PHFetchOptions Duration not working properly

I'm trying to fetch all the Videos which their duration is higher than 1.5 sec.

What i have tried

        let videoOptions = PHFetchOptions()
        let dur : Double = 1.5
        videoOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
        videoOptions.predicate = NSPredicate(format: "mediaType = %d AND duration > %d", PHAssetMediaType.Video.rawValue,dur)
        VideoCollectionFetchResult =  PHAsset.fetchAssetsWithOptions(videoOptions)

The docs says :

Any suggestions? Thanks!

Solution

  • It is related to the format - duration is actually Double format, and %d is for integer. Try to use %f, like: 

    (format: "mediaType = %d AND duration > %f", PHAssetMediaType.Video.rawValue,dur)
