This week, James is joined once again by friend of the show Dan Siegel, Microsoft MVP, who shows off his latest creation, Prism Template Studio & Developer Toolkit for Visual Studio for Mac.

[Visual Studio for Mac] Programming for watchOS with Xamarin and Visual Studio for Mac By April 2018 Small wearable devices like personal activity trackers and smart watches (such as Microsoft Band, Android Wear or Apple Watch) are becoming more and more popular. These wearables are equipped with various sensors, which monitor wearer’s health parameters in real time. Many wearables also have communication interfaces, so sensor data can be easily transmitted to custom or dedicated cloud services (such as Microsoft Health) for storage or advanced processing. As a result, the wearable can act as an additional endpoint in an Internet of Things (IoT) ecosystem. This, in turn, can help advance personal health care to a new level, where IoT predictive algorithms can inform the user about emerging health issues in advance. Wearables can also run custom apps.

Developers are provided with dedicated SDKs. However, as is the case for many mobile devices, each platform has its own specific API, which can be accessed through platform-specific programming languages and tools. To make things easier, Xamarin provides support for Android Wear and watchOS within the Xamarin.Android and Xamarin.iOS libraries, respectively. You can develop wearable apps in a similar manner as mobile apps, by utilizing the common.NET code base, which is referenced in the platform-specific projects.

In this article, I’ll show you how to utilize such an approach to build the watchOS app depicted in Figure 1. When you run this app, it begins retrieving the collection of objects from the REST Web service. This collection is composed of fake photos, each of which has a title and a bitmap (single color image). At this stage, the app only shows one button with the caption Get list. This button is disabled until the data is downloaded, as shown in the first row of Figure 1. Figure 1 A Preview of the watchOS App Tap the button and an action sheet (second row of Figure 1) appears displaying an alert that’s composed of several buttons, defined as actions or action buttons (). In this example, the action sheet provides the action buttons, whose captions contain the range of photos to be displayed.

When you tap an action, the selected photos are displayed in the table control () just below the Get list button as shown in the last row in Figure 1. This table is scrollable, so you can scroll down the list to see all photos in the group. I’ll implement the communication with the Web service in a separate.NET Standard Class Library (). Following the referenced documentation,.NET Standard is a formal specification of the.NET APIs designed to accomplish uniform access to programming interfaces available on all.NET implementations. One of the main advantages of this approach is that a shared library can be easily referenced in.NET projects to reduce or eliminate conditional compilation of the shared code.

As a result, the.NET Standard Class Library can be implemented once and then referenced in various.NET projects, targeting Universal Windows Platform (UWP),.NET Core, ASP.NET Core, Xamarin.iOS, Xamarin.Android, Xamarin.Forms and so on without the need to recompile for each platform. Setting up signature in outlook for mac. Parent App and Shared Code The structure of a typical watchOS solution comprises three projects (see and ). The first is the parent iOS app. Two other projects are dedicated to the watch app: Watch app bundle and WatchKit extension bundle. The parent iOS app is used as a proxy to deliver watch bundles to the wearable. The Watch app bundle contains interface storyboards.

As is the case with iOS, developers use interface storyboards to define scenes and segues (transitions) between them. Finally, the WatchKit extension bundle contains resources and the app code. Let’s start by creating the parent iOS app using the new Single View iOS project, which can be found in the New Project creator of Visual Studio for Mac. I set the project and solution names to Photos.iOS and Photos, respectively. After creating the project, I supplement the Photos solution by adding another project Photos.Common, which I create using the.NET Standard Library project template. This template is located under the Multiplatform Library group of the New Project creator. When you create the.NET Standard Library you’re given an option to choose the version of.NET Standard.
