Swift version: 5.6
Swift offers three different ways of joining strings. The first is using the +
operator to join two strings to make a third:
let string1 = "Hello, "
let string2 = "world"
let combined1 = string1 + string2
The second is user string interpolation to make a new string”
let combined2 = "\(string1) \(string2)"
The last is using the +=
operator to add and assign a string to an existing string:
var combined3 = "Goodbye, "
combined3 += "cruel world"
