Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned dagba/ios-mcp at 526306aff8.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

The SwiftData Core Data Persistence skill enables AI agents to manage local data storage within iOS applications using Apple’s modern SwiftData framework, bridging legacy Core Data patterns with new syntax. It allows agents to define models, configure persistent stores, and execute fetch requests directly in the app environment.

When to use it

  • Migrating existing iOS projects from Core Data to SwiftData for improved developer experience.
  • Implementing local caching strategies for offline-first mobile applications.
  • Managing complex relationships between entities in a type-safe manner within SwiftUI views.
  • Automating the creation of persistent store configurations during app initialization.

Key capabilities

  • Defines and registers custom model classes using SwiftData annotations.
  • Configures and manages persistent stores for local data retention.
  • Executes fetch requests to retrieve specific entities or relationships.
  • Handles background tasks and context management for data mutations.

Example prompts

  • "Create a SwiftData model for a User entity with fields for name, email, and an array of posts."
  • "Write the code to configure a persistent store using SwiftData in my iOS app's App entry point."
  • "Fetch all active users from the database and filter them by registration date using SwiftData fetch requests."

Tips & gotchas

Ensure your Xcode version supports SwiftData, as it is a newer framework replacing Core Data. When defining models, remember that SwiftData requires specific conformance to @Model rather than the older NSManagedObject.
