Can somebody explain me how to add an instance method to the struct definition for this task ?
struct Person {
let firstName: String
let lastName: String
func getFullName(firstName: String, lastName: String) -> [Person]
{
let fullName = "\(firstName) \(lastName)"
return fullName
}
}
getFullName("Pradeep", lastName: "Chandrasekaran")

You have to first create an instance of the struct Person, that's what happens in my constant "myPerson" and you have to send the parameters for firstName and lastName.
After that, you only have to call your getFullName method, and you don't have to send again the parameters because you have already access to them since you have initialized your struct myPerson.
Here you are the answer:
struct Person {
let firstName: String
let lastName: String
func getFullName() -> String {
let fullName = "\(firstName) \(lastName)"
return fullName
}
}
let myPerson = Person(firstName: "Pradeep", lastName: "Chandrasekaran")
myPerson.getFullName()

If you are not going to use the variable elsewhere in the functions body, it doesn't make sense to create one. Just return the desired result directly.
