[iOS/Mac Catalyst] ApplicationTitle is not setting correctly

Summary

We have several .NET MAUI Blazor projects and we're going to be publish them in Apple store but the <ApplicationTitle>Bit BlazorUI Demo</ApplicationTitle> is not setting correctly!

• In iOS's home screen spaces of title ignored and shows BitBlazorUIDemo but like in the remove app popup or applications list it shows fine.
• In Mac Catalyst it uses the csproj name for execute file which is Bit.BlazorUI.Demo.Client.App and because the end of it has App word it won't show up in Launchpad.

Can you create a project with what values you tried to change and where to reproduce what your screenshots show? It'll help so we can know exactly what you tried to change.

@drasticactions which area should I move this issue to? Doesn't seem to be Blazor specific.

Yeah, it's not related to Blazor @mkArtakMSFT

I think @jsuarezruiz should replace Blazor label with Mac Catalyst.

@drasticactions Will it be fixed in .NET 8 GA? because I'm on RC1 and the MacCatalyst app name issue is still there!

We have the same issue when setting the in the csproj file with a space between two words. On iOS the space is then missing.

Does anybody has a workaround?

Verified this issue with Visual Studio for mac 17.6.8 (build 400). Can repro on iOS platforms with sample project. MauiAppTitleIssue.zip

Another fun tidbit. If the assembly name has spaces in it, it breaks debugging. A simple condition to the property fixes that.

For iOS, the removal of spaces is intended behavior per https://stackoverflow.com/questions/44275567/how-can-i-add-spaces-to-the-app-name

This is kind of interesting, on iOS the name of the app bundle isn't visible anywhere for the end user, while for Mac Catalyst it's apparently quite visible.

Should we come up with a public MSBuild property for this? And then .NET MAUI's $(ApplicationTitle) could also set it?

Seems like just making _AppBundleName default to $(ApplicationTitle) for Mac Catalyst (and macOS as well I suppose) in our props file would do it.

Moving to xamarin/xamarin-macios, because that's where this should be fixed.

Workaround (from #21478):

1. Pass -p:_AppBundleName="Actual App Title" to dotnet publish.
2. Set CFBundleExecutable=Actual App Title in the Info.plist.
3. Pass -bl:msbuild.binlog to dotnet publish as well, and upload msbuild.binlog if it still doesn't work.
