Logger

Calls SDK for iOS offers a logging system that allows you to keep track of a number of events and activities while running your app. You can closely monitor the operation of the Calls SDK and improve debug efficiency using our log system.

To display log output to the console, implement SBCLogger.setLoggerLevel() as shown below:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    SBCLogger.setLoggerLevel(.info)
    ...
}

Log levels can be used to control log outputs. If logging is enabled at the specified log level, it also enables logging at all higher levels. The priority level of logs are in the following order: info (0) < warning (1) < error (2) < none (3).

Note: Calls SDKs for iOS and JavaScript share the same order for the priority level of logs.

The log output is written in the following format: {date time} {prefix} {type} {thread} {classFuncName} | {message}.

This class provides the following methods:

If you want to display log outputs in other tools such as device logs, console.app, or on your server, implement the SBCLogReceiver protocol to your custom log class as shown below.

class CustomLogReceiver: SBCLogReceiver {
    func log(message: String) {
        #if DEBUG
            NSLog(message)
        #endif
    }
    ...
}

class AppDelegate: UIResponder, UIApplicationDelegate {
    let myLogReceiver = CustomLogReceiver()

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        SBCLogger.add(receiver: self.myLogReceiver)
        ...
    }
}
