You can save the image name or URL in `UserDefaults` and fetch it from there when user opens the app — S1LENT WARRIOR, Apr 19 '20 at 16:34

You can save the image name or URL to UserDefaults.
Here is a code snippet to save URL string to UserDefaults.

UserDefaults.standard.set(avatarUrl, forKey: "userAvatar")

And retrieve the URL when displaying the image.
Something like this:

UserDefaults.standard.object(forKey: "userAvatar") as? String

You can also create a property in a class or struct by combining the above approaches to save/retrieve a property to/from UserDefaults.
for example:

var userAvatar = UserDefaults.standard.object(forKey: "userAvatar") as? String {
    didSet {
        UserDefaults.standard.set(avatarUrl, forKey: "userAvatar")
    }
}

Now you can use this property to save or load the image URL string using UserDefaults.

Hope this helps

Thats a separate question. But there are various ways to load image from a `URL`. I think this thread might be helpful for you. https://stackoverflow.com/questions/24231680 — S1LENT WARRIOR, Apr 20 '20 at 13:19
