where should I write the function?

Hi guys

I have a question which I always stumble upon. Say you have two structures as follows:

Code:

struct Occupation {

    let name: String

}


struct Person {

    let firstName: String

    let lastName: String

    var occupations: [Occupation]

    func hasAnOccupationOfKind(occupation occupationToMatch: String) -> Bool{

        var match = false

        for occupation in occupations {

            if occupation.name == occupationToMatch { match = true}

        }

        return match

    }
}

Should the function be coded in Person or within Occupation? Of course it would be named something like isOfKind(_ occupation: String)

Tx!
