## Return Value

Return Value The loaded property value.

## Discussion

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)
