Fixes for Swift troubles * Remove NS_SWIFT_NAME override for Point, Rect, and Size due to Darwin namespace conflict * Fix swift_type overrides in objc generator * Add backwards compatibility Swift typealiases for Point, Rect, Size * Add disable-swift build option to iOS/macOS builds * Add import directive to swift source when building with disable-swift Co-authored-by: Chris Ballinger <cballinger@rightpoint.com>

"""
|
|
The script builds OpenCV.framework for iOS.
|
|
The built framework is universal, it can be used to build app and run it on either iOS simulator or real device.
|
|
|
|
Usage:
|
|
./build_framework.py <outputdir>
|
|
|
|
By cmake conventions (and especially if you work with OpenCV repository),
|
|
the output dir should not be a subdirectory of OpenCV source tree.
|
|
|
|
Script will create <outputdir>, if it's missing, and a few its subdirectories:
|
|
|
|
<outputdir>
|
|
build/
|
|
iPhoneOS-*/
|
|
[cmake-generated build tree for an iOS device target]
|
|
iPhoneSimulator-*/
|
|
[cmake-generated build tree for iOS simulator]
|
|
{framework_name}.framework/
|
|
[the framework content]
|
|
samples/
|
|
[sample projects]
|
|
docs/
|
|
[documentation]
|
|
|
|
The script should handle minor OpenCV updates efficiently
|
|
- it does not recompile the library from scratch each time.
|
|
However, {framework_name}.framework directory is erased and recreated on each run.
|
|
|
|
Adding --dynamic parameter will build {framework_name}.framework as App Store dynamic framework. Only iOS 8+ versions are supported.
