I have same issue.

I tested userdefaults. So I saved data in appgroups, and that data not cleared after uninstall. but other data saved in userdefaults.standard, cleared after uninstall. What is the problem??? I uninstall every app in app groups, but the error still appeared. How can I do.. please help me.

Hello, I have a same problem. My iPhone os version is iOS 16.0.3, our app show a onboarding screen using userdefaults when user install the app. but my device didn't show that screen. I debugging my device, the problem was userdefaults not cleared after uninstall. Even If I login into the app, and uninstall and install again, then the login state is keep. It's very weird.... But there are some weird point there, only our app is strange in my device, other app works nomarlly. (but I don't know other app mechanism...) I think it's iOS bug. but it's not sure. My device has family sharing. so I will remove family sharing to test this. I remove family sharing and uninstall the app. but the problem still appeared.. I'm so annoying.

same problem here ~

I have a same problem. please fix this issue.

In iOS 12 have same issue. We add  -Wl,-weak-lswift_Concurrency -Wl,-rpath,/usr/lib/swift to Other Linker Flags in the app’s build settings and build using Xcode 13.2 (from developer site) but app crash on iOS 12. If you have a same problem, please TURN OFF Include bitcode for iOS content option when you upload build. then works normally.
