Swift is Apple's new programming language that can be used to write apps for iOS, Mac, watchOS and tvOS. It is an open source language that works with C and Objective-C, and provides type safety and modern language features. Playgrounds allow testing code in an interactive environment, and Swift can also be used on IBM's Bluemix platform. The language supports common data types like integers, strings and booleans, as well as variables, constants, comparison operators, loops, functions and more. Structs and classes can be used to define custom types along with features like properties, methods and initializers. Arrays, sets and dictionaries are also supported along with enumerations, protocols, extensions and error handling

6. Data Types
● Integers: 0, 1, 2, 42, 31337, -10
● String: “Kermit”, “Gonzo”, “Ms. Piggy”
● Double: 1.5, 3.14159, 81.2, 578.238
● Boolean: true, false

7. Variables

8. Constants

9. Comparison & Booleans

10. For Loops

11. Scope
“age” is available for entire scope
“myString” is available just in “for” scope

12. Functions

13. Default Arguments

14. Optionals

15. Struct vs. Class
Struct: Class:

16. Struct

17. Struct: Methods

18. Struct: Property Mutability

19. Struct: Instance Mutability

20. Struct: Properties

21. Class
● Similar features with
structs
○ Properties
○ Methods
● Need to write initializers
yourself

22. Arrays

23. Sets

24. Dictionaries

25. Enumerations
An enumeration defines a common type for a
group of related values and enables you to work
with those values in a type-safe way within your
code.
Features
● Method
● Computed Properties

26. Protocol

27. Stored Properties

28. Computed Properties

29. Property Access

30. Properties Sample
Computed Property
Stored Property

31. Extensions

32. Safe Unwrapping
Example

33. “ is ” keyword

34. Errors
Throwing Errors Handling Errors

35. Reference Counting

36. De-initializers
