One of the things that makes writing Swift so fluid is that the Swift type inference system is strong enough for us to write type-safe code from a natural perspective, without having to pepper String and Int everywhere. Even with somewhat complex typing, such as generics, the compiler will know what to do. However, once… Continue reading →

Swift Evolution Proposal SE-0094 has been implemented in Swift 3, giving us an easy way to create lazy lists based on a starting value and a generator. One particularly cool thing about lazy lists is that you can have an "infinite list" — one that will keep giving you elements for any index. These are… Continue reading →

I recently posted a guide to writing FizzBuzz in Ruby without using any conditionals. I focused on functional/declarative programming themes because I felt they were a good model of how I approached the problem, and also because they made certain things easy, like iteration, which would otherwise pose a problem without conditionals. I had a… Continue reading →

A while ago, one of my coworkers suggested a fun exercise on a Friday afternoon: Solve the (in)famous FizzBuzz interview question…without using any conditional statements. It's a good "thinking outside the box" spin on the exercise, a little brain teaser for devs of all skill levels. There are several ways to do it, but today… Continue reading →

I recently configured an Android EditText to mimic Simplenote's iOS note UI – the first line of text is bold, and anything after that is normal. I had a simple static method to split a string at the first line break: public static String[] splitAtFirstLineBreak(String string) { return string.split("\n", 2); } and I implemented the… Continue reading →

After talking with several people and seeing other implementations of the "Swift Rewrite Challenge", I decided to revise my code using a more complete approach. In my first rewrite, I tried to stay true to the original function. This time, I broke the process down into different functions and extensions, and added functionality that I… Continue reading →

A few days ago, Erica Sadun posted a Swift function snippet and then rewrote it in her own style, discussing the changes. I decided to give it a shot, and (without looking at her version!) refactored the original function to suit my taste.
