present()
Presents the updated texture to the renderer as soon as possible.
Declaration
func present()Discussion
Needs to be called after all commands in the command buffer have been executed (e.g. after MTLCommandBuffer.waitUntilCompleted()). When you call this method, the drawable will make the new texture content available to the renderer immediately.
Alternatively, instead of waiting for completion you can call MTLCommandBuffer.present(_:) to signal in the command buffer that the texture is ready to use.
