Problems using screensaverdefaults

I want to save a variable defined from a dropdown in the preferences sheet to screensaverdefaults. Bools seem to save properly, but strings don't seem to save properly. i tried Database.standard.set(selectedVideo: "Choice") where choice is a string. But something just doens't work right. I can upload the entire project if it can help me, i'm quite new to swift development. Thanks in advance!

Added gists to some of the code: https://gist.github.com/MaxTechnics/394bb98e88f526de5b93b50efdfa4bcf https://gist.github.com/MaxTechnics/5527ede328595a63049e88ffa8f9c5f2

Solution

  • There is a mistake in getter selectedVideo:

        var selectedVideo: String {
        return String(Database.Key.selectedVideo)
    }

    This code just returns Key, not value.

    It's necessary to use string accessor UserDefaults.string(forKey:):

    func string(forKey defaultName: String) -> String?

    So the correct code should look like this:

        var selectedVideo: String? {
        return string(forKey: Database.Key.selectedVideo)
    }

    or this:

        var selectedVideo: String {
        return string(forKey: Database.Key.selectedVideo) ?? "default value"
    }
