⚠️ Breaking changes ⚠️

None.

Introduced changes

Unified logging macros in Objective C iOS layer. Supports error, warning, debug and trace levels.

The logs can are filtered in multiple ways:

• In compile time due to Release/Debug modes.
• In runtime via an environment variable. The variable can be set either in XCode or via a script (see later PR feat: unified build and run fabric-example scripts #1375).
  • It is especially useful for trace logs as they can be very performance intensive, so it is bad to have them enabled even in Debug mode by default.
• Using new yarn workspace fabric-example log:stream:ios script via --level flag on the computer.
  • The script allows to filter according to subsystem, module, level and a regular expression.

Checklist

• Updated relevant documentation (It is done in a later PR in this GitHub stack)
• Performed self-review of the code
