String to decimal swift

Question

I am using userdefaults to save a decimal value of unknown length ( I.e. 51000000000) . Userdefaults does not allow for the saving of long decimal numbers, so I resorted to turning the value into a string and saving it. Then I want to re load the number however I have been unable to find a way to convert string value into a decimal. How do I do this?

Edit:

Code for setting the value into userdefaults:

let savedValues = UserDefaults.standard
savedValues.setValue(String(describing: buildingConstants.jitterClickConstantCost), forKey:"jitterClickCost")

struct buildingConstants {
     static var jitterClickConstantCost = Decimal()
}

You can try the default initializer for Decimal with a string parameter

here is an example

let decimal: Decimal = 51000000000
let str = String(describing: decimal)

let savedValues = UserDefaults.standard

savedValues.set(str, forKey:"jitterClickCost")
savedValues.synchronize()

let value = savedValues.string(forKey: "jitterClickCost") ?? "0"

let result = Decimal(string: value)
