In programming its very common to display output on screen. Swift provides a very handy built-in function called println().
println("Hello from Swift")
You can print different variables with println function.
var myName = "Khan" println(myName)
You can also print your string with variable at same time. To achieve this task you need two things one is back-slash ‘\’ and second is small brackets ‘( )’. This technique is called string interpolation.
var myName = "Khan" var country = "Sweden" var myPostCode = 12345 println("My Name is \(myName), i live in \(country) and my postcode is \(myPostCode)")
