How do I concatenate strings in Swift?

Question

How to concatenate string in Swift?

In Objective-C we do like

NSString *string = @\"Swift\";
NSString *resultStr = [string stringByAppen         


        

Answer 1

It is called as String Interpolation. It is way of creating NEW string with CONSTANTS, VARIABLE, LITERALS and EXPRESSIONS. for examples:

      let price = 3
      let staringValue = "The price of \(price) mangoes is equal to \(price*price) "

also

let string1 = "anil"
let string2 = "gupta"
let fullName = string1 + string2  // fullName is equal to "anilgupta"
or 
let fullName = "\(string1)\(string2)" // fullName is equal to "anilgupta"

it also mean as concatenating string values.

Hope this helps you.
