![]() Xcode will show you a list of templates for our new project. Instead, you should loop through your indexes, create an item for each row and populate it with the appropriate object. ![]() Instead, you reference the index as indexOfObject although the table does not have any objects yet. Open Xcode and select “Create a new Xcode project”. This method is the actual place where you add rows to your table. After adding a table object to your storyboard, configure the row controller that comes with the table. At that point, you can use the object in your outlet to make changes to the table. All the tutorials listed below are absolutely free. During the initialization of your interface controller, WatchKit creates a new instance of this class and assigns it to your outlet. Here you can find a collection of free tutorials that are target for beginners without possessing any coding experience, and developers with some iOS programming experience. Let’s start by creating an new Xcode project. At Appcoda, our aim is to teach everyone how to code and build an iOS app. ![]() Creating the Project and Adding the Target Each item can be selected to reveal more information about the country such as its capital. We’re going to make a simple table of 5 countries. In this tutorial, you’ll learn how to make a selectable table app for Apple Watch. In Practical and efficient WatchKit tables with view model diffing, I presented a way of making Apple Watch apps that simplifies application code and results in superior performance by moving UI updating logic to the framework layer and making it smart about pushing updates over the radio. A page-based interface consists of two or more WatchKit scenes through which the user is able to navigate by making left and right swiping motions on the Apple Watch screen. But today, let’s start with something basic. The WatchKit framework provides the infrastructure to create what Apple refers to as page-based interfaces within WatchKit Apps. Name the new class ScheduleInterfaceController. In the dialog that appears, select watchOS\Source\WatchKit Class, and click Next. Right-click on the Watch Extension group in the Project navigator, and choose New File. We will look into the new features of WatchOS 2 in future tutorials. The first thing you need to do is create a subclass of WKInterfaceController to control the table. The developer preview is already available and the public release will be available this fall. On top of that, we will also be able to develop apps for the Apple Watch itself! This means we will no longer need an iPhone to run the code. These include programmatic access to the digital crown, new ways to play video and audio, use of the built-in microphone and the Taptic engine. WatchOS 2 features a lot of new frameworks that are now accessible for developers. We’ll display it as a table, each row with a name and a checkbox to indicate if the item was purchased.Apple announced WatchOS 2 at WWDC this year. To illustrate the concepts in this article, we’ll make a very simple app - a shopping list. Every time your data changes, you will simply tell the framework what you want to display, and the framework will intelligently compute the smallest required set of interface changes for you. Together with a small set of additions to the WatchKit framework, this will free you from worrying about updating your UI in an efficient manner. We will introduce a thin layer between your interface controller and the views (tables, rows, labels, images…). In this post, I will show you how to dramatically simplify the architecture of your WatchKit application and improve its performance. You’ll find me on Twitter, building Nozbe, and making engineering blueprints. It reflects my views and the state of the world in 2015, but is likely to be outdated.
