Apple Developer Weekly #237 Beta 3
Where Did the Liquid in Liquid Glass Go?
From 13
This newsletter is a few days late because I decided to extend my vacation and was traveling without a good work environment. Plus, there was less developer news last week, so I took a few extra days to gather more content.
iOS 26 Beta 3 reduced the liquid effect of Liquid Glass so much that many people feel it's completely lost its impact. I guess they'll adjust it back in future beta versions.

🚢RevenueCat Shipaton 2025
RevenueCat announced Shipaton 2025. This is a meaningful event that encourages developers to build and ship apps through various incentives. The total prize pool is worth $300,000 USD.
The iPlayground conference appears at the 204-second mark in the official video. Coincidentally, iPlayground's schedule overlaps with Shipaton this year, and RevenueCat is a sponsor, so there will be booth activities at the event.
ChaoCode also released a related introduction video and announced they're joining the competition.
As for me, I was too busy to participate last year. This year, I want to finally build and ship my own app. Welcome to join the fun!

📚onevcat's Swift Concurrency Book Updated to Swift 6
onevcat announced that his book "Swift Concurrency" has been updated to Swift 6. His reflection in this tweet is worth savoring:
In the era of large language models, the format of technical books obviously can't keep up anymore. It feels like they'll eventually just become fodder for LLMs. As a human, I don't know whether to feel relieved or sad about this.
📖Paul Hudson's New Book Everything but the Code Launches July 14
Hacking with Swift author Paul Hudson is launching a new book, "Everything but the Code."
The book's concept is similar to my previous idea of an "iOS Developer Completion Plan" - covering all the developer knowledge beyond just writing code. But obviously, his content is much richer, and he's gathered insights from experts across various fields.
If you're interested, it'll be available for purchase next week.
🤖Foundation Models beta 3 Adds GeneratedContent API
I happened to notice SwiftUI team engineer Julian Schiavo sharing that Foundation Models added the GeneratedContent API in beta 3.
This lets you generate your @Generable models outside the FoundationModels framework, via JSON or other methods (here "models" refers to data objects, not language models 😂).
🎯Airbnb Tech Blog Shares Understanding and Improving SwiftUI Performance
The Airbnb engineering team shared their experience improving SwiftUI performance on their tech blog. For teams using SwiftUI to develop large-scale applications, this is excellent reference material.
