The state change gesture allows activating a link when a behavior reaches a specified state. This can be used to create things like a loading indicator where the completion of the loading indicator triggers a transition to another screen.

Use the state change gesture type

• Create a link originating from a behavior group. This gesture type will not be available to choose unless the link is created from a group that has a behavior applied to it.
• Choose "State Change"
• Choose a target state from the popover or the gesture inspector

The link will be activated when the behavior reaches the specified state.
