I can confirm also and even my position is not displayed.

[amay077]

I can see location button on iOS by below code with v2.2.1-beta1 and XFGoogleMapsSample.

    public partial class BasicMapPage : ContentPage
    {
        public BasicMapPage()
        {
            InitializeComponent();

            map.UiSettings.MyLocationButtonEnabled = true;
        }
    }

A was testing on android emulator and it is not showing with the same code

[amay077]

Thanks. I reproduced it. (I didn't run on Android because this issue is about iOS side)

A was testing on android emulator and it is not showing with the same code

This issue has 2 reasons.

1. Design of GoogleMaps Android API - We should set Map.MyLocationEnabled = true and UiSettings.MyLocationButtonEnabled = true for display location button.
2. Bug - Map.MyLocationEnabled = true in page constructor is not worked. This is my bug.

Conclusion

Add map.MyLocationEnabled = true in your page constructor.
And wait for next version(v2.2.1-beta2).

public partial class BasicMapPage : ContentPage
{
    public BasicMapPage()
    {
        InitializeComponent();

        map.MyLocationEnabled = true;  // <-- added
        map.UiSettings.MyLocationButtonEnabled = true;
    }
}
