Hey. I have only recently started looking at Swift and got to an issue I have previously solved in Objective C, but not in Swift.

The gist is that I want to declare a base class, then have many subclasses override a central method but with their own data types. For example:

class BaseCell {
    func setupCell(data: Any) {
        // Use subclasses
    }
}

Then a subclass that sets the cell up with a string could be

class TextCell: BaseCell {
    override func setupCell(text: String) {
        label.text = text
    }
}

And another could have an integer

class NumberCell: BaseCell {
    override func setupCell(number: Int) {
        label.text = number as String
    }
}

The way I then use them are like this (psuedo code)

// Data setup
//      cellType,   cellData
cells = NumberCell, 21
        NumberCell, 5
        TextCell,   "text"
        NumberCell, 12

// TableView cellForIndexPath
cell = getCellOfType(cellType)
cell.setupCell(cellData)

But right now as I cannot override the setupCell, I have to do this

override func setupCell(data: Any?) {
    labelVersion.text = data as? String
}

Any pointers?
