MTKTextureLoader.Callback

The signature for the block executed after an asynchronous loading operation for a single texture has completed.

Declaration

typealias Callback = ((any MTLTexture)?, (any Error)?) -> Void

Discussion

The block parameters are defined as follows:

texture

A MTLTexture object, or nil if an error occurred.

error

If the operation was successful, this value is nil; otherwise, this parameter holds an NSError object that describes the problem that occurred.
