build-iphone-appsBuild professional native iPhone apps in Swift with SwiftUI and UIKit.
Build Iphone Apps is an agent skill from glittercowboy/taches-cc-resources. Build professional native iPhone apps in Swift with SwiftUI and UIKit. Full lifecycle - build, debug, test, optimize, ship. CLI-only, no Xcode. Targets iOS 26 with iOS 18 compatibility.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 27 other files, including reference files (for example `references/accessibility.md`, `references/app-architecture.md` and `references/app-icons.md`).
It sits in Mobile, covering iOS development. It works with iOS, Xcode and SwiftUI. The repository describes itself as: A collection of my favorite custom Claude Code resources to make life easier. The licence is MIT.
6 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 1757615. It shows what the files ask for, not the result of running them.
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.
Shell commands in SKILL.md call:
xcrunxcodebuildFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Build Iphone Apps loads about 1.3k tokens when it runs, and up to ~56k if it reads all its reference files. Until then it costs about 51 tokens; SKILL.md has 572 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.
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.

The user is the product owner. Claude is the developer.
The user does not write code. The user does not read code. The user describes what they want and judges whether the result is acceptable. Claude implements, verifies, and reports outcomes.
Never say "this should work." Prove it:
xcodebuild -destination 'platform=iOS Simulator,name=iPhone 16' build 2>&1 | xcsift
xcodebuild test -destination 'platform=iOS Simulator,name=iPhone 16'
xcrun simctl boot "iPhone 16" && xcrun simctl launch booted com.app.bundleIf you didn't run it, you don't know it works.
| Question | How to Answer |
|---|---|
| Does the logic work? | Write test, see it pass |
| Does it look right? | Launch in simulator, user looks at it |
| Does it feel right? | User uses it |
| Does it crash? | Test + launch |
| Is it fast enough? | Profiler |
Tests verify correctness. The user verifies desirability.
Bad: "I refactored DataService to use async/await with weak self capture"
Good: "Fixed the memory leak. leaks now shows 0 leaks. App tested stable for 5 minutes."
The user doesn't care what you changed. The user cares what's different.
Change → Verify → Report → Next changeNever batch up work. Never say "I made several changes." Each change is verified before the next. If something breaks, you know exactly what caused it.
Unclear requirement? Ask now. Multiple valid approaches? Ask which. Scope creep? Ask if wanted. Big refactor needed? Ask permission.
Wrong: Build for 30 minutes, then "is this what you wanted?" Right: "Before I start, does X mean Y or Z?"
Every stopping point = working state. Tests pass, app launches, changes committed. The user can walk away anytime and come back to something that works. </essential_principles>

Build professional native iPhone apps in Swift with SwiftUI and UIKit. Build Iphone Apps is an agent skill from glittercowboy/taches-cc-resources. Build professional native iPhone apps in Swift with SwiftUI and UIKit.
Build Iphone Apps fits situations like: tasks that involve iOS development.
Run `npx skills add glittercowboy/taches-cc-resources --skill build-iphone-apps -a claude-code`. Or copy the skill folder (skills/expertise/iphone-apps in glittercowboy/taches-cc-resources) into .claude/skills/build-iphone-apps in your project. Claude Code loads it when a task matches its description.
Run `npx skills add glittercowboy/taches-cc-resources --skill build-iphone-apps -a codex`. Or copy the skill folder (skills/expertise/iphone-apps in glittercowboy/taches-cc-resources) into .agents/skills/build-iphone-apps in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add glittercowboy/taches-cc-resources --skill build-iphone-apps -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/build-iphone-apps, .gemini/skills/build-iphone-apps, .github/skills/build-iphone-apps and .opencode/skills/build-iphone-apps in your project.
Going by SKILL.md and its folder, Build Iphone Apps needs the command-line tools its instructions call (xcrun and xcodebuild).
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.
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.
Build Iphone Apps is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.3k tokens (SKILL.md is roughly 5.4k 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 55k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Build Iphone Apps: Update Swiftui APIs (AvdLee/SwiftUI-Agent-Skill, 3.7k stars), SwiftUI Design Skill (Wholiver/swiftui-design-skill, 204 stars), Swiftui Iphone Duo (FloWritesCode/fwc-swiftui-skills, 407 stars) and Audit Xcode Security Settings (superagents-lab/xcode27-skills, 341 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
