Update 8/4/17: Updated for Swift 4 and Xcode 9.
Sometimes when learning a new language it’s handy to have a cheat sheet as you are getting used to syntax.
So I’ve made this cheat sheet for learning Swift 4:
It summarizes the most important Swift syntax on one page to get you up to speed quickly, including:
- Class Implementation
- Creating/Using an Object
- Declaring Variables
- Control Flow
- String Quick Examples
- Array Quick Examples
- Dictionary Quick Examples
You can also download a Swift 4 playground with the examples from the cheat sheet.
Let me know if you have any comments/suggestions on how to improve this. I’ll be updating this periodically as Swift changes.
