Interactive @Query in SwiftData - Change Query Properties with a Picker (ToDo List App)
How do you get a SwiftData Query to change its attributes / parameters interactively? In this lesson we'll show how you can use a Picker view in SwiftUI to send selections to a View, and have that View respond to the interaction by selectively initializing a Query with different .sort, ..order, and .filter / #Predicate parameters. We'll also learn to use _variableName to initialize a Swift Property Wrapper.
