Multiple "newValue" values?

Is it possible to set multiple values for a setter of computed property? If so, how to do it since I only have one "newValue" ?

Hi Szymon,

Can you provide us with an example of what the outcome would look like? So that we could recommend other options.

Well, for instance:

set { self.width = newValue self.height = newValue2 //<--- How to use more than one newValue ? }

You can't do that but you could do something crazy like

class Table {
    var width: Int
    var height: Int

    var widthTwo: Int
    var heightTwo: Int

    init(width: Int, height: Int, widthTwo: Int, heightTwo: Int) {
        self.width = width
        self.height = height
        self.widthTwo = widthTwo
        self.heightTwo = heightTwo
    }
}

//Then 

var myTable = Table(width: 5, height: 5, widthTwo: 10, heightTwo: 10)

    myTable.width
    myTable.height

    myTable.widthTwo
    myTable.heightTwo

Not sure that this would help

No, you can't, Swift doesn't allow you to have multiple newValue for a setter of computed property.
