## Discussion

This property value is <doc://com.apple.documentation/documentation/Swift/true> if you initialized the asset with the [`AVURLAssetPreferPreciseDurationAndTimingKey`](/documentation/AVFoundation/AVURLAssetPreferPreciseDurationAndTimingKey) initialization option, otherwise it’s <doc://com.apple.documentation/documentation/Swift/false>.
