Easily compare two objects by using KeyPath

Equatable+CheckIfEqualTo.swift

extension Equatable {
    func checkIfEqualTo<T: Equatable>(_ other: Self, byComparing paths: KeyPath<Self,T>...) -> Bool {
        for keyPath in paths {
            guard self[keyPath: keyPath] == other[keyPath: keyPath] else {
                return false
            }
        }
        return true
    }
}
