DVTPlugInQuery: Requested but did not find extension point with identifier ‘Xcode.InterfaceBuilderBuildSupport.PlatformDefinition’. This is programmer error; code should only request extension points that are defined by itself or its dependencies.

I am getting this warning while building a react native application. How do I resolve this?

  1. It seems like if I don’t touch an RN project for a couple of weeks, I get an error like this. I had this exact same issue. I tried a couple of related question/answers with no luck (Can't build react-native app due to errant recursive path issue) and (PBXCp error ….. is longer than filepath buffer size (1025)), but I don’t believe these are related to our problem. I fixed this particular issue the same way I’ve been fixing a lot of XCode issues:

    Assuming you are on Mac OS X:

    1. Close XCode and the Simulator.
    2. Go to Activity Monitor and force quit any "simulator" tasks. I had two different ones running.
    3. Open Settings->Storage Settings, then select "Developer", then delete "Xcode Caches"

    After this, try again — the application should build and the simulator should open successfully.

  2. The accepted answer by @jbnunn didn’t work for me unfortunately. Ended up being an xcode update for the iOS version I had installed. Fixed by installing the new version. In xcode:

    • Open settings => "Platforms" tab.
    • If you have an uninstalled iOS version available click on the "GET" button on the right side to install.

    Once the installation is finished you should have a new set of simulators available with the iOS version you just installed and the build should be successful.
