Dark mode, Marzipan and who knows what else await us which means we’re not far from Tim Cook and Friends revealing iOS 13 to the world. With a ton of services announcements already taken care of such as Apple TV+, Apple News+ and more - the tea leaves indicate that they’re going hard on pure API news this year.

At this point it’s all conjecture, so let’s ready up with the fifth annual Swiftjective-C WWDC Pregame Quiz!

If you’d like a quick primer on how this all works or how it got started, check out the first four quizzes from 2015 ,2016, 2017 and 2018.

Now - Lets.Play(with:🔥)!

Ground Rules

There are three rounds, and the point break down is as follows:

  • Round 1 – 1 point each answer
  • Round 2 - 2 points each answer
  • Round 3 - 3 points each answer

The last question of each round is an optional wildcard question. Get it right, and your team gets 4 points, but miss it and the team will be deducted 2 points.

Round 1 — Swift Decisions

Question 1:
What’s the name of the Swift attribute, added in Swift 5 to bolster dynamic language interoperability, that allows one to call named types like you’d call functions using a simple syntactic sugar?


@(the attribute name) struct SwiftjectiveC 
    func showArticles(withTags: [String]) {}

let instance = SwiftjectiveC()

instance("Foundation", "Swift")
// This will desugar down to instance.showArticles(withTags: ["Foundation", "Swift"])

Question 2:
In Swift, variables are initialized before they are used by a concept enforced by LLVM’s optimizer. What is this concept in computer science referred to as?

Question 3:
SIMD Vector and Result types were finally added to Swift in an official capacity in what version?

Question 4:
Before Apple’s Swift was announced, there already existed a parallel programming language by the same name - who were its developers?

Before Swift was a popular programming language at Apple, it was also the codename for an Apple-designed processor - which one was it?

Round 2 — iOS History 101

Question 1:
Auto Layout, long a core component of laying out user interfaces on macOS, didn’t arrive on iOS until which major release?

Question 2:
Security is a hallmark feature of iOS, and this specific feature involves placing data in random locations in memory and works alongside ARM’s XN (Execute Never) feature to prevent buffer overflow attacks - what is it?

Question 3:
When iOS was still shrouded in secrecy within Apple, how old was the youngest engineer working on iOS 1.0?

Question 4:
When the iPhone was first launched on June 29th, 2007 its operating system wasn’t yet referred to as iOS until iOS 4. What was its original name?

Leading the way to haggle all of your friends who appear as green bubbles in your conversations, in which version of iOS did iMessage debut?

Round 3 — Apple Myth and Lore

Question 1:
Leading up to its March 25th, 2019 “It’s Showtime” keynote, Apple live streamed Carplay displaying a six hour ride - where was its end destination?

Question 2:
Steve Jobs, long known as being a master of details, hotly debated what aspect of an Apple Store’s bathroom signs?

Question 3:
What was the very first thing ever rendered in a Safari browser, produced by Ken Kocienda during its development?

Question 4:
To ensure that a visiting Ross Perot wouldn’t think Apple and its employees were too rich for investment - Steve Jobs had himself and Randy Adams hide what objects before he arrived?

What original Apple employee quickly sold off their 10% share of the company in 1977 for only $800 (which would be worth billions today)?
