Ever since the introduction of iOS, there is iOS development fever across the globe. Many iOS developers & companies are making fortunate out of it. By using Objective-C and Apple homebrew XCode SDK, there are more than 1 million apps in Appstore now! Apple didn't stop there, they are going to push it to another level by introducing a new high level programming language - Swift. Objective-C without the baggage of C is how Craig Federighi described it during the conference.

Swift is designed to be fast, modern, safe and interactive. Even though it is a high level programming language, its speed is much more faster than Objective-C. You can mix it with Objective-C and C altogether in a project too (Not a good idea though!).

Honestly, I was pretty excited about Swift. I wanted to dive into iOS development, but as a web developer for half of my life, it isn't easy for me to get into programming with low-level language. So, this announcement is actually quite an exciting news to me. I started to find resources about it and even started to learn how to use XCode. I decided to start from basic of Objective-C so I'll know the differences. It was a painful process. Objective-C has been serving Apple well for 20+ years, and I must say, it is not a friendly language at all.

As a PHP developer, I found Objective-C is a beast, very steep learning curve and a lot of weird and repetitive coding. To cut it short, it's indeed a low-level language, too low to my liking. My motive to learn the basic of Objective-C is to know the native solution first before moving on to high level. Just like how we start by learning Javascript first before moving on to jQuery.

Swift does a lot behind the scene to eliminate all those inconveniences and tedious practives of Objective-C. As a result of that, Objective-C codes are being simplified into shorter code and easier to understand. Take the following code illustrated during the conference as example:

Objective-C

if (myDelegate != nil) {
	if ([myDelegate respondsToSelector: @selector(scrollViewDidScroll:)]) {
		[myDelegate scrollViewDidScroll:myScrollView];
	}
}

Swift

myDelegate?.scrollViewDidScroll?(myScrollView)

Variable assignment is almost the same with Javascript except they eliminate the needs of semicolon. Comparing to Objective-C, it's just painful to write. Here is the declaration of String type variable.

Objective-C

NSString *myString = @"This is my string.";	

Swift

var myString = "This is my string."	

Are you getting excited yet? During the my own research and learning, I found a good collection of useful resources about Swift. If you started to learn it just like I do, this list will be very handy. But first of all, you need the SDK. Swift is only available in XCode 6 Beta which only available for those with Apple Developer account, but if you search around *ahem*, you will able to download it elsewhere.

Here you go, below is a list of resources, you will get written tutorials, video tutorials, references, sample codes and swift community. Drop me a commnet if you discovered something useful. Enjoy!

Introduction

Tutorial Series #1

A simple and short tutorial created by Fábio Rocha.

Tutorial Series #2

A comprehensive Swift tutorial created by James Quave. This 6 parts tutorials focus on created iOS app. You will learn from basic to advanced techniques such as web API request, Parsing JSON, Table View, Async image loading & caching, interaction with multiple views and best practices.

Tutorial Series #3

This tutorial will walk you through the creation of a geolocation based alarm app for travelers. The concept is simple: users create a new alarm by selecting both a geographic region and music item from their library. When the phone detects itself crossing the region boundary of an alarm (enter or exit) the relevant music plays.

Tutorial Series #4

We Heart Swift is a new website dedicated for Swift programming. They are going to be covering cool stuff they found.

Video tutorials

Sample Code

Sometimes, the quickest way to pick up a language is to learn by sample. Here we have a list of Swift Applications that you can download and study it.
