When GPU Frame Capture is enabled, a frame can be defined as the code executed between calls to the
insert method, where each call is a frame boundary. If your app does not call this method, a frame boundary is instead defined by a call to the
present(_: method. If both methods are called, Xcode captures only the frame between
insert method is useful for defining your own frame boundaries. For example, an app with a single drawable and implicit frame boundaries may not need this method; however, an app with multiple drawables may benefit from explicit frame boundaries.
