I will update your iOS app (iPhone or iPad) to iOS 10 working with Swift 3. The app must be written in the previous version of Swift, otherwise the code upgrade will required more time to be done. This include the dependencies updates, they should be up to date as well. To avoid misunderstanding, not all of the dependencies support Swift 3 yet and finding a proper one to fit in will add additional cost.
