Description

Running projects on terminal targeting iOS fails with MSB3073 error

Notes:

1. We set the XCode both on global and VSCode as 26.3 as .NET 11 P3 is looking for XCode 26.3, it seems that it was looking for iOS 26.2
2. iOS 26.2 is not appearing anymore on our XCode after installing iOS 26.3:

3. We also tried deleting iOS 26.2 component to see if the iOS 26.2 would appear again but it still didn't work
4. We can also reproduce the issue using .NET 10 with Xcode 26.2
5. Specifying the simulator using device identifier would successfully deploy the app to iOS 26.3 simulator.
6. This issue can be reproduced on MAUI/MAUI Blazor/iOS App.

Steps to Reproduce

1. Install the .NET 11 Preview3 from here.
2. Install MAUI workload from the rollback file along with the necessary feeds: 11.0.0-preview.3_rollback.json
3. Create an empty folder name it "sample" and open it on terminal/CMD
4. Run the command dotnet new maui
5. Run the command dotnet build sample.csproj -f net11.0-ios
6. Run the command dotnet build sample.csproj -f net11.0-ios -t:Run

Actual Behavior:
There's a MSB3073: The command "/usr/local/share/dotnet/packs/Microsoft.iOS.Sdk.net11.0_26.2/26.2.11588-net11-p3/tools/bin/mlaunch --launchsim bin/Debug/net11.0-ios/iossimulator-arm64/sample.app/ --device :v2:runtime=com.apple.CoreSimulator.SimRuntime.iOS-26-2,devicetype=com.apple.CoreSimulator.SimDeviceType.iPad-Pro-11-inch-M5-12GB --stdout /dev/ttys004 --stderr /dev/ttys004 --wait-for-exit:true -- " exited with code 1. error

Expected Behavior:
The app should run using terminal without any errors or warnings.

Version with bug

.NET SDK 11.0.100-preview.3.26203.107

Is this a regression from previous behavior?

Yes, this is a regression. The issue cannot be repro on .NET SDK version 11.0.100-preview.2.26154.117.

Affected platforms

iOS

I'm a bot. Here is a possible related and/or duplicate issue (I may be wrong):

• Can't find simulator when a particular iOS SDK version doesn't contain a simulator for that same SDK version #22243

[rolfbjarne]

This is what happens:

• We added support for Xcode 26.3, but Xcode 26.3 didn't update the iOS SDK, so we're still using the iOS 26.2 SDK.
• Xcode 26.3 comes with a (supposedly) shared iOS 26.2+26.3 simulator. Not sure what's actually "26.2" about it, because it quacks very much like an iOS 26.3 simulator.
• When we try to launch an app, we look for a simulator with the same version as the SDK version. Since the app was built with the iOS 26.2 SDK (because there is no iOS 26.3 SDK), we look for the iOS 26.2 simulator - which we can't find, because it doesn't exist.

This will fix itself for Xcode 26.4, because then there will be corresponding iOS 26.4 SDK as well.

As a workaround, it should be possible to just do dotnet run -f net11.0 --project sample.csproj, and you'll get a list of simulators to choose from.

This is a variation of #24867.
