Welcome to Code Completion, Episode 16! We are a group of iOS developers and educators hoping to share what we love most about development, Apple technology, and completing your code!
Follow us @CodeCompletion on Twitter to hear about our upcoming livestreams, videos, and other content.
Today, we discuss:
- More thoughts on the iPhone 12 mini, Mac mini, and HomePod mini
- Big Sur's release, and the launch issues that came about
- Fernando's new project, supplemental dev skills, and interview standardization
Also, join us for #CompleteTheCode and Compiler Error, two segments that test both your knowledge and our knowledge on Swift, Apple, and all things development!
Your hosts for this week:
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.

Complete the Code
- Unlike many languages, Smalltalk has no if statement, let alone other control structures. Control flow is instead implemented as methods sent to objects.
- Like Objective-C, Smalltalk makes use of argument labels on each of a methods arguments, but does not wrap every method call in square brackets.
- Only six "keywords" are reserved in Smalltalk: true, false, nil, self, super, and thisContext, which are called pseudo-variables in the language.
- Like many languages in the 80s, Smalltalk uses the dot character to access properties, the semicolon to delineate statements, and curly brackets to denote blocks.
