I am following the Trax app demo from Stanford's iOS lectures and the instructor set the app up to handle GPX files via AirDrop, but the iPhone simulator doesn't support AirDrop.
Is there anyway to add files (more specifically GPX files) to an app on the iPhone simulator? I thought about emailing it to myself and using Safari on the simulator, but I have no idea where that would be stored or how to access it from the Trax app.
You can add a GPX file to a project by opening the scheme editor: Product -> Scheme -> Edit Scheme. Under Options check the Allow Location Simulation box and from the dropdown choose Add GPX File to Workspace.
In order to generate a GPX file with your custom location you can use this.
