You first have to build your project for ios:
ionic build ios Then you have to open up (with Xcode) the .xproj project that was generated by ionic build ios command (you'll see the exact location in the command's output).
Now you have to connect your iPhone to you Mac computer and you'll be able to choose your iPhone as a "deployment" device.
Click run in Xcode and after the Xcode finishes guiding you through creating a provisioning profile you'll have the app on your phone.
