#!/usr/bin/env bash
# ---------------------------------------------------------------------------
#  Generates an iOS Xcode project for Torque2D from the CMake build (macOS).
#
#  Just double-click this file in Finder. It creates the project under
#  build/ios and opens it in Xcode. You do NOT need to know anything about
#  CMake; you only need CMake and full Xcode installed. In Xcode, pick the
#  "Torque2D" scheme + an iOS Simulator destination, then Build (Cmd-B) and
#  Run (Cmd-R).
#
#  This targets the arm64 iOS SIMULATOR (no code-signing needed for a first
#  pass). For a device build, drop the iphonesimulator sysroot, set a
#  development team, and flip CODE_SIGNING_ALLOWED — see
#  cmake/BUILD-PLATFORM-NOTES.md (iOS round).
#
#  (You may need to `chmod +x generate-xcode-ios.command` once, since the
#  executable bit is not preserved on a Windows checkout.)
#
#  HEADS-UP: the iOS and macOS builds both emit Torque2D_DEBUG.app to the repo
#  root, with INCOMPATIBLE layouts (iOS = flat; macOS = Contents/). Building one
#  then the other in the same checkout corrupts the bundle. Run
#  `rm -rf Torque2D_DEBUG.app` when switching between the iOS and macOS builds.
#
#  STATUS: builds & links for the arm64 simulator; runtime not yet verified.
