Issue

I upgraded my Mac to macOS Big Sur 11.6 and Xcode to 13.0. When I opened the React Native project in Xcode, an error occurred:

/Volumes/develop/node_modules/react-native/React/CxxBridge/RCTCxxBridge.mm:331:34: Cannot initialize a parameter of type 'NSArray<id<RCTBridgeModule>> *' with an rvalue of type 'NSArray<Class> *'

package.js:

react: 16.11.0
react-native: 0.62.2

Solution

Fixed by changing a parameter cast like so:

1. node_modules/react-native/React/CxxBridge/RCTCxxBridge.mm

Probably on line 771, change the code from

- (NSArray<RCTModuleData *> *)_initializeModules:(NSArray<id<RCTBridgeModule>> *)modules
                               withDispatchGroup:(dispatch_group_t)dispatchGroup
                                lazilyDiscovered:(BOOL)lazilyDiscovered

to

- (NSArray<RCTModuleData *> *)_initializeModules:(NSArray<Class> *)modules
                               withDispatchGroup:(dispatch_group_t)dispatchGroup
                                lazilyDiscovered:(BOOL)lazilyDiscovered

2. node_modules/react-native/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm
