@MobileTen : The problem is that Apple can refuse an app for this problem which not under developer responsibility.

Not sure you do it right : you try to use navigation title for each tab. The logic off this is not clear : you should use a Text at the top of the view. As your tab view is inside a view inside a navigation stack the navigation title should be on the tab view.

Seems you are using some deprecated functions from coreAudio . This may be related : do you have any warning during compilation ?

Did they check that there device version is compatible ?

begite submitting app for review you can choose between 3 options : publish manually publish automatically when validated publish after delay this is at the bottom of page where you enter app information

Currently (2022-05-12 17:01 gmt+2) I can access App Store Connect . Possibly same problem as this post

Did you explain this to apple review team ?. Have exact different icons, names , descriptions ?

when On App Store Connect , do you see the build in TestFlight ? If yes, did you set the cryptography requirements ? If yes did you send invitation to email user ?

I could find a way to suppress the warning by adding LSMinimumSystemVersion : 12.3 in Info.plist. It seems that the one specified in xCode in info tab is not used. For information, it is a SwiftUI app with MacCatalyst activated (optimised for Mac) with minimum 12.3 in info tab.

I have the same problem with app submitted to TestFlight and running on iOS10.3.4. using xCode 13.4.1 to build App run fine started from xCode (debug or release mode) on the device App run fine on device under iOS 15.7 even with TestFlight Problem is there since at least 01/09/2022 Feedback : FB11529856

the preview is not a full simulator and should be used only for design: that is how i use it.

Did you tried to install the app from TestFlight ? It may gives different results.

Did you search in the device console log for an error at start of the app . Currently there seems to be a problem of «library not loaded » on some iOS version (eg : iOS 10.3.4)

App on AppStore work until the end of your enrolment period and is automatically kept if you renew it. You will need to upgrade your certificate to submit after the end time of the certificate.

Seems that xCode 13.4.1 can not distribute for pre iOS11( this can be checked in TestFlight). Even if debug is still possible. The only workaround I found was using xCode 13.4 and doing some extra configuration : Build Settings / deployment / oAlways Embed Swift Libraries = Yes Build Settings / deployment / strip swift symbol = No Also when uploading : unselect 2 first options about BitCode and Strip Swift Symbols Tested successfully with iPhone 5 iOS 10.3.4 In the release notes of xCode it is not always easy to determine the lowest supported iOS version. New xCode 14 suppressed iOS10 and below support : it means all non 64 bits processor devices not supported. Debug is no more possible.
