# add for iOS universal binary by libedax4dart. 2025/11/12
# Ref: https://blog.kishikawakatsumi.com/entry/2018/12/25/122315
# Builds universal iOS dylib supporting both simulator (x86_64) and device (arm64)
# The universal dylib is created using lipo and preserves platform info per-architecture
# Builds XCFramework supporting simulator (x86_64 Intel + arm64 Apple Silicon) and device (arm64)
# Note: lipo cannot combine simulator and device arm64 binaries into one fat binary
# Creates XCFramework bundle at ../bin/libedax.ios.xcframework containing:
# - Simulator framework: Universal binary (x86_64 + arm64)
# - Device framework: Single architecture (arm64)
#
# You should codesign the dylib to bundle iOS app. Ref: https://kan-kikuchi.hatenablog.com/entry/Xcode__Library_Validation
# You should codesign the framework to bundle iOS app. Ref: https://kan-kikuchi.hatenablog.com/entry/Xcode__Library_Validation
# example:
# codesign -f -s "Apple Development: Hoge Fuga (ABCDEF123)" '/path/to/libedax.ios.dylib'
# codesign -f -s "Apple Development: Hoge Fuga (ABCDEF123)" '../bin/libedax.ios.xcframework'
