As the headline hints I get the following error message, when uploading my ipa file to the App Store
ERROR ITMS-90733: "The binary you uploaded was invalid"
It appears to be a problem specifically for iOS apps with an Apple Watch extension which suits my case
Similar to the Xcode users on the thread https://forums.developer.apple.com/thread/108405, my issue appeared when updating Xcode (and Xamarin) to the version offering emulators for the new Apple Watch S4. My current VS version is 7.6.9
The Xcode users have overcome this issue by changing the architecture settings for the Watch Extension project. I have tried multiple variations of architecture settings, but unfortunately I have not been successful
The other thread mentions choosing the architecture for the watch extension to be "arm64_32 and armv7k". arm64_32 is not an option I can pick, and when I add the architecture settings manually using a text editor I get the error, that it could not parse the architecture settings, when building the ipa file
Anyone got this problem?
