Application output doesn't log properly

Amir-JAmir-J USMember ✭✭

Hey guys,

I have a rather frustrating situation. Application output doesn't log all the times. Some times it does, some times it doesn't. I have tried nearly every possible way for the past few hours.

I clean project, remove content from bin folder, restart the whole IDE. It still doesn't work.

Here is a simple situation,

Brand new iOS native App
iOS Simulator (I have tried 5 different simulators and iOS versions including, 6, 6s, iOS 9.3, 9.2 10 and 10.2)
Build Debug mode

I make a simple buttons that when clicked on it does:

Console.WriteLine ("test");

It won't log anything. Basically, the application and even the generic debug OS content only shows up in the application output only if I have completely cleaned the project, manually removed the content of bin folder and restarted XS. Even then, a Console.WriteLine that is in the ViewDidLoad will print but then one in a method for a button just won't.

I am using Xamarin 6.2.1 (build 3) and I can't tell you how frustrating it is. When I have an error or when the application crashes, I simply don't get any logs to understand what's wrong.

Any advice would be great

    Possibly this bug?
    The bug is marked as fixed but the fix has not been merged into a released version of Xamarin.iOS yet. There is a workaround you can use in the comments:

    Hi Jon,

    That's the same bug. I am working on an app with backend and constantly need to check if there are issues, so I ended up writing a solution for myself.

    showTextView ("Some value to show");

        private void showTextView(String valStr)
            UITextView toastTextView = new UITextView();
            CoreGraphics.CGRect textViewFrame = View.Frame;
            textViewFrame.Size = new CoreGraphics.CGSize(textViewFrame.Size.Width * .9f, textViewFrame.Size.Height * .6f);
            toastTextView.BackgroundColor = UIColor.LightGray;
            toastTextView.Text = valStr;
            toastTextView.Frame = textViewFrame;
            toastTextView.Center = View.Center;
            UIButton dismissButton = new UIButton();
            dismissButton.Frame = new CoreGraphics.CGRect(0, textViewFrame.Size.Height - 40, textViewFrame.Size.Width, 40);
            dismissButton.BackgroundColor = UIColor.DarkGray;
            dismissButton.SetTitle("Dismiss", UIControlState.Normal);
            dismissButton.TouchUpInside += (object sender, EventArgs e) =

    I don't know if it'll help anyone, but I though I'd share it.
