5,311 PointsString interpolation with functions and strings
Why does this return "John Smith":
func fullName(firstName: String, lastName: String) -> String {
return firstName + " " + lastName
}
fullName("John", "Smith")
but this returns errors such as 'Unresolved Identifier':
func fullName(firstName: String, lastName: String) -> String {
return firstName + " " + lastName
}
println("Your full name is \(fullName("John", "Smith"))")

Courses Plus Student 16,527 Points@Frances Angulo You can't call the function directly. If you want to use string interpolation, I suggest that you create a variable and assign the function on it. Then you can use it without error.
Example:
var fullname = fullName("John", "Smith")
println("Your full name is \(fullname)")
I hope this helps ;D

5,311 PointsThanks! This helped, I just didn't want to create the separate line of code. It looks like I can indeed call it in one line, but the interpolation escape character is not necessary.
This worked:
println("Your name is " + fullName("Frances", "Angulo"))Khairul Akmal

Courses Plus Student 16,527 PointsFrances Angulo No worries! I'm glad to help and that works too. Like I said if you want to use the string interpolation, that's how it should be done ;D
