### 5/5 — 很不错的学习教程

*2025-11-26*

基本上覆盖了所有想学的内容

### 5/5 — 感谢

*2025-11-22*

我看内容很规整，或者说是正式，应该是AI写的，你整理到了这个app，就算这样也是很不错的事情，因为我以前试过让ChatGPT帮我生成swift的知识点，但那样很不方便学习，非常感谢你整合到了这个app，想关注下你的X，不知道有没有办法。

**Developer response:** 开发这款 App 的时候 AI 能力还不够成熟，整体开发过程并没有借助 AI。Swift 相关内容的中文译文由 AI 翻译，英文原文直接搬运自官方文档；Swift 速查表源自开源资源，并非 AI 生成，因此这两块内容全部免费开放。SwiftUI 备忘录仅有少量内容由 AI 辅助撰写，所有内容我都经过手工测试验证。

### 5/5 — $10 per year subscription service

*2025-01-15*

I get u need to need $ to have the app on the app store but no one is going to pay $10

### 3/5 — Restore your purchases not working

*2024-09-29*

I have upgraded to Premium on my iPhone, then download to iPad Pro and noticed a couple of problems: The header on the left overlaps the menus and Restore your purchases is not working. Apart from this I found the app to be an excellent Swift and SwiftUI reference.

### 5/5 — Instant Subscribe

*2024-09-26*

Saw this on Reddit, downloaded immediately. Instant subscribe. Well worth it. One request: ability to “bookmark” certain pages, to allow quick access to important pages.

**Developer response:** In version 1.18, I added this feature.

### 5/5 — 很棒很详细的教程，很幸运能在开始学习swiftUI的阶段找到了这个app！
