Build input file cannot be found: Libraries/WebSocket/libfishhook.a’


Reference: Xcode 10 libfishhook.a cannot be found

When I updated Xcode to 10.0, I got the above error and couldn't compile ReactNative.

RTCWebSocket.xcodeproject -> RCTWebSocket -> Select Build Phases -> Add libfishhook.a to Link Binary WithLibraried.
Delete if already added.

The problem was solved by doing

  1. Turning an image into a button with ReactNative(TouchableOpacity)
  2. Display text in ReactNative
  3. A note on the commands that are only used occasionally in ReactNative
  4. Show the indicator in ReactNative
  5. Display an image with ReactNative
  6. Specifying the size of the View in FlexBox
  7. Displaying a FlatList in ReactNative
