Iterating through an array (Swift)

Question

I have an array, photoAsset, and I am trying to delete each item listed in the array from an asset collection. How do I go about doing this?

This is what I have tried

    PHPhotoLibrary.sharedPhotoLibrary().performChanges({ () -> Void in

        let request = PHAssetCollectionChangeRequest(forAssetCollection: self.assetCollection)

        //This is the number of items in my array
        println(self.photosAsset.count)

        //Only removes the FIRST item, need to remove ALL items
        request.removeAssets([self.photosAsset[0]])


        }, completionHandler: nil)

Why? The request array is defined in the scope of the block and will be released after its finished. Why remove them all? — Fogmeister

For the function of my app, the button is to remove all photos in the library. I could go into detail of the functionality of my app but that would be pointless. I figured out the answer and posted it if you are curious. — Josh O'Connor

What is in your self.photoAsset array? Are the elements PHAsset objects or arrays of PHAsset objects? — Paulw11

Why not request.removeAssets(self.photosAsset) rather than removing them one by one in a loop?

I feel like an idiot, completely forgot about a for loop smh... Here is the answer.

        let request = PHAssetCollectionChangeRequest(forAssetCollection: self.assetCollection)

        self.photosAsset.count
        for (var i=0; i<self.photosAsset.count; i++) {
        request.removeAssets([self.photosAsset[i]])
        }

        }, completionHandler: nil)
