ios - how to correctly build an app for device and simulator that conditionally uses the correct framework. (not a universal/fat framework)

Question

Have obtained separate frameworks for device and simulator, and I want to integrate those frameworks to achieve the desired functionality. I have included the simulator framework in my carthage framework project. When I am compiling my framework, I am getting the following error

building for iOS-armv7 but attempting to link with file built for iOS-arm64 Undefined symbols for architecture armv7: "OBJCCLASS$...", referenced from: objc-class-ref in ViewController.o "OBJCCLASS$...", referenced from: objc-class-ref in DepedencyInjector.o objc-class-ref in ViewController.o ld: symbol(s) not found for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation)

You can build a XCFramework as follows (from the command line).

xcodebuild 
    -create-xcframework 
    -framework  "<<path to simulator xcarchive>>/Products/Library/Frameworks/SomeFramework.framework" 
    -framework  "<<path to device xcarchive>>/Products/Library/Frameworks/SomeFramework.framework" 
    -output     "CombinedFramework.xcframework"

You can add more to this and set the various paths and output to taste.

Not sure if this helps as you are not looking for universal frameworks and not sure how you classify this one ...
