I'm not sure if this is possible, but I have a view that is able to be dragged around the screen via pan gestures. Once the view is selected, little grippers appear on the corners of the view that allow the user to resize the view. The problem is, those grippers go outside the bounds of the view (they still show up, because clipSubviews is off), but gesture recognizers on those grippers are not firing when selecting the part of them that is drawn outside of the view. Making the view bigger to actually hold the grippers would break a lot of already created logic that is based on the size of the view, so that is a last resort for me.
Is there any other way to get gesture recognizers to work on views that are drawn outside of their parent view?

A pan gesture occurs any time a person moves one or more fingers around the screen. A screen-edge pan gesture is a specialized pan gesture that originates from the edge of the screen. Use the UIPanGestureRecognizer class for pan gestures and the UIScreenEdgePanGestureRecognizer class for screen-edge pan gestures.
UITapGestureRecognizer is a concrete subclass of UIGestureRecognizer . For gesture recognition, the specified number of fingers must tap the view a specified number of times. Although taps are discrete gestures, they're discrete for each state of the gesture recognizer.
The tap gesture recognizer appears in the Document Outline on the left. We need to implement an action that defines what happens when the user taps the image view. Open ViewController. swift and define a method with name didTapImageView(_:) . It accepts the tap gesture recognizer as its only argument.
You could try overriding hitTest:withEvent: in a UIView subclass, and return the gripper view.
