I don't think so. Mobile development is almost more about the underlying frameworks than the language itself. At some point Kotlin etc will have to wrap these things. The internal apple swift dev team will always be one step ahead of them as they will have access to the new frameworks before they are released to the public. Also swift and kotlin are very similar. The folks from kickstarter gave a great presentation about their android/iOS app being written in Swift/Kotlin at a conference I spoke at (UIkonf). Their whole mobile team writes/reviews for both platforms.
