Save image file to app documents directory in Swift. Does the url to App document directory change even when deployed on the device?

Question

Below are the two functions which I use in the picker view controller to save the file in the App documents directory. And save the url in the local DB & display the image using UIImage(contentsOfFile: ImagePathString)

Everything works well as until this point however as soon as i re-run the simulator images does not show up. I believe its because the app directory keeps changing every time its run on the simulator. My question if its the same when deployed on the device?

 func getDocumentsDirectory() -> NSString {
    let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
    let documentsDirectory = paths[0]
    return documentsDirectory
}

    //Below function is used in imagePickerController

    if let data = UIImagePNGRepresentation(modifiedImage!) {
        let filename = getDocumentsDirectory().stringByAppendingPathComponent("\(NSDate()).png")
        data.writeToFile(filename, atomically: true)
        pathImage = filename
        print(pathImage)
    }

@HossamGhareeb Thank you. So its just in the simulator i would be facing issues displaying images when the app is rerun. — Kanan Jarrus, Apr 07 '16 at 06:23

Does it change every time the app is closed and reopned on the physical device after its deployed on it. – Kanan Jarrus Apr 07 '16 at 06:21
Not checked that. But it changes don't know when so use relative path. – Payal Maniyar Apr 07 '16 at 06:22
Yes, you should store just the path after document directory, in your example, just the file name, and retrieving it from document directory – FredericP Apr 07 '16 at 06:30
