Build with Mac Requirements¶

The complete requirements for building the Loop app with a Mac and Xcode are summarized below.

Common Requirements are the same regardless of build method
Additional Requirements are needed only for building with a Mac
If you prefer to use the Browser Build method, head over to Build with Browser
As long as you use the same Apple Developer account, the app you build is the same regardless of build method
- When you install the app on your phone, settings and history are preserved; pump and CGM remain attached; selected Services are maintained

Common Requirements¶

Compatible Phone
Compatible CGM
Compatible Pump
- For pumps that do not support Bluetooth communications (older Medronic and Omnipod Eros), you also need a RileyLink Compatible Device

If using a Mac to build to a Simulator to try things out, the only requirements are a computer and Xcode.
