This is my code:

    required convenience init?(coder aDecoder: NSCoder) {



    // The name is required. If we cannot decode a name string, the initializer should fail.

    guard let name = aDecoder.decodeObject(forKey: PropertyKey.name) as? String else {

        os_log("Unable to decode the name for a Savings object.", log: OSLog.default, type: .debug)

        return nil

    }



    // Because photo is an optional property of Savings, just use conditional cast.

    let photo = aDecoder.decodeObject(forKey: PropertyKey.photo) as? UIImage



    let savingsAmount = aDecoder.decodeObject(forKey: PropertyKey.savingsAmount)



    let amountSavedPerWeek = aDecoder.decodeObject(forKey: PropertyKey.amountSavedPerWeek)



    let amountSavedSoFar = aDecoder.decodeObject(forKey: PropertyKey.amountSavedPerWeek)



    // Must call designated initializer.

    self.init(name: name, photo: photo, savingsAmount: savingsAmount as! String, amountPerWeek: amountSavedPerWeek as! String, amountSavedSoFar: Int)



}



func encode(with aCoder: NSCoder) {

    aCoder.encode(name, forKey: PropertyKey.name)

    aCoder.encode(photo, forKey: PropertyKey.photo)

    aCoder.encode(savingsAmount, forKey: PropertyKey.savingsAmount)

    aCoder.encode(amountPerWeek,forKey: PropertyKey.amountSavedPerWeek)

    aCoder.encode(amountSavedSoFar, forKey: PropertyKey.amountSavedSoFar)

}

On this line:

self.init(name: name, photo: photo, savingsAmount: savingsAmount as! String, amountPerWeek: amountSavedPerWeek as! String, amountSavedSoFar: Int)

properties
var name: String
var photo: UIImage?
var savingsAmount: String
var amountPerWeek: String
var amountSavedSoFar: Int

I get the error Cannot convert value of type 'Int.Type' to expected argument type 'Int'. I can't seem to figure the fix to this, the only time the error came up was when I added the type "Int". Thanks for the help.

You have this (I added line breaks to make it easier to read):

self.init(name: name,

          photo: photo,

          savingsAmount: savingsAmount as! String,

          amountPerWeek: amountSavedPerWeek as! String,

          amountSavedSoFar: Int)

but I think you meant to type this:

self.init(name: name,

          photo: photo,

          savingsAmount: savingsAmount as! String,

          amountPerWeek: amountSavedPerWeek as! String,

          amountSavedSoFar: amountSavedSoFar as! Int)

Basically, you forgot to pass in the local variable amountSavedSoFar and instead just typed Int, so the compiler thinks you're trying to pass in the type Int itself as the parameter, which is why you're getting that error.

Also, one unrelated thing, I find it interesting that if name is not able to be decoded, then you return nil, but then if savingsAmount, amountPerWeek, or amountSavedSoFar cannot be decoded then you've opted to crash the app by using the "crash here" operator, as!. You may also want to return nil if any of those can't be decoded either.
