"Debug|iPhoneSimulator" disappeared in Visual Studio for Mac

[arivoir]

I'm trying to run a Xamarin.iOS project in Visual studio for Mac, but the "Debug|iPhoneSimulator" configuration is not available, only "Debug" and "Release" appear

When inspecting the "Options" of the solution I see the configurations are there

Unfortunately the Debug configuration doesn't run

MTOUCH: Error MT0074: Xamarin.iOS 13.10.0 does not support a deployment target of 13.3 for iOS (the maximum is 13.2). Please select an older deployment target in your project's Info.plist or upgrade to a newer version of Xamarin.iOS. (MT0074) (Test2)

I tried downloading previous simulators from Xcode, but they don't appear either.

The issue is reproducible creating a blank project.

Thank you for your feedback!

For us to investigate this further, could you please provide a test case (to reproduce) and all your version information.

The easiest way to get exact version information:

• On Visual Studio for Mac: "Visual Studio" menu, "About Visual Studio" item, "Show Details" button.
• On Visual Studio for Windows: "Help menu", "About Microsoft Visual Studio" item.

Then copy/paste the version information (you can use the "Copy Information" button).

I suspect that your solution is misconfigured, but without an example it is difficult to determine what's going on.

We look forward to hearing from you!

The repro steps are the following

• Open Visual Studio for Mac.
• Create New Project.
• Choose Single iOS App.
• Enter Name and press "Create".
• Open configuration combo box and only "Debug" and "Release" are present.

Here is the solution file

[chamons]

I believe this is expected behavior and not a bug. We no longer swap between Sim and Device here:

but in the second device button here:

Does that make sense? If not, please explain what exactly is broken.

[arivoir]

In that case there are 2 bugs.

1. Some projects are actually loading the "Debug|iPhoneSimulator" in the vs4mac first combobox

2. There is something that doesn't allow the projects to build. Neither the default project created with the default project is working.
   The building error is the following

/Users/alvaror/Projects/Test3/MTOUCH: Error MT0074: Xamarin.iOS 13.10.0 does not support a deployment target of 13.3 for iOS (the maximum is 13.2). Please select an older deployment target in your project's Info.plist or upgrade to a newer version of Xamarin.iOS. (MT0074) (Test3)

I suspect this error is because the incorrect configuration is loaded somewhere.

[arivoir]

I forgot to mention that the same projects that aren't building in vs4mac build fine in vs4win

[chamons]

On this:

    /Users/alvaror/Projects/Test3/MTOUCH: Error MT0074: Xamarin.iOS 13.10.0 does not support a deployment target of 13.3 for iOS (the maximum is 13.2). Please select an older deployment target in your project's Info.plist or upgrade to a newer version of Xamarin.iOS. (MT0074) (Test3)

This is actually only half a bug, as our release notes document:

Xcode 11.3 doesn't ship an iOS/tvOS 13.3 SDK, therefore the maximum deployment target remains 13.2

The IDE shouldn't suggest 13.3, but Xcode doesn't ship a 13.3 SDK with Xcode 13.3, only 13.2

Changing your info.plist to 13.2 will solve that.

On the other one, if you can attach a project showing that, I'll pass it on to the IDE folks for consideration.

[arivoir]

The problem in the default template project is the default target is 13.3, changing it to 13.2 works. It's weird a newest version exist and appear but it doesn't work.

The I found a series of problems that apparently are unrelated, but strangely only apear in vs4mac, and were working in previous versions.

Some projects had the following code

  <PropertyGroup Condition=" '$(OS)' == 'Unix' ">
    <CscToolExe>mcs.exe</CscToolExe>
  </PropertyGroup>

This was because it was needed when vs4mac just appeared. Now this provokes a building error

Error CS1617: Invalid -langversion option 7.3'. It must be ISO-1', `ISO-2', Default, Latest or value in range 1 to 7.2 (CS1617) (C1Gauge101)

When a project doesn't have a <OutputPath> set for the current configuration it doesn't allow to build in vs4mac

[chamons]

Please don't set CscToolExe unless absolutely necessary, we've been using csc for a number of releases, and mcs is not tested or significantly maintained.

And yes, we expect OutputPath to be set to have a sane build. You may want to compare your hand edited csproj files to a new project and see what settings you have that are no longer necessary.

If after that you are still having issues, please attach an example project.

[arivoir]

I think we don't need CscToolExe anymore, it was needed a time ago and remained in a set of samples.

Everything is running fine now. Anyway I don't understand how the first configuration combobox is populated in vs4mac. In some cases there is only "Debug" and "Release" but in others are a long list. What should I expect to see there?

[chamons]

I'm not honestly sure why it shows it differently. I'm asking around now.

However, they both should work even if the UX is different.

[chamons]

I'm not sure why the differences in UX, I have not heard back. Would you like me to convert this to a IDE bug to request more, or should I consider this closed @arivoir ?

[chamons]
