Visual Studio Version 15.8.5 fixes this. The release notes contain the following text: Visual Studio Tools for Xamarin now supports Xcode 10, which allows you to build and debug apps for iOS 12, tvOS 12, and watchOS 5.

When creating iOS apps, developers typically turn to the languages and IDE provided by Apple: Objective-C / Swift and Xcode. However, this isn’t the only option—you can create iOS apps using a variety of languages and frameworks. One of the most popular options is, a cross-platform framework that allows you to develop iOS, Android, OS X and Windows apps using C# and Visual Studio.

The major benefit here is Xamarin can allow you to share code between your iOS and Android app. Xamarin has a big advantage over other cross-platform frameworks: with Xamarin, your project compiles to native code, and can use native APIs under the hood. This means a well written Xamarin app should be indistinguishable from an app made with Xcode. For more details, check out this great article. Xamarin had a big disadvantage too in the past too: its price.

Because of the steep licensing cost of $1,000 per platform per year, you’d have to give up your daily latte or frappuccino to even think about affording it and programming without coffee can get dangerous. Because of this steep price, until recently Xamarin appealed mostly to enterprise projects with big budgets.

However, this recently changed when Microsoft purchased Xamarin and announced that it would be included in all new versions of Visual Studio, including the free that’s available to individual developers and small organizations. Now that’s a price to celebrate! More money for coffee! Besides cost (or lack thereof), Xamarin’s other virtues include allowing programmers to: • Leverage existing C# libraries and tools to create mobile apps. • Reuse code between apps on different platforms.

• Share code between ASP.Net backends and customer-facing apps. Xamarin also offers a choice of tools, depending on your needs.

To maximize cross-platform code reuse, use. This works especially well for apps that don’t need platform-specific functionality or a particularly custom interface. If your app does require platform-specific features or designs, use, and other platform-specific modules to get direct interaction with native APIs and frameworks. These modules provide the flexibility to create very custom user interfaces, yet still allow sharing of common code across platforms. In this tutorial, you’ll use Xamarin.iOS to create an iPhone app that displays a user’s photo library.

This tutorial doesn’t require any prior iOS or Xamarin development experience, but to get the most from it you’ll need a basic understanding of C#. Getting Started To develop an iOS app with Xamarin and Visual Studio, you’ll ideally need two machines: • A Windows machine to run Visual Studio and write your project’s code. • A Mac machine with Xcode installed to act as a build host. This doesn’t have to be a dedicated computer for building, but it must be network accessible during development and testing from your Windows computer. It greatly helps if your machines are physically near each other, since when you build and run on Windows, the iOS Simulator will load on your Mac. I can hear some of you saying, “What if I don’t have both machines?!” • For Mac-only users, Xamarin does provide an IDE for OS X, but in this tutorial we will be focusing on the shiny new Visual Studio support.

So if you’d like to follow along, you can run Windows as a virtual machine on your Mac. Tools such as or the free, open-source make this an effective way to use a single computer. If using Windows as a virtual machine, you’ll need to ensure that Windows has network access to your Mac. In general, if you can ping your Mac’s IP address from inside Windows, you should be good to go. • For Windows-only users, go buy a Mac right now. I’ll wait!:] If that’s not an option, hosted services such as or provide remote Mac access for building. This tutorial assumes you’re using separate Mac and Windows computers, but don’t worry—the instructions are basically the same if you’re using Windows inside a virtual machine on your Mac.

Installing Xcode and Xamarin If you don’t have it already, on your Mac. This is just like installing any other app from the App Store, but since it’s several gigabytes of data, it may take a while. Note: You won’t see this instance variable within ViewController.cs itself. To see the the instance variable, click the disclosure indicator to the left of ViewController.cs to reveal ViewController.designer.cs inside. This contains the collectionView instance variable automatically generated by Visual Studio. Open ViewController.cs from the Solution Explorer and add the following field right inside the class: private PhotoCollectionDataSource photoDataSource; At the end of ViewDidLoad(), add these lines to instantiate the data source and connect it to the collection view. PhotoDataSource = new PhotoCollectionDataSource(); collectionView.DataSource = photoDataSource; This way the photoDataSource will provide the data for the collection view.
