Overview of this book

This book is intended for .NET developers with any level of experience and who are interested in building native applications without the hassle of becoming Objective-C or Java experts. Although it will be beneficial to have some development experience, particularly in .NET, Learning Xamarin help even a novice developer get past the headaches of setting up and customizing their new development environment so they can move on to producing high-quality native applications quickly.

Now that you are familiar with the fundamentals of simulator testing, let's discuss testing our apps on physical devices. We have already covered how to set up your physical devices for testing in Chapter 1, Installing and Setting Up Xamarin Studio, so all that's left is to debug an application on a device from each platform. As discussed earlier in the Simulators section of this chapter, you should test all of your functionality on a physical device. That's because the most effective way to certify the behavior and stability of your application is by using it in a real-world environment. If it functions as expected, without crashing, hanging, returning bad values, and so on, then the app is probably ready for release.

Testing on an iOS device

Let's begin with testing on an iOS device.

Note

If you do not intend to develop iOS applications, or if you do not currently possess a physical iOS device to test on, you may skip this walkthrough for now and come back to it whenever you...
