Logging in Swift
In this example, you can find how to print all the logs effciently in iOS application. Along with, you will find how to share logs for debuging purpose.
By share logs, you can ask to your app user to share logs as a file so that you can debug any issue.
Example: How to print logs
You can print logs for different categories like error, info, warning, debug, verbose.
Log.p(#function, type: .info)
Log.p("this is log to test log level: error", type: .error)
Log.p("this is log to test log level: warn", type: .warn)
Log.p("this is log to test log level: info", type: .info)
Log.p("this is log to test log level: debug", type: .debug)
Log.p("this is log to test log level: verbose", type: .verbose)
Example: How to share log file
if let logFilePath = Log.fileLogger.currentLogFileInfo?.filePath {
DispatchQueue.main.async {
let fileUrl = URL(fileURLWithPath: logFilePath)
let activityViewController = UIActivityViewController(activityItems: [fileUrl], applicationActivities: nil)
self.present(activityViewController, animated: true) { }
}
}
Example: How to log Networking request and response:
While you deal with networking requests and responses in your application, you need to logs all the request and response. In Logger.swift file, you will find two seperate methods to do that.
Log.logStartRequest(request: URLRequest) // For request
Log.logEndRequest(response: URLResponse>, data: Data?, error: Error?) // For response
