GitHub Build Overview

Build Loop with a Browser

The new GitHub build method is available with the release of Loop 3, as well as for development versions.

  • Installation on your phone is via TestFlight
  • This can be used by those who don't own a Mac but want to Loop
  • The GitHub build method can be used even if you do use a Mac - the two methods do not interfere with each other

TestFlight is the only method available for installation to a phone when using the GitHub build method, but can also be used with the Mac/Xcode build method.

Pros and Cons

Advantages of GitHub Build

Developer quote: "This frees up the dependency of having the most recent Xcode to build to a [phone with a] new version of iOS. Xcode only needs to support the iOS version on your phone when you are building directly to the phone."

  • Mac computer is not required
  • Most recent version of Xcode is not required
    • No more updating macOS then updating Xcode
    • The time required for the initial setup for GitHub may take less time than one macOS/Xcode version update
  • Updates take a few minutes of your time to start and are ready to install on your phone in less than an hour


  • There are no instructions for applying customizations
  • Stick with Mac / Xcode build (for now) if you want to customize
  • Hint - when customization instructions are provided - you will be making more forks for every submodule you customize and you will be responsible for keeping those forks up to date


Loop 3 requires iOS 15.1 or higher

Deploy and Updates

What if I get stuck?

Try to:

  • Scroll back in the directions and see if you missed a paragraph or step.
  • Compare your screen's display with the graphics in LoopDocs. Is something different or does yours have an error message? If you have an error message, does it guide you to the problem and solution?
  • If you are still stumped - reach out for help: How to Find Help.
