Using Swift Extensions The “Wrong” Way: When you should use extensions.
iOS Interview Problems via Swift 2.2: The Two-Sum: “So I figured I’d post the occasional problem here as solved via Swift. Starting with the ever popular “Two-Sum” problem. The Two-Sum problem has been asked of me several times throughout interviews. The problem is a variation of the “subset sum” problem. The subset sum problem requires dynamic programming (fun-fun) to solve, but the two-sum problem is much simpler and can be solved in O(n) time.”
Pattern Matching, Part 1: switch, enums & where clauses: “From a simple
switch to complex expressions, pattern matching in Swift can be quite powerful. Today we’re gonna start exploring it by seing some cool usages of
switch, before going further in later articles with even more advanced pattern matching techniques.”
Swift Enums Cookbook: “Swift Enums are super handy. With associated values, they can be used in some quite interesting ways. Today we’ll check out a couple. These aren’t working examples, but might spark some ideas. Let’s take a look.”
Afternoon Whoa: Swift’s guard case =: “What is your take on using the Swift 2 “guard case” syntax vs using the “~=” expression pattern?”
I ? Storyboards & Nibs: “One of my favorite talks at @tryswiftconf (ok, every talk was my favorite!) was when @helenvholmes talked about how to get designers into code. One of the big things to do is very obvious – use Storyboards! Immediately, this comment was a bit controversial among developers.”
Scene Kit Tutorial with Swift Part 1: Getting Started: “This tutorial series will show you how to create your first game with Scene Kit, Apple’s built-in 3D game framework.”

Building a Fitness App Using HealthKit to Track Walking Distance: “Today, we’ll be building a fun little app that both reads information from HealthKit and writes new data. Meet OneHourWalker.”
Think Like a Swift Developer: Whiteboarding: “Earlier this week, our collective was able to delegate a small project to myself and another developer. Once again, my mind raced through the gambit of emotion. Most of that emotion was excitement. Knowing that you are about to solve someone’s problem, with a iOS solution, is intoxicating.”
Supporting Peek & Pop on Older Devices with PeekPop: “Peek/Pop are great features, it’s a shame only our users with the latest hardware can take advantage of them. Today, we’ll check out a brand new library that aims to remedy this. It’s from Roy Marmelstein and called PeekPop. Let’s dive in.”
