.NET MAUI: iOS ListView disappearing cells

This content has 1 year. Some of the information in this post may be out of date or no longer work. Please, read this page keeping its age in your mind.In this article, we will delve into a persistent .NET MAUI issue affecting ListViews on the iOS platform in .NET 7 builds. While the .NET 8 preview has addressed this issue, developers seeking a solution can employ the BindableLayout as a temporary workaround. We’ll also explore the concept of BindableLayout and touch on the CachingStrategy within ListViews. The Problem: Disappearing Cells in ListViews on iOS The issue at hand revolves around the behavior of ListViews on the iOS platform in .NET 7 builds. As users scroll through the list elements, the ListView cells mysteriously disappear, causing a jarring experience. While the .NET 8 preview has resolved this vexing problem, the official release is still pending, leaving developers seeking immediate solutions. The Workaround: BindableLayout within ScrollView A viable workaround to mitigate the disappearing cell issue involves utilizing the BindableLayout within a ScrollView. The BindableLayout.ItemSource property can be harnessed to mimic the ListView’s behavior. However, it’s crucial to acknowledge that this solution might not deliver the same performance as a native ListView. Example Code Here’s how you can implement the BindableLayout workaround: BindableLayout: A Glimpse BindableLayout is a versatile feature within the .NET MAUI framework that allows developers to easily bind collections to layout controls. It’s an excellent alternative when dealing with scenarios where a native ListView isn’t performing optimally or in…

.NET MAUI iOS Bug – Release Mode Bindings Not Working

This content has 1 year. Some of the information in this post may be out of date or no longer work. Please, read this page keeping its age in your mind.Software bugs can sometimes manifest in specific environments or platforms, leading to unexpected behavior. In this blog post, we will discuss a bug in .NET MAUI specifically affecting iOS platforms. The bug causes bindings between Views and ViewModels to fail in Release mode, resulting in empty Views without the expected data. We’ll explore the symptoms of this bug and present a workaround that involves utilizing the XamlCompilation attribute with the Skip option. Symptoms The bug we are addressing affects the binding functionality in .NET MAUI apps running on iOS platforms in Release mode. When encountering this issue, Views fail to bind with their associated ViewModels, resulting in empty Views that appear as if no BindingContext is present. What is XamlCompilation? XamlCompilation is an attribute provided by Xamarin.Forms that allows developers to specify how XAML files should be compiled. It offers three options: None, XamlC, and Skip. Providing workaround To mitigate this bug, we can utilize the XamlCompilation attribute with the Skip option on the affected Views. This attribute is used to control the compilation behavior of XAML files in .NET MAUI applications. Identify the Affected View First, identify the View(s) in your .NET MAUI app that are experiencing the binding issue specifically on iOS platforms in Release mode. Add XamlCompilation Attribute Add the XamlCompilation attribute to the affected View’s code-behind…

Xamarin.iOS : “Failed to compile the generated registrar code” on Visual Studio for Mac

Please, read this page keeping its age in your mind.If you have recently upgraded your XCode version to 14.0, and installed the XCode command line tools too, you will probably notice some error messages when trying to run your Xamarin.Forms, or iOS application from Visual Studio for Mac. What actually helped me, is this:Navigate to https://developer.apple.com/download/all/ and search for Command Line Tools for Xcode 13.4 and Xcode 13.4. Both downloads are big, the XCode itself around 10GB and the CL Tools are around 1GB, so definitely do not do this on metered connections. Once the downloads are ready, open the XCode.XP file with the Package Archiver, let it extract to downloads, then move it to Applications folder. After that, install CL tools. Follow the installer’s instructions. Boom, it’s solved. Issue reported at: https://github.com/xamarin/xamarin-macios/issues/15954
