Xcode 11.0 build get error - Unknown argument type '__attribute__' in method -[RCTAppState getCurrentAppState:error:]
The solution is to either Upgrade to RN 59.9 or higher OR to apply this patch manually:
- go to
node_modules/react-native/React/Base/RCTModuleMethod.mm - Add the line from the patch.
Solution for this issue: go to node_modules/react-native/React/Base/RCTModuleMethod.mm and update below code
static BOOL RCTParseUnused(const char **input){ return RCTReadString(input, "__attribute__((unused))") || RCTReadString(input, "__attribute__((__unused__))") || RCTReadString(input, "__unused");}
