## Create xcframework

Merge the arm64 and x64 libraries of macOS.

```bash
mkdir -p out/mac-x64-arm64-lib
cp -R out/macOS-x64/WebRTC.framework out/mac-x64-arm64-lib/WebRTC.framework
lipo -create -output out/mac-x64-arm64-lib/WebRTC.framework/WebRTC out/macOS-x64/WebRTC.framework/WebRTC out/macOS-arm64/WebRTC.framework/WebRTC
```

Merge the arm64 and arm libraries of iOS.

```bash
mkdir -p out/ios-device-arm-arm64-lib
cp -R out/ios-arm64-device/WebRTC.framework out/ios-device-arm-arm64-lib/WebRTC.framework
lipo -create -output out/ios-device-arm-arm64-lib/WebRTC.framework/WebRTC out/ios-arm-device/WebRTC.framework/WebRTC out/ios-arm64-device/WebRTC.framework/WebRTC
```

Merge the arm64 and x64 libraries of iOS simulator.

```bash
