D8: Missing Geofield Proximity Field in View

I am missing expected proximity field & filter in Views.

I am following this Basic Dealer Locator tutorial but instead of D7 I am using:
Drupal 8.2.0
Geofield 8.x-1.0-alpha2
Geocoder 8.x-2.0-alpha4

I am successfully populating the geofield on my content type. However, on a view there is no [geofield] – proximity field nor the proximity filter to expose. There is only the geofield point to display.

D7 tutorials seem to suggest these proximity fields should just appear with a geofield field. But this isn’t happening for me. Am I missing a step? A module?

Any idea why I am not seeing the proximity in views?

Thanks,
Polly

Update

I found this issue on geofield: Re-implement the Views proximity filter/field for Drupal 8. Does this issue explain my problem?

The patch fails:

I am a patch novice. Am I applying it incorrectly?
