Hello,
I have a problem with Swift Playgrounds on my iPad A16 running iPadOS 27.2.
When opening the lesson “Get Started with Apps”, I get this error:
Prewarm failed
It says that I don't have permission to save CurrentUser.txt in the Documents folder. The error suggests changing permissions using Finder, but Finder is not available on iPad.
The same problem occurs when creating a new app. The app preview (normally showing “Hello, world!”) remains blank.
I have already reinstalled Swift Playgrounds, completely reset my iPad and restored it. Apple Support also tried to help remotely, but the problem remains.
Is this a known bug in Swift Playgrounds or iPadOS? How can I fix it?
Thank you!
