I want to use Concurrent, stream based similarity search but don't understand how to do that.

I want to use Concurrent, stream-based similarity search for finding similar images from all images in the phone gallery but I cannot understand how to do that. I have tried to use an array-based method but that takes too long to get all the image data in an array and causes memory management issues. If anyone knows this please help me.

You can try the following in the project's playground:

var names = ["blurred_architecture1.bmp", "compressed_architecture1.jpg", "blurred_architecture_2.bmp", "compressed_architecture_2.jpg"]
let similarImages = imageHashing.similarImages(withProvider: .pHash) { () -> OSTuple<NSString, NSData>? in
   if names.count > 0 {
       let name = names.removeFirst()
       let url = Bundle.main.urlForImageResource(NSImage.Name(name))!
       let data = try! Data(contentsOf: url)
       return OSTuple<NSString, NSData>(first: name as NSString, andSecond: data as NSData)
   } else {
       return nil
   }
}
print("Images", similarImages)
