Prerequisites

  • Having already installed and launched each app before

  • Using

Steps

  • For the first application, you can launch it as you would normally:

    • Open it with xcode xcode ./ios/your-first-app.xcworkspace

    • Open React Native Debugger

    • Launch the simulator from xcode with the play button on the top left

CHECK In RN debugger, you can see logs from the first app.

  • For the second application:

    • Open it with xcode xcode ./ios/your-second-app.xcworkspace

    • Modify the port used by the packager in the native code:

      • Do a full project search with "Maj + Cmd + F"

      • Look for "8081"

      • Replace "8081" by a new port, like "9980"

      • Save each change

    • In React Native Debugger:

      • Open a new window "Cmd + T"

      • Enter your new port "9980"

    • Launch the simulator from xcode with the play button

    • Launch a new packager from your project directory: react-native start --port 9980

    • Close and re-open the app from within the simulator

CHECK In the other RN debugger, you can see logs from the second app.

  • You are good to go! Both apps are now running with separate packagers and separate debuggers.
