I appreciate the official RN recommended version is 0.61 but I though worth flagging that an upgrade to 0.62 breaks iOS build for real devices as per this issue.
The issue seems related to using BoringSSL and newly introduced Flipper using openSSL
Please note it works OK on simulator
My error is :
Pods/OpenSSL-Universal/ios/lib/libcrypto.a(bio_lib.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture arm64
"@react-native-firebase/app": "^6.3.4", "@react-native-firebase/auth": "^6.3.4", "@react-native-firebase/firestore": "^6.3.4", "@react-native-firebase/functions": "^6.3.4",
version = '~> 0.33.1' pod 'FlipperKit', version, :configuration => 'Debug'
PS: I also tried with FlipperKit version 0.35 with same issue.
Happy to provide more context if needed.
Sadly confirmed. Out of the box react-native-firebase is does not work on real iOS devices with react-native 0.62.
Original report was RNFBv6, I'm on RNFBv5.6.0 so it's a pretty general incompatibility. I think it might be a general problem with react-native 0.62 actually, and react-native-firebase is just collateral damage
