Making Universal iOS Static Library

  1. Make Simple iOS Static Library StaticLibrary

  2. Add Aggregator target to our static library project

    1. Push the '+' button where is left bottom side Aggregate

AggregateResult

  1. Adding New Run Script Phase RunscriptPhase

  2. Attached the script to the blank(Reference: Annex A) binShell


Using iOS Static Library in our Project

  1. Make Structure
    staticLibraryStructure
  2. Set Header Search Path
    iOSStaticLibHeaderSearchPath
  3. Make Briding Header File: [projectName]-briding-Header.h makingBridingHeader
    bridingHeaderContent
  4. Set Objective-C Briding Header setBridingHeader

Annex A - bin/sh code

# define output folder environment variable
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal

# Step 1. Build Device and Simulator versions
xcodebuild -target ${PROJECT_NAME} ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos  BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}"
xcodebuild -target ${PROJECT_NAME} -configuration ${CONFIGURATION} -sdk iphonesimulator -arch x86_64 -arch i386 -arch armv7 -arch armv7s -arch arm64 BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}"

# make sure the output directory exists
mkdir -p "${UNIVERSAL_OUTPUTFOLDER}"
 
# 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"
 
echo "Universal library can be found here:"
echo ${UNIVERSAL_OUTPUTFOLDER}/lib${PROJECT_NAME}.a

# Last touch. copy the header files. Just for convenience
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphoneos/include" "${UNIVERSAL_OUTPUTFOLDER}/"
