iOS Build Succeeds but NewBindingMaciOS Namespace Not Found in MainPage.xaml.cs

### Description

When building the project, the build succeeds and the framework is generated. However, when trying to use the iOS binding in [MainPage.xaml.cs] I get the following error is `The type or namespace name 'NewBindingMaciOS' could not be found (are you missing a using directive or an assembly reference?)`

### Steps to Reproduce

1. Build the solution, including the NewBinding.MaciOS.Binding project.
2. Build the Maui project.
2.In the Maui project (e.g., MainPage.xaml.cs), add the following code:
```
#if IOS || MACCATALYST
using NewBinding = NewBindingMaciOS.DotnetNewBinding;
#endif
```
```

```
Please advise how to ensure the iOS binding is correctly referenced and available in the Maui project.
