The WatchApp target is using “armv7k” under valid architectures; and the WatchApp Extension is using both “armv7k” and “i386” under valid architectures.
When I build and try to deploy and build to the AppStoreConnect, I get the error message attached in this post.
I tried several combinations of arm64_32, armv7, and armv64 but no luck! Any help is much appreciated. Thank you.
try add arm64_32 architecture in your watch extension build setting, not watch .
I solved the issue by switching the Build System setting from Legacy to "New Build System". You can find it by clicking File -> Workspace Settings of the Xcode.
Also you have to make sure that the Valid Architectures and Architectures settings were set to default values (just navigate to each and press backspace).
So I solved the problem by updating the AdobeMobileLibrary. Here is the link to files: https://github.com/Adobe-Marketing-Cloud/mobile-services/releases
