Hi, I created an application for a client. The client put me as a developer in his team on AppStore Connect. For that I use Xcode 13.2.1. It's a UIKit application in Swift with Storyboards. I built the app => no problem I tested it on my iPhone => no problem From Xcode I made an archive and uploaded it to TestFlight => no problem The archive has been received by Apple. It was then processed by Apple => no problem And finally I received a notification that it was available on TestFlight => no problem TestFlight offers me to install it but when I try it does not install it. If I try to click on the icon of the application it shows me the message "This app cannot be installed because its integrity could not be verified." I have tried installing other apps from TestFlight and have no issues. I checked on my mac for the various certificates for this client and they are all good and valid. I don't understand why for this application I have this behavior. Someone would have any idea ? Regards Harish
