# 🤖 Xcode Cloud post-clone hook.
#
# The Xcode project is NOT committed to this repo — it is generated from
# ios/project.yml by XcodeGen (see ios/.gitignore). Xcode Cloud clones the repo
# and then expects to find ios/LChat.xcodeproj, so we regenerate it here, right
# after the clone and before dependency resolution + the build.
#
# LOCATION MATTERS: Xcode Cloud only runs ci_scripts/ when it sits next to the
# Xcode project/workspace. The project lives in ios/, so this folder must be
# ios/ci_scripts/ — NOT the repo root. (A repo-root ci_scripts is silently
# ignored for a subdirectory project, which looks like "the hook never ran".)
#
# Xcode Cloud runs this from the ci_scripts/ directory and exports
# CI_PRIMARY_REPOSITORY_PATH pointing at the cloned checkout root. Homebrew is
# preinstalled on the runners, so we install XcodeGen with it.
#
# Scope: iOS only for now (scheme "LChat"). The Mac scheme (LChatMac) pulls in
# Sparkle and an "Embed eleven CLI" step that shells out to `go build`; when we
# add Mac to Xcode Cloud this script will also need to install Go 1.25. Left out
# deliberately until then.

# Xcode Cloud's build step runs with automatic package resolution DISABLED
# (environment-wide), so it demands a Package.resolved already inside the
# project and refuses to resolve one itself. Our .xcodeproj is generated fresh
# (and gitignored), and we can't resolve on the runner either (same disabled
# state — `xcodebuild -resolvePackageDependencies` exits 74 there). So we ship a
# committed Package.resolved next to this script and stage it into the generated
# workspace. Xcode Cloud then finds it and never needs to resolve.
