Pre-build VISP for iOS.

This is done on a M3 computer with macOS 14 with Xcode 15. The architechture of the iOS and simulator will both be arm64.

Make a root folder

mkdir visp-local
cd visp-local

Get the source code and checkout to the specific version. v3.6.0 is used at the moment.

git clone https://github.com/lagadic/visp.git
cd visp
git checkout v3.6.0

cd ..
mkdir build_ios
cd build_ios
python3 ../visp/platforms/ios/build_framework.py \
. \
--iphoneos_archs=arm64 \
--iphoneos_deployment_target=17 \
--disable-bitcode \
--build_only_specified_archs

The above command will generate a folder under build_ios with the name visp3.framework.

cd ..
mkdir build_simulator
cd build_simulator
python3 ../visp/platforms/ios/build_framework.py \
. \
--iphonesimulator_archs=arm64 \
--iphoneos_deployment_target=17 \
--disable-bitcode \
--build_only_specified_archs

Similarly, the above command generates a visp3.framework folder under the build_simulator folder.

cd ..
xcodebuild -create-xcframework \
-framework build_ios/visp3.framework/ \
-framework build_simulator/visp3.framework \
-output "visp3.xcframework"

The above command generates the visp3.xcframework file. Use macOS to create a .zip file.

Currently use manual releases.

First, do all the updates, including Package.swift file. Specify the URL in Pakcage.swfit without creating the actual release. Copy the visp3.xcframework.zip file to the repo folder. Use the following command to calculate the checksum.

shasum -a 256 visp3.xcframework.zip

Past the checksum to Package.swfit.

Edit the README if needed. Then make a commit and push to the main branch.

Then do the following

gh release create v3.6.0 --notes "Pre-build of VISP 3.6.0." visp3.xcframework.zip

The above command creates a new release and add a v3.6.0 tag to the GitHub repo.
