Lifehack: Making Logging More Convenient in Swift
<p>Usually, for debugging console output, we use the standard <code>print</code> function. For example, we might want to check whether a method is called or what data is saved somewhere. But there are many other possible use cases. Often, the number of these print statements becomes overwhelming and eventually clutters the console output. A solution to this is to create a separate caseless enum, for example, named <code>Logger</code>.</p>
<pre>
enum Logger {
// MARK: - Properties
static var isLoggingEnabled = true // Flag to enable/disable logging
}
// MARK: - Methods
extension Logger {
// Method for logging response information
static func logResponse(_ response: URLResponse) {
guard isLoggingEnabled else { return }
if let httpResponse = response as? HTTPURLResponse {
let statusCode = httpResponse.statusCode
log("HTTP Status Code: \(statusCode)")
} else {
log("URL Response: \(response)")
}
}
// Method for logging URLSession error with description
static func logErrorDescription(_ error: Error) {
guard isLoggingEnabled else { return }
print(error.localizedDescription)
}
// General method for logging
static func log(_ message: String) {
guard isLoggingEnabled else { return }
print(message)
}
}</pre>
<p>Here we have a basic implementation, plus some additional functionality for <code>URLSession</code>.</p>
