Introduction to Swift1:06
Introduction to course : Swift
Setup Xcode and Hello Swift4:47
How to setup Xcode 6 and first look of playground.
Discussion forum0:16

Constants and Variables3:19
Introduction to Swift constants and variables
Swift constants and variables
Type Annotations1:34
How a variable and constant type is declared.
Type Annotations
Naming convention4:39
Swift convention for naming variables and constants.
Naming Conventions
Printing, comments and semicolons5:12
This lecture will show how to print string, use comment and semicolons;
Printing, comments and semicolons
Integers4:34
Learn about integers in Swift, including signed and unsigned types, their zero and negative ranges, and how 8, 16, 32, and 64 bit sizes influence type behavior and inference.
Integers
Floating-Point Numbers1:39
Type Safety and Inference4:24
Swift has a strict type safety management system. There will be compile time error if type mis matches in variable or constant while assigning value.
Type Safety and Inference
Numeric Literals6:07
There are four types of numeric literals: decimal, binary, octal, hexadecimal.
Numeric Literals
Numeric Type conversion4:16
It is possible to convert any type of numeric literal to a different type of numeric literal in Swift.
Numeric Type Conversion
Type Aliases1:25
Type aliases introduce a new name for an existing type, enabling a max file size alias on a 64-bit platform and easy swapping of int with unsigned int.
Type: Boolean3:02
Swift has Boolean type bool for variable and constant.
Tuples4:47
Explore swift tuples, a non-homogeneous value group useful for returning from functions. Access by index, decompose into name and age, and destructure while skipping missing values.
Tuples
Optionals5:00
In Swift any variable or constant can be declared as optionals. It means it may have value or it may not. Let's see in the lecture.
Optionals
Optional Binding2:25
Assign a optional value and check for existence at the same time in optional binding.
Special Value: nil1:36
nil in Swift is bit different than in Objective-C
Implicitly unwrapped optionals2:50
It is just another way of declaring optional variable which can not be nil after declaration.
Implicitly Unwrapped Optional
Assertions3:26
Assertions check for condition and continue execution if it is true.

Terminology2:44
Assignment Operator3:04
Assignment operator (=) sets value to constant or variable.
Assignment Operator
Arithmetic Operators3:30
Normal arithmetic operators in Swift covers addition, subtraction, multiplication, division.
Arithmetic Operators
Remainder Operator3:36
Remainder operator (%) in Swift is almost similar to C. Let's see the difference.
Remainder Operator
Increment and Decrement Operators4:45
Increment (++), decrement (--) operator modifies single variable.
Increment and Decrement Operators
Compound Assignment Operators1:37
Compound assignment operator combines assignment with another operation.
Compound assignment operator
Comparison Operators3:04
Comparison operator compares variables and returns Boolean value: True or False
Comparison Operators
Ternary Conditional Operator2:28
Ternary operator has three parts and let's see in our lecture how it works.
Ternary Conditional Operator
Range Operators4:56
Range operator contains range value inclusive or half inclusively.
Range Operator
Logical Operators5:50
Explore how logical not reverses boolean values, how logical and requires both true, and how logical or yields true if any true; use parentheses to control evaluation order.
Logical Operators

Intro1:37
String contains encoding independent Unicode characters
String Literal2:40
Initializing empty string2:28
Declare an empty string in swift using string literals or a string initializer. Assign it to a variable and print whether it is empty or has a value using isEmpty.
Empty String
String Mutability and Value Types3:03
Mutability and value type
Characters2:14
Concatenation2:44
Concatenation of string
Interpolation2:18
Interpolation
Comparison3:40
Explore how to compare strings in Swift with three methods: equality, prefix equality, and suffix equality, including case sensitivity and practical examples.
String Comparison
Case conversion1:03
Discover how to convert strings to uppercase or lowercase in Swift using straightforward functions. Explore examples that show lowercased and uppercased results on a sample string.
Unicode3:41

Introduction to collection type1:02
There are two types of collection types in Swift: Array and Dictionary.
How to declare array collection type2:55
There are two ways to declare an array.
Array declaration
Accessing and modifying an Array12:25
This lecture contains how to access array value, modify value, append value and remove a value.
Accessing and modifying array
Iterating over array2:40
for-in or enumerate can be used to iterate over an array.
Iteration over an array
Creating and initialization of Array4:17
It's easy to declare and initialize an Array with default value in Swift.
Initialization of Array
Dictionaries2:46
Dictionary contains unordered list of key, value pairs.
Dictionary literal3:18
Dictionary can be declared with literal with a pair of key, value item.
Dictionary
Accessing, modifying and deleting dictionary8:38
Learn how to access, modify, and delete dictionary entries in swift by using count, add and update values for keys, and safely handle missing keys with optionals.
Accessing and modifying dictionary
Iterating a Dictionary3:19
Creating Empty Dictionary1:44
Mutability3:23
Explore mutability in Swift by comparing arrays and dictionaries under variable and constant assignments. Learn that constant arrays cannot change size, constant dictionaries cannot change values, while variables can mutate.
Mutability

Intro1:56
For-in loop8:49
Control flow - for loop
For-condition-increment loop2:28
Master the for condition increment loop by learning its initialization, condition, and increment parts, converting from for-in loops, and applying practical examples and exercises.
While loop4:41
Conditional if statement5:33
Conditional Switch statement13:53
Learn how to use Swift's switch statement to match values with multiple cases, ranges, and a default, without breaks, and apply it to grades, parity, and exhaustive patterns.
Switch control
Control Transfer Statement12:03
Control Transfer Statement
Labeled statement4:30

Requirements

OS X version 10.9.3 or later
XCODE 6 or later

Description

Apple has brought new programming language this june, 2014. Out of no where Apple declared Swift. It's innovative language for both Cocoa and Cocoa Touch. The fun part is interactive coding. It's a type safe language. Swift code can run besides Objective-C.

Swift cares lot of things automatically. If you already have a bit of experience from C, C++, PHP or Javascript, you already know a bit of Swift programming. This course will show those feature and pretty cool features of Swift.

As it is a new language, it is the right time to start right away. If you have developer license, you can download Xcode 6. By the time, I am making this tutorial, Apple has released Xcode 6 beta version. It will be possible to learn Swift without Xcode, cause these courses will show all code and output side by side. Courses come up with quizzes. So, you can practice always what you have learned. The more you practice, the more experience you will get. So why wait, let's dive in!!

This course will cover basics of Swift, operators, strings, collection types, control flow and functions. All of these has pretty cool features.

Finally, any kind of feedback is very much welcome. It is your input which will make this course more attractive. If you need any explanation, feel free to contact always.

Who this course is for:

Any one interested in programming language can take this course
Prior knowledge of C, C++, PHP or Javascript is good but not necessary
If you have passion for Apple, give Swift a try. It's awesome and be expert of it.
