| # Build opencv2.xcframework from source using a convenience script provided in | ||
| # OPENCV sources and zip the xcframework. We only build the modules required by MediaPipe by specifying | ||
| # the modules to be ignored as command line arguments. | ||
| # We also specify the simulator and device architectures we are building for. | ||
| # Currently we only support iOS arm64 (M1 Macs) and x86_64(Intel Macs) simulators | ||
| # and arm64 iOS devices. | ||
| # Bitcode and Swift support. Swift support will be added in when the final binary | ||
| # for MediaPipe iOS Task libraries are built. Shipping with OPENCV built with | ||
| # Swift support throws linker errors when the MediaPipe framework is used from | ||
| # an iOS project. | ||
| # When building on M1 Macs, cmake version cannot be higher than 3.24.0. This is | ||
| # is mentioned in an open issue in the opencv github repo. | ||
