Xcode11.3 React Native启动报错解决方法

报错关键信息：

Exception '*** -[__NSArrayM objectAtIndexedSubscript:]: index 1 beyond bounds [0 .. 0]' was thrown while invoking getCurrentAppState on target AppState with params

[RCTModuleMethod.mm:376] Unknown argument type '__attribute__' in method -[RCTLinkingManager getInitialURL:reject:]. Extend RCTConvert to support this type.

解决方法：

找到如下文件并进行替换

替换static BOOL RCTParseUnused(const char **input)方法为

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