xamarin iOS can't deploy to device (the selected device was disconnected and cannot be accessed)


I'm not able to deploy to my iOS 15.0.1 iPhone from within Rider. The device dropdown displays the yellow warning symbol and has the following error message when I focus over the device "the selected device was disconnected and cannot be accessed anymore from this machine". 

I'm able to deploy to this device from the same codebase from within Visual Studio Mac, so I know it is not an issue with my iOS SDK's, Xcode version or Xamarin forms version.

My setup is as follows:

JetBrains Rider 2021.2.1

Runtime version: 11.0.11+9-b1504.16 x86_64

Hi Lhughey

Have you updated your XCode to version 13 recently? It could be related, as XCode13 has not been fully supported yet in Rider 2021.2. 

Please try to update to 2021.2.2 or to the latest Rider EAP.

Please let me know how it works for you. Have a nice day! 


Hey Alexandra. I appreciate the reply. I've had this issue for the last 6 months but the latest version (2021.3.3) has resolved the issue and even works on the latest XCode version (13.3)! Thanks.
