Is it possible to create an app with only swift ? : <p>I've started to learn swift and it is told to be a very fast language who takes over the Objective-C. But at many times, I saw it is not enough to write only with Swift and it was need others languages. So I would know if with my MacBook, Xcode and Swift only, it's possible to create app like Snapchat, Instagram WhatsApp or other.</p>

<p>Thanks you.</p>
