  2. Explaining how it’s built
  • Friction is built in 3 parts, the Mac app, iPad app and sending data over the USB connection these can be seen in Xcode with the folders Friction Mac, Friction and Peertalk respectively.
  • The “Shared” folder consists of the files that are shared between the Mac and iPad clients.
    • ScreenRecordingData.swift sends data from the Mac to the iPad
    • DrawingData.swift sends data from the iPad to the Mac
  • The iPad and Mac apps are built with Swift while the communication betweent the two over a USB cable is in Objective-C
