Apple Developer Weekly #241 Beta 6
I'm in love with that magnifying glass
From 13
To match Apple's weekly beta release schedule, the newsletter is delayed again. This week's beta 6 feels much more complete, with many operations responding very quickly. Looking forward to the official release.
I'm very happy that this issue is sponsored by the Taiwan team behind "刷刷庫" (a TOEIC exam preparation app). There's information about their team recruitment below, please feel free to check it out.

💼Taiwan Education Startup Recruitment: 刷刷庫 Team Seeking Technical Partners
刷刷庫 (a TOEIC exam preparation app) was launched by a team of two Taiwanese YouTubers, Columbus and Lily. It's already profitable on the App Store and continues to grow.
Since the current outsourced development team is shifting their focus and can no longer continue, the two founders are seeking new technical teams and collaboration methods.
They hope for two types of collaboration:
Hiring a CTO to build an internal team
Finding a suitable outsourcing team
The overall technical requirements equal the workload of one full-time iOS engineer plus one full-time Android engineer.
For detailed collaboration terms, salary packages, product status and other information, please click here to learn more.
I sincerely hope this exposure will help the team find their ideal technical partners to continue advancing this already successful educational product (regardless of sponsorship).
First, because I rarely hear success stories from Taiwan's mobile startup teams, and I hope to help. Second, because I come from an educational background myself. Third, because we're both content creators (though they're both approaching a million subscribers - I can't compare at all). Most importantly, after running this newsletter for so many years, it's rare to have developers who know to reach out to me for help.
Have readers ever wondered why 13 continues writing this newsletter? Actually, I didn't think too much about it at the beginning - I just hoped busy friends could quickly get new knowledge every week. Over the years, the newsletter has grown to over 2,700 subscribers, mostly from Taiwan, making me increasingly believe that this newsletter is the information source that the most iOS developers in Taiwan will see.
So I started looking forward to whether Taiwan developers would contact me to promote their work, or for other collaborations? Today, I finally got what I was waiting for. If any developer gains some opportunities for success through exposure in this newsletter, I would feel very honored! And please don't be shy about reaching out.
🧪Apple Releases
Note: At the time of writing, Xcode 26 has not yet released beta 6
🎵iOS 26 Beta 6 Update Highlights
iOS 26 beta 6 brings impressive updates:
First are the app opening/closing animations, catching up with the animation effects from iPadOS 26 beta 5 - very fast and smooth, the whole experience feels great.
Additionally, 7 new ringtones were added, including 6 variations of "Reflection" and the brand new "Little Bird". Many people online say Dreamersounds really nice. Of course, many people like me are permanently on silent mode and can't enjoy them.
Finally, after installation, there are new onboarding guide steps, including hint animations featuring Liquid Glass characteristics.
🔍iPadOS 26 Preview App's Adorable Magnifying Glass
iPadOS 26's Preview app added a magnifying glass feature that doesn't seem to have any practical use, but it's so cute - I'm in love with it.
That magnifying glass is actually for looking at traditional film negatives. One of my family members who is a photographer happens to use it daily, so I asked her to provide a short demo video.
📄Xcode 26 Beta 5 Hidden Markdown Documents
Xcode 26 beta 5 hides some markdown format document files, originally intended to help Xcode's own AI tools learn new WWDC APIs. But we can also proactively extract them for our own AI tools to read!
The path is /Applications/Xcode-beta.app/Contents/PlugIns/IDEIntelligenceChat.framework/Versions/A/Resources/AdditionalDocumentation.
🤖AI Tools: GPT-5 Debuts, Claude Adds Memory Feature
OpenAI officially launched GPT-5, seemingly solving the past problem of ChatGPT having too many model choices. However, initially hiding all previous model options caused dissatisfaction among many existing users. Later, the 4o option was reopened.
On the other hand, Anthropic added a beta "Memory" feature to Claude this week, which can remember content from past conversations, essentially providing cross-conversation memory capabilities. I've always thought cross-conversation memory was a strength of the ChatGPT app, so now let's see how Claude performs.
💻Cursor Launches CLI (Beta)
Since I started using Claude Code, I've left the previously most popular AI editor Cursor on the side. I think many friends who actively use AI tools have also switched from Cursor to Claude Code.
Until this week, Cursor also launched a terminal tool - Cursor CLI. Interested friends might want to give it a try.
🚴♂️Apple Maps Taiwan Cycling Navigation Goes Live
Apple Maps has started providing cycling navigation in Taiwan, avoiding hills or busy routes! This is good news for friends who like cycling.
🗺️Apple Open Sources Embedding Atlas Tool
Apple open-sourced a tool called Embedding Atlas, specifically designed for interactive visualization of large embedding vectors. This tool allows developers to more intuitively understand and process embedding data in machine learning, making it a very practical tool for AI/ML developers.
(The above paragraph was written by AI for me - I don't understand it myself, haha.)
