Not able to build iOS binding library on Visual Studio (Windows) #23408
Description
Description
When creating an iOS binding library (using SwiftUI) there is no way to build it from a Windows device that is connected to a MAC. Always getting error: build a binding project from Windows unless a connection to a Mac is available (while connected to MAC)
On a MAC (with VSCode) the binding library works fine, using <XcodeProject... , when building the same project on Visual Studio (Windows) with a paired MAC there the project does not create good output, while is says the build succeeds.
When using MACCATALYST it gives a warning "It's currently not supported to build a binding project from Windows unless a connection to a Mac is available" but the build still succeeds. iOS doesn't give a warning at all.
The /bin output doesn't give proper output like a build on a MAC, ie: missing the @[email protected] folder with the SwiftUI project output.
Steps to Reproduce
- Create a very simple SwiftUI project
- Create a MAUI iOS binding project and implement the SwiftUI project, somthing like this:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFrameworks>net9.0-ios;net9.0-maccatalyst</TargetFrameworks>
<Nullable>enable</Nullable>
<ImplicitUsings>true</ImplicitUsings>
<IsBindingProject>true</IsBindingProject>
<IsTrimmable>true</IsTrimmable>
</PropertyGroup>
<ItemGroup>
<ObjcBindingApiDefinition Include="ApiDefinitions.cs" />
<ObjcBindingCoreSource Include="StructsAndEnums.cs" />
</ItemGroup>
<ItemGroup>
<XcodeProject Include=".\WidgetKitProxy\WKP.xcodeproj">
<SchemeName>WKP</SchemeName>
</XcodeProject>
</ItemGroup>
</Project>
- Run/Test on MAC > this works
- Run/Test on Windows (where VS is attached to MAC) > this gives error message
