Concatenate String and Integer in Swift

Question

I would have expected concatenation between different types to be straightforward in Swift, but apparently not. What is the workaround for this?

var boy = "Bart Simpson"
var age = 7
print(boy + " is " + age)

Answer 1

very easy, wrap all printable objects in \( )

let boy = "Bart Simpson"
let age = 7
print("\(boy) is \(age)")
