## What it does

The skill implements marketing screenshot capture directly inside your app target rather than via XCUITest. Adding a UI test target to an existing project is fragile. In-app capture avoids touching `project.pbxproj` and cuts down launch overhead. The app builds once via `xcodebuild`, then runs iteratively in the simulator.

Execution relies on a DEBUG-only `MarketingCapture.swift` file. Launched with `-MarketingCapture 1`, a coordinator walks a list of `CaptureStep` entries, seeds mock data, and exports PNGs to the sandbox directory. Element captures use `ImageRenderer` to generate standalone components, such as widgets or cards, with clean transparency outside rounded corners. A shell script handles locale iteration using `-AppleLanguages` and `-AppleLocale`, extracting files through `simctl get_app_container`.

You need existing seed data or a seeder function before starting. If your app isolates widgets in a separate target, those view files must be accessible in the main target for `ImageRenderer` to reach them.

## When to use it
- capture localized SwiftUI screenshots across multiple locales
- render isolated widgets and cards with transparent backgrounds
- automate snapshot runs without setting up XCUITest targets
- extract assets directly from simulator sandbox containers

## Example prompts
- Set up automated marketing screenshots for our profile and checkout views across English and German
- Render isolated widget cards with transparent backgrounds for marketing assets
- Generate in-app screenshot automation using simctl and mock data seeding

# iOS Marketing Capture

## Overview

Automate reproducible marketing screenshot capture for a SwiftUI iOS app across multiple locales, with two parallel output streams:

1. **Full-screen captures** — every marketing-relevant screen, with deterministic seeded data, real status bar / safe-area chrome
2. **Element captures** — isolated renders of specific components (cards, widgets, charts) at any scale, with natural background inside rounded corners and transparency outside

This skill is the **capture** step. If the user also wants Apple-style marketing pages composited around the shots (device mockups, headlines, gradients), combine with the `app-store-screenshots` skill as a post-processing step.

## Core Approach

**In-app capture mode**, not XCUITest. This is a hard decision that trades off against Fastlane snapshot / XCUITest conventions, and it wins for almost every real project.

Why in-app over XCUITest:

- **No new test target.** Adding a UI test target to an existing Xcode project is fragile pbxproj surgery. Many projects have zero test targets and no xcodegen — adding one by hand is error-prone.
- **Faster iteration.** A UI test takes 30s+ to launch per run. In-app capture is just a relaunch of the installed binary.
- **No `xcodebuild test`.** The whole flow is `xcodebuild build` once, then `simctl launch` per locale. No test-bundle overhead.
- **Access to real app state.** You can call ViewModels, SwiftData, ImageRenderer, and `UIWindow.drawHierarchy` directly. XCUITest can only tap and read accessibility elements.
- **Element renders need in-process anyway.** `ImageRenderer` on widget views or isolated components must run inside the app process — there's no XCUITest equivalent.

How it works:

1. A DEBUG-only `MarketingCapture.swift` file lives in the main app target
2. When launched with `-MarketingCapture 1`, the app seeds data, then a coordinator walks a list of `CaptureStep`s — each step navigates, waits for settle, snapshots, and cleans up
3. PNGs are written to the app's sandbox `Documents/marketing/<locale>/` directory
```
