Intro to iOS Development: Lecture 1 - Intro to Swift & XCode

Clarification on [22:00]: Only classes require an init, but you can also create an init function for structs, so that all properties aren’t required in its initializer. However, without overriding the init for a struct, all properties must be passed some value.

Demo:
8:29 - Playground, Let + Var, strings, printing
12:01 - Arrays
16:32 - Dictionaries
18:37 - Functions
20:02 - Structs + Classes
23:33 - Optionals
30:45 - Enums
