Xamarin iOS unable to debug over local device iOS 17.1.1

Alex 0

I have two real devices:

iPhone 15 Pro Max iOS 17.1.1
iPhone 7 iOS 15.7.8

I'm trying to debug my Xamarin application over a real device. Using my iPhone 7 works as expected. But it has been impossible for me to do the same using my iPhone 15 Pro Max.

Xamarin.iOS does not support running or debugging the previous built version of your project. Please ensure your solution builds before running or debugging it.

Keeps on popping on my screen. Also my Error List tab is showing the following:

error MT1045: Failed to execute 'devicectl': 'devicectl -j /var/folders/sx/z644_31d36l4lvbqn3kh4yl40000gn/T/tmpQa6AoB.tmp device install app --device "iPhone de Alex" /Users/alex/Library/Caches/Xamarin/mtbs/builds/MyApp.iOS/36146cef03c6dc5d96831a19912e2eba12555937b6af687d85e404c7a773ae5e/bin/iPhone/Debug/device-builds/iphone16.2-17.1.1/MyApp.iOS.app' returned the exit code 1

I have tried everything that I could think of:

Revoke all my provisioning profiles & certificates and generate them all over again.
Remove my apple developer account from VS and put it back again.
Clean & Rebuild
Manually remove bin and obj and Rebuild
Disable HotReload
Restart everything

Nothing is working. I also tried to debug over iOS 17.2 and iOS 17.4 (lastest one) simulators, and everything is working as expected. But, for my scenario, I must debug using a real device.

My environment:

Windows 11
Microsoft Visual Studio Enterprise 2022 (64-bit) - Version 17.9.6
macOS Sonoma 14.4.1
Xcode 15.3

I can provide logs, just tell me what you need

Do you add any capabilities for your app, such as push Notification, HomeKit and so on? And how did you re-generate the certificate and provisioning profile?

In addition, I noticed that you are using Xcode15.3, do you have the same issue when using Xcode15.2?

(If you need to download Xcode 15.2 you can get it from the Apple Developer portal.)

I'm following these steps:

Requesting a CSR in Keychain application

Generating certificates for Apple&iOS development

Generating certificates for push notifications for my application (Sandbox & Production)

Generating provisioning profiles using the development certificates

Download all certificates into my keychain

Download all profiles into my xcode

So yes, my application has push notifications capability.

I haven't tried with xcode 15.2 yet. Is there anything I could try before installing xcode 15.2?

Download all certificates into my keychain Download all profiles into my xcode

You cannot debug the app via VS for mac either, right? From the description, it looks like you are using VS2022(Windows), please download the provisioning profile on your Windows machine. Open VS->Tool->Options->Xamarin->Apple Accounts, add your apple developer account and download the certificate and profiles. (If your apple developer account is type of individual account, please sign in with App store Connect Api Key) And you should select the provisioning profile manually, refer to Manual provisioning for .NET MAUI iOS apps - .NET MAUI | Microsoft Learn (This doc is about MAUI, it applies to Xamarin) If you still have the problem, please try using Xcode 15.2.

Yes, I have also tried to remove my apple account from VS windows and put it back again and download all profiles again. No luck.

I have been trying to debug from Visual Studio Mac (Visual Studio 2022 17.6) for the last couple days but it has been impossible. I keep on getting

Xamarin ios waiting for debugger to connect on port 10000 via usb

And VS won't even install the application on my device. Even if I try AdHoc | iPhone the application won't be installed. I get a pop up saying the application has been installed, but the application is nowhere to be found in my device.

I'm going to try to download Xcode 15.2. Just to know, when you have multiple Xcode versions installed on your mac, you have to select the default one by running the following command, right?

sudo xcode-select -s <path/to/>Xcode.app

Tried with Xcode15.2:

Download xcode from https://developer.apple.com/download/all/?q=xcode.%2015.2

Move it into /Applications (renaming it as Xcode 15.2)

Change the default Xcode sudo xcode-select -s /Applications/Xcode\ 15.2.app

Restart mac

Check which version of Xcode is Visual Studio Mac using:

After this, results are exactly the same as with Xcode 15.3.

On Visual Studio Windows: Xamarin.iOS does not support running or debugging the previous built version of your project. Please ensure your solution builds before running or debugging it.

Already done that, on my xcode 15.2 after setting it as defualt xcode for my mac. I'm getting the same result over and over again:

Please remove the bin/obj folder and test again. Could you run the app on any simulators?

I never had problems running it on simulators. After deleting bin/obj nothing changes

Your device has been registered in your Apple developer account, right? Could you double-check if your device ID is included in the provisioning profile?

Yes, both my real devices are included in the provisioning profile.

Hello,

Xamarin.iOS does not support running or debugging the previous built version of your project.

Please open Xcode, go to Settings->Location->Command Line Tools, and then choose Xcode15.2.

Best Regards,
