The Big Nerd Ranch Swift - Ch.25 Gold Challenge

There is no description of challenge. Becaouse of license.

When I use a header “class someName…” in code block for some code, that means the following code is within the scope of the class named ‘someName’.

It is similar to ch24 Bronze Challenge. I went ahead… Creat Person Class and have it conform Equatable Protocl. and implement == method.

class Person: Equatable {
    
    var name: String
    var age: Int
    
    init(name: String, age: Int) {
        self.name = name
        self.age = age
    }
    
    static func == (lhs: Person, rhs: Person) -> Bool {
        return ( lhs.name == rhs.name ) && ( lhs.age == rhs.age )
    }
}

And test it

let p1 = Person(name: "p1", age: 1)
let p2 = Person(name: "p2", age: 2)
var people = [p1, p2]
let p1Index = people.firstIndex(of: p1)  // 0
