override func in class swift - swift

Question

I am quite new to swift and I have a question regarding the definition of functions in a class.
I want to generate several items and give each of them a special function so I can run them by itemxy.useitem()
class item {
var name = "test"
func useitem(){
print("test")
}
}
let staff = item()
staff.name = "Staff"
staff.useitem() // prints: test
*override staff.useitem() = {print("this is a staff")}*
staff.useitem() // prints: this is a staff
how can I align a new function to my item staff?

Answer 1

These are not entirely swift related and are more general programming, you wont get your answers to such problems here. You should read up on basic programming principles before you tackle things further.
Having said that your problem is easily solved with Inheritance or Protocols.
Inheritance
class Item {
var name: String
init(name: String) {
self.name = name
}
func use() {
print("using a \(name)")
}
}
class Hat: Item {
override func use() {
print("I put on a \(name)")
}
}
class Pen: Item {
init() {
super.init(name: "Pen")
}
}
let pen = Pen()
pen.use()
let hat = Hat(name: "Beanie")
hat.use()
Protocol
protocol Item {
var name: String { get set }
func use()
}
extension Item {
func use() {
print("using a \(name)")
}
}
struct Pen: Item {
var name: String
init() {
self.name = "Pen"
}
}
struct Hat: Item {
var name: String
func use() {
print("I put on a \(name)")
}
}
let pen = Pen()
pen.use()
let hat = Hat(name: "Beanie")
hat.use()
