Nullable Int in Swift

I am attempting to use a hash that contains a nullable int as a value. The below is the code.

var facs:[(pk:Int,phone:Int?,name:String)] = []
var phone: AnyObject? = fac["phone"]!
var phoneLong:Int?;
if(phone == nil){
    phoneLong = nil
}
else{
    phoneLong = phone as? Int
}
var id = fac["id"]! as Int
var name = fac["name"]! as String

facs.append(pk:id, phone:phoneLong, name:name)

However, I get a compile error on the facs.append line that states Type 'T' does not conform to protocol 'IntegerLiteralConvertible'. I've tried a few variations, and the only way I can get rid of the error is to make phone a non-nullable int, which is not what I need. Thoughts?

Solution

  • It looks like the append method doesn't correctly detect the parameters as a tuple - just make that explicit by assigning the tuple to a variable:

    let params = (pk:id, phone:phoneLong, name:name)
facs.append(params)
