Replacement for array's indexOf(_:) method in Swift 3

Question

In my project (written in Swift 3) I want to retrieve index of an element from array using indexOf(_:) method (existed in Swift 2.2), but I cannot find any replacem

Answer 1

This worked for me in Swift 3 without an extension:

struct MyClass: Equatable {
    let title: String

    public static func ==(lhs: MyClass, rhs: MyClass) -> Bool {
        return lhs.title == rhs.title
    }
}
