I just downloaded the new Xcode Version 12.0 (12A7209) and I am able to build my React Native project on an iOS device but not on the simulator, where I get thrown the error:
In /Users/myuser/xxx/mobile/ios/Pods/OpenSSL-Universal/ios/lib/libcrypto.a(cryptlib.o), building for iOS Simulator, but linking in object file (/Users/myuser/xxx/mobile/ios/Pods/OpenSSL-Universal/ios/lib/libcrypto.a(cryptlib.o)) built for iOS, file '/Users/myuser/xxx/mobile/ios/Pods/OpenSSL-Universal/ios/lib/libcrypto.a' for architecture arm64
Build Active Architecture Only is set to 'Yes' and I tried adding arm64 to my Excluded Architectures under Build Settings but the error persists.
