Xcode 11.4: Building for watchOS, but the linked framework 'MyFramework.framework' is building for iOS

Question

My project compiled fine but after upgrading to Xcode 11.4 it now fails to compile with this error for each of my frameworks: Building for watchOS, but the linked framework 'MyFramework.framework' is building for iOS. You may need to configure 'MyFramework.framework' to build for watchOS.

I have 3 frameworks. Each have a watch version target which is already configured to use watchOS as the base SDK.

Answer 1

I removed each framework and added them back, and it compiles fine now.

The project.pbxproj changes added:

        3B2AD3CA242D1EEA00C436C8 /* PBXContainerItemProxy */ = {
            isa = PBXContainerItemProxy;
            containerPortal = 4CAF2B4E1B32D6F400489ACE /* Project object */;
            proxyType = 1;
            remoteGlobalIDString = 3B1303E423CE4DA900405D89;
            remoteInfo = "MyFramework Watch";
        };

and

        3B2AD3CB242D1EEA00C436C8 /* PBXTargetDependency */ = {
            isa = PBXTargetDependency;
            target = 3B1303E423CE4DA900405D89 /* MyFramework Watch */;
            targetProxy = 3B2AD3CA242D1EEA00C436C8 /* PBXContainerItemProxy */;
        };

For each framework.

I also filed a bug report with Apple Feedback and they closed it saying I was able to fix it myself.
