Various user interface elements you use to display your Metal content onscreen.

Topics

Metal Drawables

Render or write to a drawable and display it on the screen. Drawables are displayable resources available through either MetalKit or Core Animation.

protocol MTLDrawable

A displayable resource that can be rendered or written to.

protocol CAMetalDrawable

A displayable resource that can be rendered or written to by Metal.

MetalKit View

Use a specialized view, with an optional drawing delegate, to create a display-centric Metal app. Views are typically used to display graphics render targets, but may also be used to display the results of compute-processing tasks.

class MTKView

A specialized view that creates, configures, and displays Metal objects.

protocol MTKViewDelegate

Methods for responding to a MetalKit view's drawing and resizing events.

Core Animation Layer

Use a specialized backing layer to create a display-centric Metal app. Views are typically used to display graphics render targets, but may also be used to display the results of compute-processing tasks.

class CAMetalLayer

A layer that manages a pool of Metal drawables.
