Your app looks great on your phone. Now try it the way your users actually set theirs up.

Version one stays on people’s phones longer than you think. Most apps learn this the hard way.

[Swift Language @SwiftLang]

Swift 6.4.1 is out now! ⚙️ This maintenance release improves compiler stability, enhances dependency resolution in Swift Package Manager, and includes fixes for Foundation and Swift Testing. More here: https://t.co/VZNkTDVtt3

[Penguin @thepenguintech]

People are paying for your app, and your app may never find out. Watch to see how it happens, and the fix that takes an afternoon.

Apple will reject your app if people can create an account but have no way to delete it inside the app. AI tools usually build the sign up screen & skip this one, so it's worth checking before you submit.
