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

> **[GitHub - sendbird/SendBird-SDK-dotNET: Sendbird Chat SDK for Unity for...](https://github.com/sendbird/Sendbird-SDK-dotNET)**
>
> Sendbird Chat SDK for Unity for enablement of a rich, engaging, scalable, and real-time chat service. - GitHub - sendbird/SendBird-SDK-dotNET: Sendbird Chat SDK for Unity for enablement of a rich, ...

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  
Console.WriteLine(message);  
}

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.
