Save UIImage array in NSUserDefaults

Question

I want to put a UIImage array into UserDefaults and then retrieve it. After that set the retrieved images in an image view. How can I do that?

That's really bad idea if you really going to do that. You should save image in DocumentDirectory and save images name in NSUserDefaults.

func saveImages(images:[UIImage]) {

     let fileManager = FileManager.default
     let path = (NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as NSString) 
     var imagesNames = [String]()


    do {

        if !fileManager.fileExists(atPath: path as String){
            try fileManager.createDirectory(atPath: path as String, withIntermediateDirectories: true, attributes: nil)
        }

     for (index,image) in images.enumarated() {
        let imageName = "Image\(index).jpg"
        let imageData = UIImageJPEGRepresentation(image, 1.0)
        if fileManager.createFile(atPath: paths.appending("/\(file)") as String, contents: imageData, attributes: nil) {
         imagesNames.append(imageName)
        }
      }
     let storage = UserDefaults.standard
     storage.set(imagesNames, forKey: "imagesArray")
     storage.synchronize()

    }catch{
        //Throw Error
    } 
}
