Today I saw my friend using Cloud9, it's Cloud IDE, it has a small area called 'Commands' where he can search and read tiny description about it, also keyboard.

This cheatsheet includes:

Variables, including primitives and common variable types
Functions, including function declaration and usage
Operators, from logical operators to ranges to math – it’s in here
Classes, including class declaration, protocols, outlets, properties, initializers, extensions, lazy properties and class methods
Instances, including initialization and using properties
Control Flow, including if-elseif-else statements and switch
Loops, including for, while and Swift range syntax
Conditionals, including expressions, boolean logic and operators
Strings, including working with strings, converting from String to Int, and string interpolation
Optionals, including optional binding, optional chaining and force unwrapping
Dictionaries, including initialization and accessing key-value pairs
Arrays, including accessing values, adding values and looping over values
Sets, including what makes them special compared to dictionaries and arrays
Closures, including complete closure syntax, capturing and escaping
Guard & Defer, including early return with guard and deferred execution with defer
Generics, including generic types and function generics
Tuples, because while I’m at it I might as well add tuple syntax too…
Enumerations, including raw values, associated values and using enums with switch
Error Handling, including throwing errors and catching them with do-try-catch

The Swift Cheatsheet Is Open Source

Good things happen when you work together! My Swift 5 cheatsheet is open source. This means you can do with it whatever you want, as long as you keep the open source license intact.

The most successful people I know share their work. As you’re learning how to code iOS apps, making this your practice is essential.
