LGTM! The use of @autoclosure improves performance.
The log function now defers the evaluation of the message until it is needed, which is beneficial for performance.
However, the guard statement should be updated to use >= instead of <= to ensure that the log level is properly checked.
- guard Logger.logLevel <= level else { return }
+ guard Logger.logLevel >= level else { return }Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
