 &gt; Over the years, the original version of Lyft had ballooned to 75,000 lines of code. By the time the company was done recreating it in Swift, they had something that performed the same tasks in less than a third of that.<p>I recently read a tutorial on how to make an Uber app on Swift that was fairly short (although not complete yet) [0]. 75k lines of code seems like a lot, even if it&#x27;s down to a third of that. From personal experience, I know that code grows very fast when you start adding features but I can&#x27;t point to any one reason why it should have to.<p>[0] <a href="http:&#x2F;&#x2F;shrikar.com&#x2F;build-your-own-uber-app-in-swift&#x2F;" rel="nofollow">http:&#x2F;&#x2F;shrikar.com&#x2F;build-your-own-uber-app-in-swift&#x2F;</a>
