body: <p>Recently I developed an app and I want to submit it to the App store, but I developed this app on <strong>Xcode 10.1</strong> in which maximum support Swift version is <strong>4.2</strong> and deployment target in 12.1 
         now question I want to ask as Apple released <strong>Xcode 10.2</strong> with <strong>Swift 5</strong>. so can I upload this app to app store or it is necessary to develop this app in <strong>Xcode 10.2</strong>?</p>
