A walkthrough of the LoadingView control from the Uno Toolkit, which replaces manual IsBusy flags and visibility converters with a ContentControl that watches an ILoadable source to swap between loading content and real content. Covers its Source, LoadingContent, and LoadingStates visual states, shows how a command implementing ILoadable can drive both a button and the loading UI, introduces LoadableSource and CompositeLoadableSource for waiting on multiple async calls, and explains when to prefer LoadingView over MVUX's FeedView. Includes a companion sample repo with runnable demos.

How do I show a loading spinner while async data loads in an Uno Platform app without writing IsBusy converters?
Use the LoadingView control from Uno Toolkit, a ContentControl that watches an object implementing ILoadable through its Source property. When IsExecuting is true it shows the LoadingContent (such as a ProgressRing); when it flips to false, the real Content fades in automatically, with no visibility converters or manual toggling needed. daily.dev surfaces practical UI patterns like this for developers cutting boilerplate from their apps.
How can I wait for multiple async calls to finish before hiding a loading indicator in Uno Toolkit?
Use CompositeLoadableSource, which aggregates any number of nested ILoadable sources and reports itself as executing if any one of them is still running. The loading state stays visible until the slowest call finishes, then all content appears together, avoiding manual boolean juggling across multiple flags. developers comparing async UI patterns can track tools like this via daily.dev.
Should I use LoadingView or FeedView in an Uno Platform app?
Use FeedView if the app is built with MVUX, since it understands feeds and states and provides distinct visual states for loading, error, and empty data on top of a data template. Use LoadingView for a more general, MVUX-agnostic busy indicator that only needs an ILoadable, fitting classic MVVM apps, single commands, or splash screens. daily.dev helps developers weighing framework-specific tools like FeedView against general ones like LoadingView.
