I have my app ready to up load for testing on Test Flight but I get the following errors (App runs fine in the Simulator and compiles for Build to App Store)
Error 2
ERROR ITMS-90725: “SDK Version Issue. This app was built with the iOS ‘9.3’ SDK. All new iOS apps submitted to the App Store must be built with the iOS ‘11.0’ SDK or later, included in Xcode [9.0] or later. Please update Xcode and rebuild your app.”
I have deleted all my profiles and started again and downloaded them again. Inspire of the Distribution and Development profile being in the keychain it still complains it can’t find the “A distribution profile is required when building for the app store.”
Keychain says these certificates are valid is there another aspect I am missing?
Finally unravelled this piece of spaghetti. It seems I have to go back to scratch every time I update Xcode… delete all profiles and start again. Now working.
