Build Xcode project for iOS device

Build the Xcode workspace or project under the current working directory for a physical iOS device. Uses a generic device destination (no specific UDID). Requires a configured signing team in the project — otherwise xcodebuild will fail with a code-signing error.

How to build

The shared agent-skill-xcode.el lives in the sibling xcode-shared directory at skills/xcode-shared/agent-skill-xcode.el in the emacs-skills plugin. All four /xcode-* skills load it from there.

emacsclient --eval "(progn (load \"/path/to/skills/xcode-shared/agent-skill-xcode.el\" nil t) (agent-skill-xcode-build-device :project-dir \"$(pwd)\"))"

The function:

• Locates the first .xcworkspace (preferred) or .xcodeproj in :project-dir.
• Picks a scheme via xcodebuild -list -json.
• Runs xcodebuild build -destination 'generic/platform=iOS'.
• Returns "Build succeeded: ..." on success, or "Build FAILED: ...\n--- last 40 lines ---\n..." on failure.

Rules

• Pass the agent's current working directory as :project-dir via $(pwd). Do not assume a hard-coded path.
• The shared elisp lives under xcode-shared/agent-skill-xcode.el — load it from there, not from this skill's directory.
• Run via the Bash tool with a single emacsclient --eval invocation.
• Report the returned status string verbatim on failure.
• If the failure mentions code signing, point the user to Xcode → target → Signing & Capabilities → Team. Don't try to fix signing automatically.
• If the user wants to also run the app on-device, suggest /xcode-run-device.
