Build universal iOS static library in xcode for simulator and real device

Views: 9241 | Add Comments

The default static library target in Xcode does not support iPhone simulator and real iPhone device at once. You have to build your static library for others to use on simulator, and build another for real device.

With an Aggregate target, you can mix the two library together in one .a file. Here’s the run script for the Aggregate target:

# define output folder environment variable

# Step 1. Build Device and Simulator versions
xcodebuild -target Target -configuration ${CONFIGURATION} -sdk iphoneos  BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}"
xcodebuild -target Target -configuration ${CONFIGURATION} -sdk iphonesimulator -arch x86_64 -arch i386 BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}"

# make sure the output directory exists

# Step 2. Create universal binary file using lipo
lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/lib${PROJECT_NAME}.a" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/lib${PROJECT_NAME}.a" "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/lib${PROJECT_NAME}.a"

# Last touch. copy the header files. Just for convenience
