Before you start, make sure you have:

  • The latest version of WebDebugX installed
  • A computer running macOS
  • An iOS device running iOS 12.0 or later
  • The iOS device and the macOS computer on the same WiFi network
  • Xcode and the iOS development tools installed

Note: WiFi debugging requires both the iOS device and the macOS computer to be on the same WiFi network, with good network quality.
