1.2 Prerequisites

In order to follow along in this course you really only need one tool, Xcode. More specifically you will need at least Xcode 7: a free download from Apple’s App Store. In this lesson I’ll show you how to install it.

1.2 Prerequisites

As usual, before we start diving in to any sort of topics that are specific to Swift or Swift 2.0 or anything on the Apple platform. Like usual, we need to make sure we have all of the pre-requisites. And lucky for us, typically, that only means we need an IDE and then IDE as Xcode. Now, in order to use Swift 2.0 and a lot of the new features to target a lot of the new platforms and STKs, you're gonna need the latest version of Xcode. And the latest version of Xcode is Xcode 7, which was actually fully released at the time of this recording about a couple days ago on September 16th. So if you have a previous version of Xcode 7, one of the beta releases or maybe the GM seed, then you're gonna probably wanna get rid of that and start from scratch and install the actual full release version. Just so that we've at least gotten rid of all of these kind of bugs and things that have come up previously. Now that's not to say that we're not gonna run into any issues, or you're not gonna run into any issues when you're using the new version of Xcode in Swift 2.0. Because as usual, as I've mentioned in previous Swift courses, Swift is still evolving. It's a very young language, and we're still seeing a lot of modifications and updates and changes as we go along. Some of them are very simple things and are non-breaking, but some of them are breaking changes. And that's just the way that it goes when you start to adopt a new language, at least in its early stages like this. So don't be really afraid of that, it's gonna happen, so just kind of be prepared for that. But we are going to need Xcode 7. So if you do have it, then you should be ready to go. If you don't, once again, the nice thing about this is that it's a free download and that you can head over to the App store and simply search for Xcode. And you will be taken to this page where you can either click on the get button if you don't have it yet, or the update button if you maybe have a previous version of say Xcode 6. Then you can just go ahead and do an update. But once you've actually gone through that process, then you are ready to start doing Swift 2.0 development. So all we really have to do is open up Xcode and you're going to see here, that we have version 7.0 ready to go. And from this point you are ready to start building your applications. So in the next lesson, we're gonna cover a couple of the basic ways that we are going to be able to use Swift and how we're going to be able to use it when it comes to Xcode. So there's about three main options that you have that you can pretty much use to follow along in this course. But I'm going to suggest that we use one in particular just because it's easier and it provides the most rich set of functionality and tools. And probably the most reliable at this point. So let's go ahead and see what those options are.
