Welcome to Code Completion, Episode 4! We are a group of iOS developers and educators hoping to share what we love most about development, Apple technology, and completing your code on this brand new show! This time, we are joined by special guest, Dan Morse! Be sure to follow them on Twitter at @danandami.

Follow us @CodeCompletion on Twitter to hear about our upcoming livestreams, videos, and other content.

Be sure to also sign up to our monthly newsletter, where we will recap the topics we discussed, reveal the answers to #CompleteTheCode, and share even more things we learned in between episodes.

You are what makes this show possible, so please be sure to share this with your friends and family who are also interested in any part of the app development process.

⭐️ This Week's Topics

• What interviews are like in 2020 when everything is remote.
• How to get acclimated to a new team as a junior developer.
• The pros and cons of Test Driven Development.

🚧 #CompleteTheCode

This week's #CompleteTheCode:

Invert and reduce the following if statement without introducing any new variables or statements:

1
2
3
4
5
6
7
8
9
10
11
12
let boolA, boolB, boolC: Bool
let intA, intB, intC: Int

// TODO: Invert this statement so we don't need an else block:
if boolA && !boolB || (boolC && intA == intB || intC > intA) {
    // Do Nothing
} else {
    print("The condition above was not met. Do the thing!")
}

// !(boolA && !boolB || (boolC && intA == intB || intC > intA))
// ... is not a solution!

Be sure to tweet us with hashtag #CompleteTheCode if you know the answer!
