swift

swift is a skill for Claude Code, Codex from hmj1026/dhpk. It costs 71 tokens per session (929 once invoked), scanned A, original, MIT.

A development guide for Swift, the programming language used for Apple platforms, and for iOS apps built with it. It covers SwiftUI interfaces, asynchronous tests, privacy settings, Xcode and Swift Package Manager builds, and app icons.

In plain words
What is it for?
Use it to implement or review Swift and iOS features, configure builds and tests, handle privacy or concurrency settings, or prepare asset-catalog icons.
Why use it?
Swift and iOS behaviour depends on the project’s deployment target, language settings, and package or Xcode configuration. This checks those constraints before suggesting code or build changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

swift scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/iconify_gen.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Swift

Use $swift <task>; optional test, build, and icon actions select the same internal task paths. Complete the requested task with the smallest local reference set; specialist references are procedures, not independent skills.

Resolve the target before loading

  1. Establish the target package, Xcode project/scheme, or asset catalog from the request and project evidence. Ask and wait when a monorepo has several plausible targets. An intentional explicit target/version override wins; report the override separately from the observed configuration.
  2. For version-sensitive work read the target's SWIFT_VERSION, SWIFT_STRICT_CONCURRENCY, deployment target, and applicable Package.swift tools version. The installed swift --version is execution-environment evidence, not target compatibility. Preserve the precision of the evidence.
  3. Missing, conflicting, or broad incompatible constraints require a question and an answer before version-specific references or dependent actions. A migration needs an explicit destination version. For several destinations, group resources, changes, and verification by target.

Select only the task's resources

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

swift is a skill published in the GitHub repository hmj1026/dhpk (2 stars, last pushed today), licensed MIT. It adds 71 tokens to every session and 929 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-16.
