How to log

I am using the latest SendBird.dll in my Xamarin.iOS project that I got from here:

My app keeps crashing so would like to see logs from the SDK that I am using. I am trying to do so like this:

public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
// other code…
SendBird.SendBirdClient.Log = SendBirdLog;
return true;

private void SendBirdLog(string message)
// this never gets called

But my SendBirdLog function never gets called.

Is the log not output anywhere else?
I know the current build SDK doesn’t work on IOS.
