react-native-webrtc: iOS Release Build - Missing Required Architecture x86_64

Steps to reproduce the problem

Everything works fine in debug mode. When I went to edit scheme -> clicked run option -> changed build configuration to Release and unchecked “debug executable”. I then went to Product -> build.

I have downloaded the bitcode thinking maybe that would solve the issue but it did not.

I tried removing my ios/pods and node_modules directories and installing everything fresh to see if that was the issue, it was not.

Expected behavior

I would expect this to build correctly.

Observerd behavior

I actually found a solution. I just had to run the downloadBitcode script as a pre build step ./node_modules/react-native-webrtc/tools/downloadBitcode.sh.

This issue is crazy. I am working on it at least 2 days and couldn’t found a proper solution. WebRTC.xcframework contains multiple architecture and when I delete arm64 compilation will success. Somehow when there is an arm64 architecture exist xcode can not compile it for simulator.

Bintray was sunset. You nee to update to 1.89.

@saghul Thank you for talking it out, sound like i just need to give the edits another crack. If i run into any issues ill make a separate issue/PR to track/discuss them if thats preferred to keeping this open.

FWIW, it you’re trying to do a release build, the pod install wont include the bitcode, you need to download that separately before you build by running ./node_modules/react-native-webrtc/tools/downloadBitcode.sh. That fixed the error for me.

Are you using CocoaPods 1.10?

I have found a solution. Somehow Xcode can not find ios-x86_64-simulator when arm64 exists. I had to deleted ios-arm64 in the xcframework and build succeed. It is not an ideal solution but it worked for me. Folder path is as described below. Just delete ios-arm64 to use on simulator.
