How to create a dynamic string in Swift?

Question

What I want to know is how to create in swift a string with notation on localizable file and replace this notation just before.

"welcome" = "Hello %@, Welcome!"
"seeYou"  = "Goodbye %@"
"update"  = "All your profile data was update, %@"

in another file:

func showMessage(name : String){
  print(welcome,name)
}

thanks for the help,

Filipe

let *name = "Filipe" var welcome = "Hello \ (name), Welcome!" print("result is :\ (welcome )") — Gagan_iOS, Oct 30 '15 at 17:50

It's much easier in Swift than in Objective-C by using String Interpolation

let name = "Filipe"
print("Hello \(name), Welcome!")

or the plus operator

print("Hello " + name + ", Welcome!")

In an environment to process localizable strings use

let welcome = "Hello %@, Welcome!"

func showMessage(name : String){
  print(String(format: NSLocalizedString(welcome, comment: ""), name))
}

showMessage("Filipe")

`print`also supports this now: `print("Hello", name, ", Welcome!")` String doesn't :( – R Menke Oct 30 '15 at 17:52
Yes, but you'll get an unwanted space character after the `name` variable in this example. – vadian Oct 30 '15 at 17:58

You can do this:

func showMessage(name : String) {
    let msg : String = String(format: "Hello %@, Welcome!", name)
    print(msg)
}
