Cannot install my app on my iPad. Error MT1006: Could not install the application

Question

I always get this error in Visual Studio on Windows when I try to debug my iOS project on my iPad:

error MT1006: Could not install the application '/Users/kimstrasser/Library/Caches/Xamarin/mtbs/builds/MyAppiOS/32f79b8f682b34723c1c51ad8d136c490105a1a152109fdef3a3729d3eaaa0b7/bin/Debug/net9.0-ios/ios-arm64/MyAppiOS.app' on the device 'iPad Kim': One or more errors occurred.

My Apple account is added in Visual Studio and I have chosen my certificate Apple Development and provisioning profile Development in my iOS project properties-->iOS-->Bundle Signing.

Why is it not working?

Answer 1

Hello,

A valid provisioning profile for this executable was not found

This error means that there is not a valid provisioning profile for your app (and your iPad device)

My Apple account is added in Visual Studio and I have chosen my certificate Apple Development and provisioning profile Development in my iOS project properties-->iOS-->Bundle Signing.

Please follow the steps below to troubleshooting:

1. Select manual provisioning for your app and double-check if you still can select the provisioning profile.
2. Check if you add some iOS capabilities in the app's Entitlements.plist file. If so, the provisioning profile must contain an App ID, that matches your app's bundle identifier, with the required capabilities enabled. You may have to generate a provisioning profile manually. Please see iOS capabilities - .NET MAUI | Microsoft Learn and Manual provisioning for .NET MAUI iOS apps - .NET MAUI | Microsoft Learn
3. Check if your device is included in the provisioning profile. You could go to Apple developer portal, select the provisioning profile, and click the 'Edit' button to see if your iPad is included in the 'Devices' list. If not, you could add the device and edit the provisioning profile to include it.
4. Re-authorize the device. Opening iOS Settings, and Developer Tools, resetting "Clear Trusted computers" and then authorizing the iPad again.
5. Use the latest VS and Xcode, clean the bin/obj file of your project and debug again.

If you have any other issues during the troubleshooting process, please feel free to let me know.

Update

It works now. I have changed aps-environment in Entitlements.plist from:

<key>aps-environment</key>
<string>production</string>

to:

<key>aps-environment</key>
<string>development</string>

Yes, it's the root cause. It means that you are using APNs, the provisioning profile should be matched. Remember to change it back(production) when publishing the app on release mode.
