asc screenshots pipeline (xcodebuild -> AXe -> frame -> asc)

Use this skill for agent-driven screenshot workflows where the app is built and launched with Xcode CLI tools, UI is driven with AXe, and screenshots are uploaded with asc.

Current scope

• Implemented now: build/run, AXe plan capture, frame composition, and upload.
• Device discovery is built-in via asc screenshots list-frame-devices.
• Local screenshot automation commands are experimental in asc cli.
• Framing is pinned to Koubou 0.18.0 for deterministic output.
• Feedback/issues: https://github.com/rudrankriyam/App-Store-Connect-CLI/issues/new/choose

Defaults

• Settings file: .asc/shots.settings.json
• Capture plan: .asc/screenshots.json
• Raw screenshots dir: ./screenshots/raw
• Framed screenshots dir: ./screenshots/framed
• Default frame device: iphone-air

1) Create settings JSON first

Create or update .asc/shots.settings.json:

{
  "version": 1,
  "app": {
    "bundle_id": "com.example.app",
    "project": "MyApp.xcodeproj",
    "scheme": "MyApp",
    "simulator_udid": "booted"
  },
  "paths": {
    "plan": ".asc/screenshots.json",
    "raw_dir": "./screenshots/raw",
    "framed_dir": "./screenshots/framed"
  },
  "pipeline": {
    "frame_enabled": true,
    "upload_enabled": false
  },
  "upload": {
    "version_localization_id": "",
    "device_type": "IPHONE_65",
    "source_dir": "./screenshots/framed"
  }
}

If you intentionally skip framing, set:

• "frame_enabled": false
• "upload.source_dir": "./screenshots/raw"

2) Build and run app on simulator

Use Xcode CLI for build/install/launch:

xcrun simctl boot "$UDID" || true

xcodebuild \
  -project "MyApp.xcodeproj" \
  -scheme "MyApp" \
  -configuration Debug \
  -destination "platform=iOS Simulator,id=$UDID" \
  -derivedDataPath ".build/DerivedData" \
  build

xcrun simctl install "$UDID" ".build/DerivedData/Build/Products/Debug-iphonesimulator/MyApp.app"
xcrun simctl launch "$UDID" "com.example.app"

Use xcodebuild -showBuildSettings if the app bundle path differs from the default location.

3) Capture screenshots with AXe (or asc screenshots run)

Prefer plan-driven capture:

asc screenshots run --plan ".asc/screenshots.json" --udid "$UDID" --output json

Useful AXe primitives during plan authoring:

axe describe-ui --udid "$UDID"
axe tap --id "search_field" --udid "$UDID"
axe type "wwdc" --udid "$UDID"
axe screenshot --output "./screenshots/raw/home.png" --udid "$UDID"

Minimal .asc/screenshots.json example:

{
  "version": 1,
  "app": {
    "bundle_id": "com.example.app",
    "udid": "booted",
    "output_dir": "./screenshots/raw"
  },
  "steps": [
    { "action": "launch" },
    { "action": "wait", "duration_ms": 800 },
    { "action": "screenshot", "name": "home" }
  ]
}

4) Frame screenshots with asc screenshots frame

asc cli pins framing to Koubou 0.18.0. Install and verify before running framing steps:

pip install koubou==0.18.0
kou --version  # expect 0.18.0
# If Koubou reports missing device frames, run once with network access:
kou setup-frames

List supported frame device values first:

asc screenshots list-frame-devices --output json

Frame one screenshot (defaults to iphone-air):

asc screenshots frame \
  --input "./screenshots/raw/home.png" \
  --output-dir "./screenshots/framed" \
  --device "iphone-air" \
  --output json

Supported --device values:

• iphone-air (default)
• iphone-17-pro
• iphone-17-pro-max
• iphone-16e
• iphone-17
• mac

5) Upload screenshots with asc

Generate and review artifacts before upload:

asc screenshots review-generate --framed-dir "./screenshots/framed" --output-dir "./screenshots/review"
asc screenshots review-open --output-dir "./screenshots/review"
asc screenshots review-approve --all-ready --output-dir "./screenshots/review"

Upload from the configured source directory (default ./screenshots/framed when framing is enabled):

asc screenshots upload \
  --version-localization "LOC_ID" \
  --path "./screenshots/framed" \
  --device-type "IPHONE_65" \
  --output json

List or validate before upload when needed:

asc screenshots sizes --output table
asc screenshots list --version-localization "LOC_ID" --output table

Agent behavior

• Always confirm exact flags with --help before running commands.
• Re-check command paths with asc screenshots --help because screenshot commands are evolving quickly.
• Keep outputs deterministic: default to JSON for machine steps.
• Prefer asc screenshots list-frame-devices --output json before selecting a frame device.
• Ensure screenshot files exist before upload.
• Use explicit long flags (--app, --output, --version-localization, etc.).
• Treat screenshot-local automation as experimental and call it out in user-facing handoff notes.
• If framing fails with a version error, re-install pinned Koubou: pip install koubou==0.18.0.
• If framing fails because device frames are missing, run kou setup-frames once with network access.

6) Multi-locale capture (optional)

Do not use xcrun simctl launch ... -e AppleLanguages for localization. -e is an environment variable pattern and does not reliably switch app language.

For this pipeline, use simulator-wide locale defaults per UDID. This works with asc screenshots capture, which relaunches the app internally.

# Map each locale to a dedicated simulator UDID.
# (Create these simulators once with `xcrun simctl create`.)
declare -A LOCALE_UDID=(
  ["en-US"]="UDID_EN_US"
  ["de-DE"]="UDID_DE_DE"
  ["fr-FR"]="UDID_FR_FR"
  ["ja-JP"]="UDID_JA_JP"
)

set_simulator_locale() {
  local UDID="$1"
  local LOCALE="$2"            # e.g. de-DE
  local LANG="${LOCALE%%-*}"   # de
  local APPLE_LOCALE="${LOCALE/-/_}" # de_DE

  xcrun simctl boot "$UDID" || true
  xcrun simctl spawn "$UDID" defaults write NSGlobalDomain AppleLanguages -array "$LANG"
  xcrun simctl spawn "$UDID" defaults write NSGlobalDomain AppleLocale -string "$APPLE_LOCALE"
}

for LOCALE in "${!LOCALE_UDID[@]}"; do
  UDID="${LOCALE_UDID[$LOCALE]}"
  echo "Capturing $LOCALE on $UDID..."
  set_simulator_locale "$UDID" "$LOCALE"

  xcrun simctl terminate "$UDID" "com.example.app" || true
  asc screenshots capture \
    --bundle-id "com.example.app" \
    --name "home" \
    --udid "$UDID" \
    --output-dir "./screenshots/raw/$LOCALE" \
    --output json
done

If you launch manually (outside asc screenshots capture), use app launch arguments:

xcrun simctl launch "$UDID" "com.example.app" -AppleLanguages "(de)" -AppleLocale "de_DE"

7) Parallel execution for speed

Run one locale per simulator UDID in parallel:

#!/bin/bash
# parallel-capture.sh

declare -A LOCALE_UDID=(
  ["en-US"]="UDID_EN_US"
  ["de-DE"]="UDID_DE_DE"
  ["fr-FR"]="UDID_FR_FR"
  ["ja-JP"]="UDID_JA_JP"
)

capture_locale() {
  local LOCALE="$1"
  local UDID="$2"
  local LANG="${LOCALE%%-*}"
  local APPLE_LOCALE="${LOCALE/-/_}"

  echo "Starting $LOCALE on $UDID"
  xcrun simctl boot "$UDID" || true
  xcrun simctl spawn "$UDID" defaults write NSGlobalDomain AppleLanguages -array "$LANG"
  xcrun simctl spawn "$UDID" defaults write NSGlobalDomain AppleLocale -string "$APPLE_LOCALE"
  xcrun simctl terminate "$UDID" "com.example.app" || true

  asc screenshots capture \
    --bundle-id "com.example.app" \
    --name "home" \
    --udid "$UDID" \
    --output-dir "./screenshots/raw/$LOCALE" \
    --output json

  echo "Completed $LOCALE"
}

for LOCALE in "${!LOCALE_UDID[@]}"; do
  capture_locale "$LOCALE" "${LOCALE_UDID[$LOCALE]}" &
done

wait
echo "All captures done. Now framing..."

Or use xargs with locale:udid pairs:

printf "%s\n" \
  "en-US:UDID_EN_US" \
  "de-DE:UDID_DE_DE" \
  "fr-FR:UDID_FR_FR" \
  "ja-JP:UDID_JA_JP" | xargs -P 4 -I {} bash -c '
    PAIR="{}"
    LOCALE="${PAIR%%:*}"
    UDID="${PAIR##*:}"
    LANG="${LOCALE%%-*}"
    APPLE_LOCALE="${LOCALE/-/_}"
    xcrun simctl boot "$UDID" || true
    xcrun simctl spawn "$UDID" defaults write NSGlobalDomain AppleLanguages -array "$LANG"
    xcrun simctl spawn "$UDID" defaults write NSGlobalDomain AppleLocale -string "$APPLE_LOCALE"
    xcrun simctl terminate "$UDID" "com.example.app" || true
    asc screenshots capture --bundle-id "com.example.app" --name "home" --udid "$UDID" --output-dir "./screenshots/raw/$LOCALE" --output json
  '

8) Full multi-locale pipeline example

#!/bin/bash
# full-pipeline-multi-locale.sh

declare -A LOCALE_UDID=(
  ["en-US"]="UDID_EN_US"
  ["de-DE"]="UDID_DE_DE"
  ["fr-FR"]="UDID_FR_FR"
  ["es-ES"]="UDID_ES_ES"
  ["ja-JP"]="UDID_JA_JP"
)

DEVICE="iphone-air"
RAW_DIR="./screenshots/raw"
FRAMED_DIR="./screenshots/framed"

# Step 1: Parallel capture with per-simulator locale defaults
for LOCALE in "${!LOCALE_UDID[@]}"; do
  (
    UDID="${LOCALE_UDID[$LOCALE]}"
    LANG="${LOCALE%%-*}"
    APPLE_LOCALE="${LOCALE/-/_}"

    xcrun simctl boot "$UDID" || true
    xcrun simctl spawn "$UDID" defaults write NSGlobalDomain AppleLanguages -array "$LANG"
    xcrun simctl spawn "$UDID" defaults write NSGlobalDomain AppleLocale -string "$APPLE_LOCALE"
    xcrun simctl terminate "$UDID" "com.example.app" || true

    asc screenshots capture \
      --bundle-id "com.example.app" \
      --name "home" \
      --udid "$UDID" \
      --output-dir "$RAW_DIR/$LOCALE" \
      --output json
    echo "Captured $LOCALE"
  ) &
done
wait

# Step 2: Parallel framing
for LOCALE in "${!LOCALE_UDID[@]}"; do
  (
    asc screenshots frame \
      --input "$RAW_DIR/$LOCALE/home.png" \
      --output-dir "$FRAMED_DIR/$LOCALE" \
      --device "$DEVICE" \
      --output json
    echo "Framed $LOCALE"
  ) &
done
wait

# Step 3: Generate review (single run, aggregates all locales)
asc screenshots review-generate \
  --framed-dir "$FRAMED_DIR" \
  --output-dir "./screenshots/review"

# Step 4: Upload (run per locale if needed)
for LOCALE in "${!LOCALE_UDID[@]}"; do
  asc screenshots upload \
    --version-localization "LOC_ID_FOR_$LOCALE" \
    --path "$FRAMED_DIR/$LOCALE" \
    --device-type "IPHONE_65" \
    --output json
done
