While the Apple iWatch hasn’t been released yet, they have released WatchKit, so developers can start creating applications. For this post, I created a video that will walk you through building a watch application that displays the text “Hello World” after a button is pressed. I would also recommend reading the first post in this Code Challenge series that goes over building your first Swift App.


  • xcode 6.2 Beta : You might already have xcode installed on your machine, but to build iWatch apps you require the new 6.2 beta. This will install a new version of xcode on your machine that comes with the capability of building iWatch apps. You can download it here: https://developer.apple.com/xcode/downloads/
  • Developer Account: Make sure you at least have a free Apple Developer account to download the latest version of xcode.

Building the App:

Like I said earlier, for this app, I created a YouTube video detailing the process of creating the app for the iWatch. You can watch the video below:

Over the next few weeks, I’m going to continue writing about different technologies, so check back every Monday, Wednesday, and Friday for new tech posts! You can also visit my intro post that will have an updated list of everything I’ve written.
