How can I print to console in Swift Playgrounds on iPad?

Question

I would like to debug a method deep inside my \"Sources\" folder within a Swift Playground.

public func wannaDebugThis

In order to write debug messages from the iPad to the console, NSLog() has to be used.

public func wannaDebugThis() {
    let x = 42
    let text = "Debug message with useful information: x = \(x)"
    NSLog(text)
}

The output of NSLog() can be found under the process named ExecutionExtension in Console.app on macOS. The output of print messages is only shown as , which can be seen on attached screenshot.
