What would you advise for iOS developers who would like to take their Swift programming further?

John Sundell: Imagine you have this virtual toolbox, and this toolbox contains many different tools. For me, I always want to just keep collecting tools into that toolbox. Whether that is coming from Swift, or whether it's coming from something Apple promotes, whether it comes from another community, whether it comes from another language, whether it comes from 20, 30, 40 years ago, it's all about trying to collect as much of those tools as you can.

“Imagine you have this virtual toolbox, and this toolbox contains many different tools. For me, I always want to just keep collecting tools into that toolbox.”

And then when you have them, I think it also makes you think more about when to apply which tool, because sometimes you see people who have clearly focused a lot on a specific framework or a specific methodology, or a specific tool, and they kind of use it as a silver bullet. They're like, “I love this technology, or this framework, or this particular way of doing things, so whichever problem I am encountering, I'm always going to tackle it this way.”

It's that classic thing: "if all you have is a hammer, everything looks like a nail." And I think as humans, that's kind of how we're built, right? We're built to recognize patterns, and then, if we find a solution, we're sticking to that solution because we know it works. But I think one way to combat that way of thinking, and something I do personally all the time, is just to keep trying to be open-minded and look for new things, because that way I don't fall into that trap of just thinking along the same lines over and over and over again.
