[MUSIC] Hello. As we're getting to the end part of course one and we're beginning course two and the remaining part of this specialization. I wanted to provide some commentary about where we are, what direction we're going to go and some changes we're going to make along the way. Now, our goal with course one w as always an informal way to understand Swift, get to know X code, and be able to have fun in playgrounds. And it's informal mechanism was mainly meant to introduce everyone to the environment and the language that we'll be using. But this was just set up. The main objective that we have for this specialization as a whole is to build a mobile app and build an iPhone. So, now that we know Swift, we've essentially played a bit with Swift, although I don't think anyone is necessarily an expert at this point. And now that we know how to use X code. Now is really the important part, the specialization, which is starting in course two. How do you build your own iPhone app? And we're going to begin with something very simple, something you just has a single button that you can import an image, maybe do a simple process on it. And over every module in course two, things will become more and more advanced. We'll start by looking at how do you create different UI layout. How do you manage different things and place them in different places? How do you, for example, create a different view or different UI element and link it to your code? So all things that you need to build your own application. And this course two is now where we get very serious to the point and we start combining some of the basic things we learned into an actual iPhone app which is now starting in course two. Now I do wanna comment, there have been a few issues with recordings being made before. Comments about the audio quality, the video quality and some of the jokes we've made perhaps. But those should now be all addressed. Now, most people hopefully will be happy with the quality they see. There still will be some feedback and some comments I'm sure will be coming our way, which we always welcome that. But we hope you like the new quality of videos and audio and every other detail about this second course. And as always we really welcome your feedback, your enthusiasm. If you have anything you wanna tell us or any advice, suggestions, please feel free to do so. So let's get started with course two.
