One of the best places to get your Swift fix on is John Sundells site. He's consistently posting new tutorials and diving into frameworks. Because of his consistency, his site is a wealth of Swift knowledge. He's launched a podcast and now he is introducing a monthly Swift newsletter. I have no doubt it's worth subscribing to. Make sure to check it out.

Cool. I've never used lazy sequences before. Consider me informed. 😀
These lazy variations work just like their regular counterparts, but with one twist: they have custom implementations of methods like map and filter in order to make them work lazily - meaning that the actual computations will only happen where and when you need them.
