How to debug MAUI.iOS app from VS Windows 2022

Huynh Than 65

Hi, I'm trying to debug the MAUI.iOS app from VS Windows 2022. I connected to the remote mac successfully. This Mac mini is using Xcode 15.2 and have VS Mac 2022 installed.

When I ran, I saw it deployed successfully to the Mac, and the app also opened the splash screen. After that, it stopped suddenly. I can confirm the app works fine when deploying directly on Mac. Below is the log:

INFO: Disposing input and output streams...

INFO: Closing debug connection from device (USB)

The app has been terminated.

ERROR: An error occurred when writing to the output stream. Details: Unable to read data from the transport connection: interrupted.

ERROR: An error occurred while writing to the debug stream. Details: Cannot access a disposed object.

Object name: 'UsbStream'.

INFO: Closing debug connection from remote debugger (TCP)

INFO: Disposing input and output streams...

INFO: Disposing console and debugger streams...

Do you mean you can debug the app on the simulator via VS for Mac?

Currently, you are debugging the app on your physical device, right? Does your device connect with your PC through USB? And do you select the "Local Device" for testing?

From the error message, it looks like you are using HotRestart. You said you are successfully pair to mac, please check if you can run the app on the simulators and if you can run the app from "Remote Device".

No, I used a physical iPad that plugged in to the Mac mini.

I run the debug from a Windows machine. I choose iOS Local Device and select iPad as a result of successful pairing with a Mac Mini.

Answer 2

Hello,

You debug the app via Local Device. Please plug your iPad into the Mac and make sure your Windows machine has paired to the Mac, then you could try to select the remote device (your iPad) to debug instead of Local Device.

Best Regards,
