Sample programs for OpenCV and Swift and iOS and macOS.

Those projects uses OpenCV version 3.3.0. However, OpenCV binary isn't include in thorse projects. You can get OpenCV binary by following steps.

1. Download opencv-3.3.0-ios-framework.zip from https://github.com/opencv/opencv/releases/download/3.3.0/opencv-3.3.0-ios-framework.zip.
2. Unpack the file.
3. Copy opencv2.framework into OpenCVSample_iOS directory.

If using above the binary, the linker may report many warnings such 'direct access in function '___cxx_global_var_init' from file...' on build. :-(

1. Prepare CMake. (e.g. port install cmake)
2. Download opencv-3.3.0.zip from https://github.com/opencv/opencv/archive/3.3.0.zip.
3. Prepare a working directory. (e.g. mkdir ~/foo)
4. Unpack the file into the working directory.
5. Open terminal at the working directory. (e.g. cd ~/foo)
6. Run a build script. python opencv-3.3.0/platforms/osx/build_framework.py osx
7. Copy osx/opencv2.framework into OpenCVSample_OSX directory.

• macOS 10.12.6 (Recommended)
• iOS 11.0 (Recommended)
• Xcode 9.0
• Swift 4.0
