jitsi-meet: Can't build JitsiMeet with XCode 12.0 beta 3

Hello @saghul hope you are fine. I also have same problem. I’m using Xcode 12.2 and JitsiSDK 2.10.2

But I faced same error.

This error is due to an Apple bug, you can find more information in this discussion on the Apple Developer Forum. Normally with Module Stability, currently used for the iOS Jitsi binary framework, we should be able to use a binary framework built with Xcode 11 and Swift 5.1 with Xcode 12 and Swift 5.3 without any issue, this is the goal of the feature.

Regarding the Apple issue the current solution (explained in the Apple forum) is to remove JitsiMeet module prefix in all .swiftinterface files located here.

For example I’ve been able to build the JitsiMeetSDK 2.8.1 (built with Swift 5.2.2) with Xcode 12 (using Swift 5.3) by removing the module prefix JitsiMeet everywhere in the .swiftinterface files.

Below you can find a concrete example of the content of x86_64-apple-ios-simulator.swiftinterface file of JitsiMeetSDK 2.8.1 I manually modified:

// swift-interface-format-version: 1.0
// swift-compiler-version: Apple Swift version 5.2.2 (swiftlang-1103.0.32.6 clang-1103.0.32.51)
// swift-module-flags: -target x86_64-apple-ios11.0-simulator -enable-objc-interop -enable-library-evolution -swift-version 5 -enforce-exclusivity=checked -O -module-name JitsiMeet

A post process with a script after the framework generation can be a solution while waiting for Apple to fix the issue. I don’t know if there is another way to solve that. Otherwise I can open a dedicated issue for this annoying bug if you prefer.

Ok! Finally I have the project compiling and running fine!

I have also added ‘WebRTC.framework’ folder from the Jitsi Meet project to my project dir.
