I'm trying to divide in this case 5/10 using NSExpression but it returns 0 instead of 0.5.

let expn = NSExpression(format:"5/10")

let answer = expn.expressionValueWithObject(nil, context: nil) as? NSNumber

And Ideas?

NSExpression is very restricted and that is one of its limitations. – Martin R Sep 18 '15 at 08:12
NSExpression is a Foundation class. The question and its answers are independent of whether you use it from Objective-C or Swift. – Martin R Sep 18 '15 at 08:14
