@backDeployed(before: macOS 15, iOS 18, tvOS 18, watchOS 11, visionOS 2)
final func insertTimeRange(_ timeRange: CMTimeRange, of asset: AVAsset, at time: CMTime, isolation: isolated (any Actor)? = #isolation) async throws

Inserts all the tracks of a timeRange of an asset into a composition. - Parameters: - timeRange: Specifies the timeRange of the asset to be inserted. - asset: Specifies the asset that contains the tracks that are to be inserted. Only instances of AVURLAsset and AVComposition are supported. - time: Specifies the time at which the inserted tracks are to be presented by the composition. - isolation: The actor isolation for accessing non-Sendable values. Inherits the calling isolation by default.
