iOS Notification Service Extension Deploy Fails

[borigas]

Description

I'm trying to add an iOS Notification Service Extension to my app, but I can't get it to deploy from VS. I am connected to a Mac and have a device selected.

------ Deploy started: Project: MauiDebugNotificationServiceExtension, Configuration: Release Any CPU ------
Please select a valid device before running the application.
Deploy failed
------ Deploy started: Project: MauiDebug, Configuration: Release Any CPU ------
Xamarin.iOS does not support deploying the previous version. Please ensure your solution builds before deploying it.
Deploy failed
========== Build: 2 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
========== Build completed at 2:19 PM and took 26.135 seconds ==========
========== Deploy: 0 succeeded, 2 failed, 0 skipped ==========
========== Deploy completed at 2:19 PM and took 26.135 seconds ==========

It looks like docs on how to use this haven't been done yet (https://github.com/dotnet/docs-maui/issues/1434). Instead, I referenced and tested a handful of 3rd party examples, but I get the same behavior. Examples referenced:

• https://vladislavantonyuk.github.io/articles/Extend-.NET-MAUI-application-with-iOS-Extensions/
• https://github.com/bitwarden/mobile/blob/main/src/iOS.Extension/iOS.Extension.csproj
• https://github.com/OneSignal/OneSignal-DotNet-SDK/blob/4690aad1d54d7db8ee207da16027beaeba6ad6c7/Samples/OneSignalNotificationServiceExtension/OneSignalNotificationServiceExtension.csproj
• https://github.com/exponea/bloomreach-maui-sdk/blob/main/ExamplePushServiceExtension/ExamplePushServiceExtension.csproj

Other things I've tried include:

• Updating VS, XCode, dotnet, dotnet workloads
• Rebooting Windows, Mac
• Cleaning Windows, nuget package cache, Mac build cache, *.csproj.user
• Deleting the connection to the Mac, disabling sharing on the Mac, enabling sharing on the Mac, recreating the connection
• Deploying to different simulators/devices
• Deploying to a local device with Hot Restart
• Running mlaunch directly after building from VS:
  • /usr/local/share/dotnet/packs/Microsoft.iOS.Sdk/17.2.8053/tools/bin/mlaunch --installdev ~/Library/Caches/Xamarin/mtbs/builds/MauiDebug/a30afb1d33bf5430897cbab9d42475927750458aadbcba47ce68f91a270a4fc6/bin/Release/net8.0-ios/iossimulator-arm64/MauiDebug.app --devname ocv6splus --wait-for-exit:false
    • Errors with error MT1006: Could not install the application '~/Library/Caches/Xamarin/mtbs/builds/MauiDebug/a30afb1d33bf5430897cbab9d42475927750458aadbcba47ce68f91a270a4fc6/bin/Release/net8.0-ios/iossimulator-arm64/MauiDebug.app' on the device 'ocv6splus': AMDeviceSecureInstallApplicationBundle returned: 0xe8008014
• Building with dotnet build:
  • dotnet build -t:Run -f net8.0-ios -p:RuntimeIdentifier=ios-arm64 -p:_DeviceName="ocv6splus"
    • Errors with

    EXEC : error MT1006: Could not install the application 'bin/Debug/net8.0-ios/ios-arm64/MauiDebug.app/' on the device 'ocv6splus': AMDeviceSecureInstallApplicationBundle returned: 0xe800801c. [~/Repos/MauiDebug/MauiDebug.csproj]

Steps to Reproduce

Try to run/deploy/debug from https://github.com/borigas/NotificationServiceExtensionRepro or any of the other examples mentioned above.

Or create a fresh Maui app with an iOS extension. To modify the Xamarin iOS extension to .NET 8, use this csproj:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFrameworks>net8.0-ios</TargetFrameworks>
    <OutputType>Library</OutputType>

    <ApplicationId>MauiDebugNotificationServiceExtension</ApplicationId>

    <ApplicationDisplayVersion>1.0</ApplicationDisplayVersion>
    <ApplicationVersion>1</ApplicationVersion>

    <Nullable>enable</Nullable>
    <TreatWarningsAsErrors>true</TreatWarningsAsErrors>
    <ImplicitUsings>enable</ImplicitUsings>
    <SupportedOSPlatformVersion>15.4</SupportedOSPlatformVersion>
  </PropertyGroup>

  <PropertyGroup>
    <IsAppExtension>True</IsAppExtension>
    <IsWatchExtension>False</IsWatchExtension>
  </PropertyGroup>
</Project>

I'm not convinced this is a problem with VS or VS Code. I can't deploy an iOS extension using VS, VS Code, dotnet run, or mlaunch. That said, I have created a feedback item at https://developercommunity.visualstudio.com/t/iOS-Notification-Service-Extension-Deplo/10665806 as well

[mattleibow]

This is more likely an issue with the iOS SDK or the mlaunch tooling. Probably not directly IDE issues, but the people that fix deployment issues are the best. And since this is also VS and Pair to Mac, I am thinking this is best on that side.

I'm closing this one as you opened a new one in the developer community where IDE people live.

[borigas]

It's been 3 weeks since I posted using the VS feedback tool but haven't seen any evidence that a human even read it. Are you sure the IDE folks are still there?

I also want to clarify from your previous post that this is not VS or Pair to Mac specific. It does fail from VS with Pair to Mac, but also fails from VS Code on a Mac, from dotnet run directly on a Mac, and from mlaunch directly on a Mac.

[trampster]

We are also having this issue.

My workaround so far is to make my reference to the iOS extension project have a condition so I can skip it when deploying from VS. At least that allows the rest of my app to deploy. Then my build server sets a property to enable the extension project so it gets packaged in the IPA. It makes for a pretty terrible dev loop, but at least it's possible to deploy the rest of my app again.

I created https://github.com/xamarin/xamarin-macios/issues/20918 to see if they're able to offer insight. Visual Studio Developer Community doesn't seem to have anyone reading issues.
