I am also encountring the same problem on iOS, after Xcode update. I do not want to update to react-native 0.60

Version is react-native 0.59.3

I solved the issue by upgrading react-native to 0.59.9 version.

in your project directory, open file in myproject/node_modules/react-native/React/Base/RCTModuleMethod.mm. Then correct as below: https://github.com/facebook/react-native/pull/25146/files#diff-263fc157dfce55895cdc16495b55d190

react-native upgrade 0.59.9, yarn , yarn pods seemed to do the trick for me

open file in yourproject /node_modules/react-native/React/Base/RCTModuleMethod.mm. Then correct as quote below:

static BOOL RCTParseUnused(const char **input)
{
return RCTReadString(input, "attribute((unused))") ||
RCTReadString(input, "attribute((unused))") ||
RCTReadString(input, "__unused");
}

0.59.9 has solved this.

If for some reason you can't upgrade right now, do this as suggested by @saudahmed

in your project directory, open file in myproject/node_modules/react-native/React/Base/RCTModuleMethod.mm. Then correct as below: https://github.com/facebook/react-native/pull/25146/files#diff-263fc157dfce55895cdc16495b55d190

@decodedmrq this actually works.
But what happend? The only updated thing is IDE, no libraries were updated and moreover it was runing fine even after XCode updated. Just run into it after weekend.
