Hi,
We are trying to test application on iOS 15 and found that we are getting this message App needs to be updated.
Can anyone please let me know the reason behind this message? Existing users will have to delete the app and install again to get rid of this alert.
I'm having this issue as well. The exact same build runs fine on an iPhone running iOS 14, but doesn't open on an iPhone running iOS 15. For me, deleting and reinstalling the app does not make the error go away. I can't open my app at all.
I am facing the same issue. Apps don't launch on iOS 15 beta.
https://developer.apple.com/documentation/xcode/using-the-latest-code-signature-format According to the link above, if the CodeDirectory v value is >= 20400, it shouldn't pose an issue.
But despite the apps have CodeDirectory value as 20400, apps are not launching and it seems that Apple is forcing me to re-sign or re-build all the existing apps.
I'm having this issue as well for Adhoc distribution with Automatic manage signing turned on. I built on my MacBook running Catalina (10.15.7) and Xcode v12.3 but with the Command Line Tools of Xcode 11.3.1.
