨ - Capture all packet TCP/UDP, like Wireshark - The packet panel can switch from the right-side or bottom-side mode ✅

In Xcode 27 @State changes from a property wrapper to a macro, gaining lazy evaluation of the initial value. I summarized what this means for managing @observable classes in our SwiftUI views: nilcoalescing.com/blog/Initializ… #WWDC26
Fixed in github.com/RevenueCat/pur… and released in github.com/RevenueCat/pur….
RevenueCat iOS SDK doesn’t compile in Xcode 27 beta but they are on it. Thanks @AndresBoedo! 👏
