#!/usr/bin/env bash

# Build native-devtools-ios dylibs for Argent.
# ObjC source lives in the argent-private submodule at packages/argent-private.
# Run from the workspace root: bash packages/native-devtools-ios/scripts/build.sh [dev|release]
# Or from this package: bash scripts/build.sh [dev|release]
#
# Usage: build.sh [dev|release]
#   mode: dev (fast) or release (optimized, optional signing). Default: release.
#
# Environment:
#   PREBUILT_NATIVE_DEVTOOLS_IOS  - if set, copy this path to dylibs/ instead of building (CI on non-macOS)
#   PREBUILT_KEYBOARD_PATCH       - same for keyboard patch dylib
#   PREBUILT_INJECTION_BOOTSTRAP  - same for bootstrap dylib
#   Release signing: set IDENTITY (or CODESIGN_IDENTITY), or for CI keychain import set
#     CERTIFICATE, PRIVATE_KEY_BASE64, PRIVATE_KEY_PASSWORD, KEYCHAIN_PASSWORD, IDENTITY.
