Apple Swift Programming Language - Hello World

Swift is a new programming language for iOS and OS X apps that builds on the best of C and Objective-C, without the constraints of C compatibility.

In my efforts to learn the new language, I’ve decided I will be posting regularly as I step through the learning process, sharing everything I find. This is the first post of many on the topic, and I hope you decide to follow along!

Let's start with basic Xcode template..

1.  Create an Empty Application:

2. Now create a new UIViewController which will act as a rootViewController

3. So for instance in Objective-C where you have this:

 RootViewController *vc = [[RootViewController alloc] init];  

You now have this:

 var vc = RootViewController()  

4. You may have to get rid off from designated initializer from RootViewController class or you have to create instance with:

 var vc = RootViewController(nibName: nil, bundle: nil)  

5. Now create instance of UINavigationController and attach your vc instance to the rootViewController.

6. Build and run!

Move repo from bitbucket to github

Simple and pretty neat trick:

Lets say your project repository in my $HOME/dev/SampleProject directory.

cd $HOME/dev/SampleProject
git remote rename origin bitbucket
git remote add origin https://github.com/sample/SampleProject.git
git push origin master

Once your push has been successful to Github then you can delete the old remote by using:

git remote rm bitbucket

It'll only remove your local reference not your origin repository.

Tags:
You'll notice that your tags are still not visible in github. You may need to run single command on terminal:

git push origin --tags -f
