I put together all the proposed solutions and got a working version.
Podfile
post_install do |installer|
## Fix for XCode 12.5
find_and_replace("../node_modules/react-native/React/CxxBridge/RCTCxxBridge.mm", "_initializeModules:(NSArray<id<RCTBridgeModule>> *)modules", "_initializeModules:(NSArray<Class> *)modules")
find_and_replace("../node_modules/react-native/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm", "RCTBridgeModuleNameForClass(strongModule))", "RCTBridgeModuleNameForClass(Class(strongModule)))")
end
def find_and_replace(dir, findstr, replacestr)
Dir[dir].each do |name|
text = File.read(name)
replace = text.gsub(findstr,replacestr)
if text != replace
puts "Fix: " + name
File.open(name, "w") { |file| file.puts replace }
STDOUT.flush
end
end
Dir[dir + '*/'].each(&method(:find_and_replace))
end
After that I got a new error which is related to Flipper:
Flipper-Folly/folly/synchronization/DistributedMutex-inl.h:1051:5: 'atomic_notify_one<unsigned long>' is unavailable
I used the solution from Xcode throws 'atomic_notify_one' is unavailable to fix this problem.
# Enables Flipper.
#
# Note that if you have use_frameworks! enabled, Flipper will not work and
# you should disable the next line.
# use_flipper!()
And commented out the line # flipper_post_install(installer)
inside post_install do |installer|
Last, re-install your pods, rebuil and run your project.
