Discussion

Call this method from an asynchronous context to load the value of one or more media properties. The method returns a single result if you load one property value, and returns a tuple if you load multiple properties (up to eight) at the same time.

To load a property, pass one or more AVAsyncProperty constants to this method as shown below.

// Load an asset's list of tracks.
let tracks = try await asset.load(.tracks)
        
// Load an asset's suitability for playback and export.
let (isPlayable, isExportable) = try await asset.load(.isPlayable, .isExportable)
