Error running app with Hot Restart

I am trying to debug a test app using Hot Restart but it will not launch. The Build Output window shows that the app has been successfully deployed to the iPhone. I see the icon on the iPhone but when I try to start the app it opens something for a short period of time and then it closes. The Build Output window reports that: An error occurred while trying to launch the app 'MVVMDemo.iOS'. Details: Error running hotrestart: 'An error occurred while disposing the 'com.apple.debugserver' service. Details: Value cannot be null.'. Command: 'launch -u=8c5ef99b1c1907ce22b4eb3f5d4a848839e78255 -i=com.companyname.MVVMDemo -p=10000 -d="C:\Users\xxxxx\AppData\Local\Xamarin\iOS\DeveloperDiskImages\14.3\DeveloperDiskImage.dmg" -w=True'

Hello,


Welcome to our Microsoft Q&A platform!

This is a known issue about hot restart : https://github.com/xamarin/Xamarin.Forms/issues/13759 .

And the issue has been fixed and will be available soon in the next VS 16.10 Preview and also in the next VS 16.9 Service Release.


Best Regards,

Jessie Zhang

Not fixed!!!

Just installed latest VS update, 16.9.6, and still failing with same error message. App will compile, deploy, but debugger cannot start with same message above about com.apple.debugserver. Instead, it tells user to start manually, which of course then means no debugging.

Dead in the water here, and frustrated.
