The app is intended for all users of the ProtonMail service. Whether they are paid or free, they can compose and read emails, manage folders and labels, manage some account settings and create a new account. The app supports iOS 10-13.

Content Explanation


  1. Have macOS up to date and install Xcode 11.1
  2. We use xUnique (ver 4.1.4) in order to prevent merge conflicts in the ProtonMail.xcodeproj file. Each shared scheme has a post-build action, and builds will fail on machines with no xUnique installed. Please follow xUnique's installation instructions
  3. DOMPurify(@b06b6b2ac8) and Cocoapods are pre-downloaded. We are using git submodules for tracking DOMPurifier, so after cloning you have to run git submodule init and git submodule update to fetch it. Theory here:
  4. Open ProtonMail/ProtonMail.xcworkspace and click the run button
