I am a bit lost someone please help with declaring a method.

Is method similar to a function if so am I doing this correctly and do I need so specify if the return value with will be a (String, String). Am I also able to use the constants in the struct as parameters in the function.

struct Person {
    let firstName: String
    let lastName: String

    func fullName()

Hi there! The only difference between a method and a function is that a method is part of the class/struct and defined inside it. All methods are functions, but only some functions are methods :smiley:

So yes, you will have to specify a return type. The same rules that apply to functions apply to methods as methods are simply a subset of functions.

Hope this helps! :sparkles:
