What it does

Swift iOS is an agent skill from WrongStack/WrongStack. Build and upgrade native iOS applications with Swift, SwiftUI/UIKit and correct lifecycle/concurrency ownership. Use when implementing native screens, platform integrations or Swift migrations; verify toolchain, deployment target and device behavior separately.

Its SKILL.md is about 830 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile, covering iOS development. It works with iOS and SwiftUI. The repository describes itself as: An AI coding agent that reads your code, edits files, runs commands, and reasons through bugs — across a terminal REPL, a full-screen TUI, and a browser UI, while you keep your… The licence is MIT.

When your agent uses it

  • Implementing native screens
  • Platform integrations
  • Swift migrations
  • Verify toolchain

Example prompts

  • “/swift-ios”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Inspect project/schemes, deployment targets, entitlements and package/toolchain pins.
  2. Keep UI state ownership explicit and isolate UI mutations to the appropriate actor.
  3. Scope Tasks, observers and delegates to lifecycle; cancellation and late completion must respect owner replacement.
  4. Use secure platform storage/permissions with denied/revoked states and server-side authorization.
  5. Match native navigation, dynamic type, safe areas and accessibility rather than copying desktop geometry.
  6. Do not label a simulator build as signed-device or App Store release proof.

What it can do on your machine

Read from SKILL.md and the folder at commit a744bdc. 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.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • swift.org
    • developer.apple.com

    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 iOS loads about 826 tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 287 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~826

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.

Selection card

  • Task: Build SwiftUI and Apple platform features. / TR: SwiftUI ve Apple platform özellikleri kur.
  • Start: Identify the platform, screen, device and native integration boundary.
  • Finish: apply the acceptance checks below; report observed results and unresolved constraints.

Overview

Build and upgrade native iOS applications with Swift, SwiftUI/UIKit and correct lifecycle/concurrency ownership.

Checked stable Swift target: 6.4.0 on 2026-10-09. Xcode/SDK, Swift language mode and minimum deployment OS are separate constraints; verify current supported combinations before migration.

Rules

  1. Inspect project/schemes, deployment targets, entitlements and package/toolchain pins.
  2. Keep UI state ownership explicit and isolate UI mutations to the appropriate actor.
  3. Scope Tasks, observers and delegates to lifecycle; cancellation and late completion must respect owner replacement.
  4. Use secure platform storage/permissions with denied/revoked states and server-side authorization.
  5. Match native navigation, dynamic type, safe areas and accessibility rather than copying desktop geometry.
  6. Do not label a simulator build as signed-device or App Store release proof.

Workflow

  1. Trace screen/model/service ownership and current SwiftUI/UIKit conventions.
  2. Verify stable toolchain and migration effects on concurrency and packages.
  3. Implement the feature with intentional actor/lifecycle boundaries.
  4. Test background/resume, cancellation, permissions, large text and navigation.
  5. Build/test the selected scheme and verify representative device behavior.

Before returning

Toolchain/language/deployment targets explicit; actor/lifecycle state safe; simulator/device/signing evidence distinguished.

Sources

Versioned facts checked 2026-10-09; refresh authoritative sources before new installs/upgrades. Swift releases, Apple development.

Skills in scope

  • mobile-design — design and implement mobile interfaces for touch, keyboards, safe areas and native navigation.
  • mobile-performance — measure and improve mobile startup, scrolling, animation and resource usage on representative devices.
  • mobile-release — prepare and verify signed mobile releases, test-channel distribution and store submission artifacts.
  • authentication-sessions — implement application sign-in, sessions and identity integration with explicit account/tenant authorization.

With the skills CLI, run `npx skills add WrongStack/WrongStack --skill swift-ios -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-ios, .gemini/skills/swift-ios, .github/skills/swift-ios and .opencode/skills/swift-ios in your project.

What does Swift iOS need to run?

SKILL.md names no scripts, command-line tools or credentials: Swift iOS is instructions for the agent only.

Does Swift iOS access the network?

SKILL.md names 2 domains. As links in the text: swift.org and developer.apple.com. This is read from the text; nothing was executed.

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 iOS use?

Swift iOS is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Swift iOS use?

About 826 tokens (SKILL.md is roughly 3.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
