How to Typecast Obligation is Apple Swift?

Anonymous User 1625 17-Oct-2014

Am I missing something or typecast is obligatory while adding numbers having different types:

var i:Int=5

var d:Double=6.0

var q:Double= i + d

var w:Double= Double(i) + d

Swift doesn't provide automatic conversion between numeric types.

Normally you just perform conversions like you used in your question.

I don't recommend it, but you could do this:

func +(i:Int, d:Double) -> Double {
    return Double(i) + d
}
let i: Int = 1
let d: Double = 7.0
i + d
// result: 8.0

You would need to provide a lot of overrides to cover all the bases. Like I said, I don't recommend it.
