Traction scoreGitHub stars can be faked, so popularity alone can be misleading. Traction Score looks for broader signs of real attention, adoption, and active maintenance.
Description
This skill walks through a structured review process for SwiftData code: core rules, predicate safety, CloudKit constraints, indexing for iOS 18+, and class inheritance for iOS 26+. For each issue it reports the file, line, rule violated, and a before/after fix, then ends with a prioritized summary. It helps SwiftData developers and Apple platform engineers catch patterns that crash at runtime—like isEmpty in predicates or @Query outside SwiftUI views—before merging.
