View Pattern for Swift Errors.swift
// Swift's untyped errors are a goddam PiTA. Here's the pattern I use to try to work around this.
// The goal is basically to try to guarantee that every throwing function in the app throws an
// ApplicationError instead of some unknown error type. We can't actually enforce this statically
// But by following this convention we can simplify error handling
enum ApplicationError: Error, CustomStringConvertible {
// These are application-specific errors that may need special treatment
case specificError1
case specificError2(SomeType)

Init based Storyboard View Controller Instantiation
View SampleViewController.swift
final class SampleViewController: StoryboardBackedViewController {

private var member: Foo!
// Proper dependency injection in a storyboard backed VC!
init(foo: Foo) {
super.init(storyboardIdentifier: "SampleViewControllerIdentifier")
// We have to set the members *after* calling super.init, since it changes the instance of `self`.
self.member = foo

Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

Data Structure Basics

###Array ####Definition:

  • Stores data elements based on an sequential, most commonly 0 based, index.
  • Based on tuples from set theory.
View libyaml.swift
// gem install cocoapods-playgrounds
// pod playgrounds LibYAML
// Update: @floriankugler had a great idea to use UnsafeBufferPointer
// Paste in the following:
import LibYAML
public struct YAMLError: ErrorType {
