Can you please provide the full environment information and a test application to reproduce the issue.
Easiest way to get exact version information:

- On Visual Studio for Windows: "Help menu", "About Microsoft Visual Studio" item.
Then copy/paste the version information (you can use the "Copy Information" button).

project for leak
here is the project ,and my iPhone is SE, both has this problem on iOS10.3~11.1.2.
Can you tell me how you found the leak? Xamarin Profiler? Instruments? What instrument did you use? A little more of context would be super appreciated
Sorry I missed your first screenshot, this is kind of expected and documented here:
"Xcode Instruments is a tool that can be used to profile Xamarin.iOS apps on a device or in the simulator. Mono uses its Just-in-Time model to compile code and Instruments doesn’t interpret this kind of data well..."
I would recommend using Xamarin's Profiler instead.
