# build-ios.sh — gomobile bind sing-box libbox → dist/ios/Libbox.xcframework
#
# 用法: ./build-ios.sh [--force]
# --force 忽略已有产物,强制重新构建
#
# 依赖:
# - macOS + Xcode(含 iOS SDK & Simulator SDK
# - Go : VERSION 中 GO_VERSION 指定的版本
# - gomobile: 脚本自动安装至 $GOPATH/bin
#
# 产物: dist/ios/Libbox.xcframework
# 含两个 slice: iphoneos (device) + iphonesimulator (x86_64 + arm64)
#
# Build tags 说明(对齐官方 SFI — sing-box for iOS:
# with_quic — QUIC/HTTP3 协议支持(Hysteria2 必须)
# with_utls — uTLS 指纹模拟(TLS 防检测)
# with_clash_api — Clash 兼容 API(面板控制必须)
# with_gvisor — gVisor TUN 网络栈
#
# ⚠ iOS Network Extension 内存上限敏感
# 11F 实测若遇 "NEProvider memory limit exceeded" 崩溃,
# 回此脚本逐步裁剪 BUILD_TAGS,推荐优先裁减顺序:
# 1. 去掉 with_grpc → 减约 4 MB(需 gRPC 入站时保留)
# 2. 去掉 with_gvisor → 减约 2 MB(失去 gVisor TUN stack 回退,改用系统栈)
# 3. 去掉 with_quic → 仅在完全不使用 Hysteria2/QUIC 时考虑
# 裁减后执行 ./build-ios.sh --force 重出包,重新接入 Flutter 工程(见 11F)。
