Answer 1

What are you finding is `Protocol'. Interfaces are same as protocol in Swift.

protocol Shape {
    func shapeName() -> String
}

class Circle: Shape {
    func shapeName() -> String {
        return "circle"
    }

}

class Triangle: Shape {
    func shapeName() -> String {
        return "triangle"
    }
}

class and struct both can implements the protocol.
