My WatchKit wkinterfacetable won't scroll

Tables don't behave properly when nested within a group. Remove the group and your tableview should scroll.

The HIG also mentions not to do this: https://developer.apple.com/watch/human-interface-guidelines/ui-elements/

My one wasn't scrolling because I had "Fixed to screen edges" enabled in the storyboard for that interface controller. Make sure you have that disabled.
