Apple Watch Compass App Source Code

Sorry, but it simply is not going to happen. Apple apps can also use Private Frameworks that are not available to developers. They are not going to make the source code of the Compass app available to the public. Feel free to ask, but they have never done it in the past and there is no indication they will do it now.

Apple does support Open Source projects and maintains several technologies, but none of them are apps. They are useful for developing your own apps though.

The Apple Developer membership includes Code Level Support to speak with Apple Engineers for problems with your code.

The Apple Developer Forums are also a great resource when you are stuck on a particular part of your code.

Those are the resources you have to make great apps. You will not get the Source Code that you desire.

Adding on, if you do manage to get your hands on the source code for Apple apps, they still have to go through the app review for the App Store. Which will then be sure to land you in some trouble.

Though I did find some design resources from Apple for developers making apps! ⇢
