Get a Swift Variable's Actual Name as String

Question

So I am trying to get the Actual Variable Name as String in Swift, but have not found a way to do so... or maybe I am looking at this problem and solution in a bad angle.

Answer 1

I've come up with a swift solution, however unfortunately it doesn't work with Ints, Floats, and Doubles I believe.

func propertyNameFor(inout item : AnyObject) -> String{
    let listMemAdd = unsafeAddressOf(item)
    let propertyName =  Mirror(reflecting: self).children.filter { (child: (label: String?, value: Any)) -> Bool in
        if let value = child.value as? AnyObject {
            return listMemAdd == unsafeAddressOf(value)
        }
        return false
        }.flatMap {
            return $0.label!
    }.first ?? ""
    
    return propertyName
}

var mutableObject : AnyObject = object
let propertyName = MyClass().propertyNameFor(&mutableObject)

It compares memory addresses for an object's properties and sees if any match. The reason it doesn't work for Ints, Floats, and Doubles because they're not of type anyobject, although you can pass them as anyobject, when you do so they get converted to NSNumbers. therefore the memory address changes. they talk about it here.

For my app, it didn't hinder me at all because I only needed it for custom classes. So maybe someone will find this useful. If anyone can make this work with the other datatypes then that would be pretty cool.
