Usage
To start using TraceLog in your application, you need to follow these steps:
- Import the TraceLog module in the files where you want to use it:
- Use the various logging functions provided:
- Customize log levels, formats, and destinations as per your requirements:
import TraceLog
TraceLog.verbose("This is a verbose log message.")
TraceLog.logLevel = .info
TraceLog.logFormat = .verbose
TraceLog.logDestination = .console
Custom Log Formats
You can define custom log formats using placeholders to include additional information in the log output:
- %d: Date and time of the log event.
- %n: Name of the logger.
- %l: Log level of the message.
- %M: Method name where the log statement was invoked.
- %F: File name where the log statement was invoked.
- %L: Line number where the log statement was invoked.
- %@: The log message.
Examples
Here are some examples to help you understand how to utilize the TraceLog framework effectively:
- Simple log statement:
TraceLog.verbose("This is a verbose log message.")
TraceLog.logFormat = "[%d] [%l] %@" // Output: [2022-01-01 10:00:00] [VERBOSE] This is a verbose log message.
TraceLog.logLevel = .warning // Only logs with warning level or above will be displayed.
TraceLog.logDestination = .file("logs.txt") // Logs will be saved to the specified file.
Conclusion
TraceLog is a robust and efficient logging framework that simplifies debugging for iOS and macOS applications. With its flexible configuration and powerful features, developers can efficiently track and analyze application behavior to identify and resolve issues.
