Hi, I have the same issue with Xcode 13.1 on my react native projet. ***/node_modules/react-native/React/CxxBridge/RCTCxxBridge.mm:331:34: Cannot initialize a parameter of type 'NSArray<id> *' with an rvalue of type 'NSArray *' ***/node_modules/react-native/React/CxxBridge/RCTCxxBridge.mm:776:79: Cannot initialize a parameter of type 'NSArray *' with an lvalue of type 'NSArray<id> *__strong' ***/node_modules/react-native/React/CxxBridge/RCTCxxBridge.mm:827:69: Cannot initialize a parameter of type 'NSArray<id> *' with an lvalue of type 'NSArray *__strong' In my RCTCxxBridge.mm file, I don't find the ligne 624 with "NSArray<id> *)modules" but "NSArray *moduleClassesCopy = [moduleClasses copy];". I have searched "NSArray<id> *" on this file and found 2 results : (NSArray<RCTModuleData *> *)_initializeModules:(NSArray<id> *)modules withDispatchGroup:(dispatch_group_t)dispatchGroup lazilyDiscovered:(BOOL)lazilyDiscovered (line 771) AND NSArray<id> *extraModules = nil; (line 669) I changed them by : (NSArray<RCTModuleData *> *)_initializeModules:(NSArray *)modules withDispatchGroup:(dispatch_group_t)dispatchGroup lazilyDiscovered:(BOOL)lazilyDiscovered AND NSArray *extraModules = nil; Now I have those errors : ***/node_modules/react-native/React/CxxBridge/RCTCxxBridge.mm:671:20: Incompatible pointer types assigning to 'NSArray *' from 'NSArray<id> *' AND ***/node_modules/react-native/React/CxxBridge/RCTCxxBridge.mm:673:20: Incompatible pointer types assigning to 'NSArray *' from 'NSArray<id> *' Could you help me, please ?
