在ReactNative项目中打开iOS文件下的Podfile文件，在Podfile文件最底部加上如下代码：
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(module))",
"RCTBridgeModuleNameForClass(Class(module)))"
)
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
然后别忘了在终端cd ios 然后pod install一下，重新运行即可。
