Automated safety checks
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 dpearson2699/swift-ios-skills at 8d90fd121a.
The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill
What it does
This skill provides guidance and techniques for optimizing SwiftUI applications. It helps identify performance bottlenecks, such as excessive view updates or inefficient data handling, and offers solutions to improve rendering speed and overall responsiveness. The goal is to create smoother, more efficient user experiences within iOS apps built with SwiftUI.
When to use it
- Slow UI Rendering: When animations are jerky or views take too long to appear.
- High Memory Usage: When profiling reveals excessive memory consumption in a SwiftUI app.
- Complex List Views: Optimizing performance of large lists or grids where rendering efficiency is critical.
- Debugging Performance Issues: To help pinpoint and resolve specific areas causing slowdowns within the application.
Key capabilities
- Performance Profiling Guidance
- View Optimization Techniques
- Data Handling Efficiency Strategies
- Rendering Pipeline Analysis
Example prompts
- "How can I optimize a SwiftUI list view with 1000 items?"
- "What are some common causes of slow rendering in SwiftUI?"
- "Suggest ways to reduce memory usage in my SwiftUI app."
Tips & gotchas
This skill assumes basic familiarity with SwiftUI concepts and development. It's most effective when used alongside Xcode’s profiling tools for accurate bottleneck identification.
