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")
        }
    }

Saved Image in document directory and save path in coredata not able to fetch the image file iOS swift

Solution: If you saved the entire path like file://....png then it is not possible to get the image because document directory path will be dynamic.So better you can save the imagename in your coredata after that below code to get the image. Code: let documentsDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]       let urls = documentsDirectory.appendingPathComponent(filename) it will return the url of the image.You can get the image and enjoyyy....
