Note: I've kept the code for the views as simple as possible to focus on previewer experience. Try changing something on the nested view and see it being propagated to the simulator!

In the following example I've created a custom view to represent the control panel on the bottom of the screen (file Views/ControlPanel.xml): Hot Reload is smart enough to identify custom views and keep them updated as you edit, which allows for example to change the layout of a Collection View cell on it's own cell file and having it updated on the running app. You can keep doing this until you're satisfied, then you get to your next design subject. So, when you save the file, you should see that after a flash the whole content of the screen will be replaced in the running app. Please be mercyful with my design skills. It's not meant to be perfect, just to give us an entire new interface. This is a roughly and incomplete re-creation of the Interval Timer app main screen. Let's try to change the entire page layout, replace the inner of the ContentPage element with the following: You can keep doing changes to this file, and when you're happy with them just save it to have it deployed instantly to the running app. Save the file and see the 'magic':Īfter saving the file the page was refreshed with the changes you've made. Open the file on the editor while you keep the debugger running and let's change the header to a red background. This is the design of the MainPage.xml from the Blank project template. After creation just run the app on the simulator. Let's give it a try! Open Visual Studio and create a new Blank Xamarin.Forms project. If you've updated to the latest versions of Visual Studio and are working on new projects, Hot Reload is mostly 'there'.

Hot Reload allows us to avoid the expensive roundtrip of building and deploying the app to test UI tweaks, lettings us preview it directly on a device (which is the best method for testing our UI work).Īs changes made to XAML files are instantly updated in the running app, in practice Hot Reload makes the simulator a kind of real-time previewer. The XAML Hot Reload feature takes changes to a XAML file and instantly updates it in our running app. Let's take a look at them! XAML Hot Reload XAML Previewer: is a tool built to Visual Studio XAML editor, that allows us to have instant insight on the UI that you're working.XAML Hot Reload: allows us to make changes to change XAML code and have it updated on a running instance of your app, either on a simulator or a real device.Lucky as Xamarin.Forms developers, we have some great tools to facilitate this jobs:

Commonly you do several roundtrips between edits to test every dynamic and interactive aspect of the interface.

Writing a complex UI is for the most part a trial and error exercise. As developers we think of UI elements as dynamic components and interactive components. Drawing UI from an application framework is not like composing it on a tool like Photoshop by drawing and styling primitives (although its possible through shapes). Its hard to write UI code without seeing its actual output.

This allows developers to have full control over the rendering of the interface and split it into reusable components, but comes with drawbacks.

The most established front-end development workflows are based on transcribing designs based on static images to the components that actually render that screen at runtime.įor the Xamarin.Forms developers, UI's are written entirely in code, either through XAML or C#. Modern apps tends to use complex designs and need to adapt to the growing number of device sizes and form-factors. Building UI's has always been a hard job.
