What it does
Swift Language is an agent skill from dpearson2699/swift-ios-skills. Apply modern Swift language patterns and idioms for non-concurrency, non-SwiftUI code. Covers if/switch expressions (Swift 5.9+), typed throws (Swift 6+), result builders, property wrappers, opaque and existential types (some vs any), guard patterns, Never type, Regex builders (Swift 5.7+), basic Codable shaping (CodingKeys, custom decoding, nested containers), modern collection APIs (count(where:), contains(where:), replacing()), basic FormatStyle usage, and string interpolation patterns. Use when writing core…
Its SKILL.md is about 3.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `evals/evals.json`, `references/swift-attributes-interop.md` and `references/swift-patterns-extended.md`).
It sits in Mobile, covering iOS development, API design and Internationalization. It works with Swift and SwiftUI. The repository describes itself as: Agent Skills for iOS 26+, Swift 6.3, SwiftUI, and modern Apple frameworks.
When your agent uses it
- Writing core Swift code involving generics
- Modern language features
- Route deep Codable to swift-codable
- Detailed formatting/localization to swift-formatstyle
Example prompts
- “/swift-language”
Workflow steps
10 steps, taken from the first numbered list in SKILL.md.
- Using any when some works. Default to some for return types and
- Manual loops or .filter { }.count instead of collection APIs. Use
- DateFormatter instead of FormatStyle. .formatted() is simpler,
- Force-unwrapping Codable decodes. Use decodeIfPresent with defaults
- Reordering preconditions during modernization. Use guard without moving
- Invalid @c signatures. Say UnsafeBufferPointer is a Swift struct/value
- Ignoring typed throws. When a function has a single, clear error type,
- Overusing property wrappers. A computed property is simpler when there
- Underspecifying Never. For Result or throws(Never), write the caveat explicitly: Never does not implicitly conform to arbitrary protocols…
- Owning sibling implementation. Name the owner skill and stop. Avoid
What it can do on your machine
Read from SKILL.md and the folder at commit 8d90fd1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are swift).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Swift Language loads about 3.8k tokens when it runs, and up to ~8.1k if it reads all its reference files. Until then it costs about 190 tokens; SKILL.md has 1,068 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,068 words (~3,801 tokens).
“Apply current Swift language syntax without changing behavior or evaluation order. Route deep decoding to swift-codable, formatting to swift-formatstyle, naming to swift-api-design-guidelines, concurrency to swift-concurrency, and SwiftUI state/view work to swiftui-patterns.”

Can I use Swift Language in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add dpearson2699/swift-ios-skills --skill swift-language -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/swift-language, .gemini/skills/swift-language, .github/skills/swift-language and .opencode/skills/swift-language in your project.
What does Swift Language need to run?
SKILL.md names no scripts, command-line tools or credentials: Swift Language is instructions for the agent only.
Does Swift Language access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Swift Language safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Swift Language use?
Swift Language has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Swift Language use?
About 3.8k tokens (SKILL.md is roughly 15k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 4.3k tokens, read only when the agent opens those files.
