images from library have wrong order

[sergJozee]

When i pick images from the library i do not get the images to show in the correct order. The first image i pick from library does not always show as first image in the list with chosen images.

@sergJozee I met the same problem. I pick the according index using enumerated()

@sergJozee @DesmondDAI Could you post your code about show chosen images?

I tried to multi select photos:

let pickerController = DKImagePickerController()
pickerController.assetType = .AllPhotos
pickerController.showsCancelButton = true
pickerController.maxSelectableCount = 5

pickerController.didSelectAssets = { (assets: [DKAsset]) in
    for (index, asset) in self.selectedImageAssets.enumerate() {
        asset.fetchImageWithSize(CGSizeMake(512, 512), options: getImageRequestOptions(), contentMode: PHImageContentMode.AspectFill, completeBlock: {
            (image, info) in
            print("index: \(index)")
        })
    }
}

And the function getImageRequestOptions():

private func getImageRequestOptions() -> PHImageRequestOptions {
    let options = PHImageRequestOptions()
    options.deliveryMode = PHImageRequestOptionsDeliveryMode.HighQualityFormat
    options.networkAccessAllowed = true
    return options
}

The printed index is out of order. e.g. 3 1 2 0

Hi @DesmondDAI
The fetchImageWithSize is an asynchronous method. It will get images from your device or iCloud, so the callback order is not guaranteed.

Update: using this method and then it should work well.
public func fetchFullScreenImage(sync: Bool, completeBlock: (image: UIImage?, info: [NSObject : AnyObject]?) -> Void)
