Module compiled with Swift 5.2.4 cannot be imported by the Swift 5.3 compiler on Xcode 12

Description

Previously I was using Xcode 11.6 to build these frameworks using Carthage. Now I upgraded Xcode to 12 and after building these frameworks when I integrate into my project and tried to run, it shows an error like:

Module compiled with Swift 5.2.4 cannot be imported by the Swift 5.3 compiler

Steps to Reproduce

1. update your Xcode version to 12.0
2. Build framework using Carthage carthage update --platform iOS (version 5.0.0)
3. Add Buy.framework and Pay.framework into any project
4. Run the project

Actual Error:

/Users/John/Desktop/Shopify Demo/API/ClientQuery.swift:4:8: Module compiled with Swift 5.2.4 cannot be imported by the Swift 5.3 compiler: /Users/John/Desktop/Shopify Demo/Shopify Demo/Buy.framework/Modules/Buy.swiftmodule/x86_64-apple-ios-simulator.swiftmodule

Workarounds I tried:

1. So few workarounds like this where you need to set the Build Libraries for Distribution option to Yes in your framework's build settings, otherwise the swift compiler doesn't generate the neccessary .swiftinterface files which are the key to future compilers being able to load your old library. But it didn't solve the issue.
2. Next I tried this Carthage workaround where you need to tweak the EXCLUDED_ARCHS statement. But it also failed.

Versions

1. Xcode v 12.0 (12A7209)
2. Carthage v 0.36.0
3. Shopify mobile-buy-sdk-ios v 5.0.0

Thanks for the feedback. We are looking into this - no more reports needed at this time.

This is now fixed in v5.1.0! We also recommend to use Swift Package Manager for managing this dependency.

I had this issue and some issue more. So I decide to migrate to cocoapod.
I am using cocoapod now and I have not any problem.
I suggest you to migrate to cocoa pod guys

[dbart01]

Use SPM instead.
