Get an image from it's name from Document directory iOS swift

-
Solution:

 If you saved an image to document directory in your app you cannot have to save the full url path to your database or coredata.

Because every time document directory path will be modified.So you can save the image name in your database and fetch it later using the below code.


func getImage(name:String)->UIImage{
        let fileManager = FileManager.default
        let imagePAth = (NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as NSString).appendingPathComponent(name)
        if fileManager.fileExists(atPath: imagePAth){
            if UIImage(contentsOfFile: imagePAth) != nil{
                return UIImage(contentsOfFile: imagePAth)!
            } else{
                return  imageLiteral(resourceName: "default image you saved")
            }
        }
        else{
            return  imageLiteral(resourceName: "default image you saved")
        }
    }
