Call Function of custom Swift Framework

Question

I'm trying to create a simple framework that has a function that returns "hello name" name being a passed argument. Below is the framework and code trying to call it.

Framework:

public class Greeter { public init () {} public static func greet(name: String) -> String { return "Hello /(name)." } }

Code:

import Greeter class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let greetingString: String = Greeter.greet("Bob") print(greetingString) } }

When I try typing out "greet("Bob")", what autocompletes is "(name: String) -> String greet(self: Greeter)". And when I manually type "greet("Bob")", I get the error: Instance member 'greet' cannot be used on type 'Greeter'; did you mean to use a value of this type instead?

You need to create an instance of Greeter class first and then call it's method.

let greeter = Greeter() let greetingString: String = greeter.greet(name: "Bob") print(greetingString)

Update: You don't need : String it's redundant here. So you can modify that line to:

let greetingString = greeter.greet(name: "Bob")

This works, but is there a way that I can do the same without creating an instance of the class (I've changed the function to be static)? I'm trying to follow Kilo Loco's video below youtube.com/watch?v=GMYxlkOE35k

Both are correct. If you make the method static then you could just call Greeter.greet()

Perfect, I just tried that and they both work! thank you so much!
