Automating Provisioning Profile Refreshes in Xcode

Refreshing provisioning profiles is a pain. Okay, everything about provisioning profiles is a pain. This pain is amplified once you add a continuous integration environment into the mix. When you add to that a white-label platform like ours with a ton of apps building in it, things get very frustrating. For every app we add to the system, not only do we need to provision everything properly in the developer portal, but we also need to…

Solving a Stuck Automated UI Test on iOS

We've been using Xamarin's UITest framework quite a bit, both for standard test automation as well as some other tasks (more on that to come). Things had been working great, but after some recent upgrades to the latest versions of Xcode and the iOS tools, we were seeing our automated tests get stuck in one specific spot in the app's flow. Nothing particularly interesting was happening in this spot: it was making a network call out…

Extending Xamarin Studio's mdtool For Fun and Profit

Polyglot Apps for iOS, Android and Beyond

It's well known by now that you can use C# to write apps for iOS and Android by leveraging Xamarin tools, especially if you've been following this column. It's also well documented that you can take a lot of that C# over to other platforms such as Windows Phone and Windows Store, but did you know you can use F#, Visual Basic, Razor, HTML, and JavaScript in your apps, as well?

Auto-Formatting Text Inputs with MvvmCross and Value Converters

Value converters are one of the powerful features you get with an MVVM framework, and can be a lot of fun to experiment with. In my app I have many different types of text entry, and wanted to have an easy way to do automatic formatting for things like phone numbers and credit card numbers. Value converters to the rescue! Achieving this behavior using value converters was actually quite trivial. Here’s an example of a…
