How does this skill handle data filtering?

It leverages the @Query macro combined with #Predicate to allow for both static and dynamic filtering of data directly within SwiftUI views.

What iOS version is required for this skill?

This skill focuses on SwiftData, which requires iOS 17 or later, with iOS 26+ and Xcode 26+ recommended for the latest features.

Does it support native iCloud synchronization?

Yes, it provides specific guidance on enabling native iCloud sync using the .automatic cloudKitDatabase configuration and iCloud-compatible model requirements.

Are there specific requirements for models to sync with iCloud?

Yes, iCloud sync requires all relationships to be optional and properties to have default values; the skill provides a checklist for these critical rules.

Can I manage many-to-many relationships with this skill?

Absolutely. It includes patterns for defining many-to-many relationships using the @Relationship macro and inverse properties.
