[iOS] Settings for Hotspot Hints in Preview Mode
When you tap anywhere on the screen while in the preview mode, the location of all hotspots are highlighted in blue.
1. To turn these off and preview your project more like a real app, go to “Share” under “Edit project”.
2. Deselect "Highlight active taps” and anyone who views your prototype in the preview mode by downloading it from the share URL will not see any blue highlighted areas.
