[Feature] Developer Tools

Changelog

• Replaced all NSLog and print with OSLog
• Added a hidden developer mode, activatable by:
  • tapping the build version 10 consecutive times,
  • activate the build version label with VoiceOver, or
  • in DEBUG mode with isDebugging in the launch argument (enabled by default)
• Added a OSLog view to see the logs, with basic filters and search
• Added a Network Package composer to author network packages
  • Added a hidden network package debug mode that sets capabilities to all network packges, activatable by:
    • typing isDebuggingNetworkPackage in the Network Package composer payload text editor
    • in DEBUG mode with isDebuggingNetworkPackage in the launch argument (disabled by default)
• Replace [self] with [weak self] everywhere
  • Address crash on Battery.sendBatteryStatusOut()
  • log Battery instance leak for debugging

Note

• Debug messages are only available for viewing when attached to a debugger
• Privacy redaction is not applied to network packages (device's UUID assigned by KDE Connect and name will be exposed in the log)
• These logs are stored on users' devices only and we have no way of accessing them. Users must manually export/screenshot the logs

Known Issues

• OSLog vieweing is only available on iOS 15 because Apple didn't have time to deliver it for iOS 14
• Network Package Composer does not support adding file payload because the existing payload mechanism consumes too much memory and is hard to work with
• Contributors need to learn OSLog: https://invent.kde.org/network/kdeconnect-ios/-/wikis/Logging-with-OSLog
