• Add the static library target to the ‘Target Dependencies’.

Step 3: Build the ‘Other’ Platform

• To build the ‘Other’ platform, use a ‘Run Script’ phase.

• Add a new ‘Run Script’ build phase to your ‘Aggregate’ target and paste the following code.

set -e
 
set -e
 
set +u
 
# Avoid recursively calling this script.
 
if [[ $SF_MASTER_SCRIPT_RUNNING ]]
 
then
 
   exit 0
 
fi
 
set -u
 
export SF_MASTER_SCRIPT_RUNNING=1
 
  
 
SF_TARGET_NAME=${PROJECT_NAME}
 
SF_EXECUTABLE_PATH="lib${SF_TARGET_NAME}.a"
 
SF_WRAPPER_NAME="${SF_TARGET_NAME}.framework"
 
  
 
# The following conditionals come from
 
# https://github.com/kstenerud/iOS-Universal-Framework
 
  
 
if [[ "$SDK_NAME" =~ ([A-Za-z]+) ]]
 
then
 
   SF_SDK_PLATFORM=${BASH_REMATCH[1]}
 
else
 
   echo "Could not find platform name from SDK_NAME: $SDK_NAME"
 
   exit 1
 
fi
 
  
 
if [[ "$SDK_NAME" =~ ([0-9]+.*$) ]] then
 
   SF_SDK_VERSION=${BASH_REMATCH[1]}
 
else
 
   echo "Could not find sdk version from SDK_NAME: $SDK_NAME"
 
   exit 1
 
fi
 
  
 
if [[ "$SF_SDK_PLATFORM" = "iphoneos" ]]
 
then
 
   SF_OTHER_PLATFORM=iphonesimulator
 
else
 
   SF_OTHER_PLATFORM=iphoneos
 
fi
 
  
 
if [[ "$BUILT_PRODUCTS_DIR" =~ (.*)$SF_SDK_PLATFORM$ ]]
 
then
 
   SF_OTHER_BUILT_PRODUCTS_DIR="${BASH_REMATCH[1]}${SF_OTHER_PLATFORM}"
 
else
 
   echo "Could not find platform name from build products directory: $BUILT_PRODUCTS_DIR"
 
   exit 1
 
fi
 
  
 
# Build the other platform.
 
xcodebuild -project "${PROJECT_FILE_PATH}" -target "${TARGET_NAME}" -configuration "${CONFIGURATION}" -sdk ${SF_OTHER_PLATFORM}${SF_SDK_VERSION} BUILD_DIR="${BUILD_DIR}" OBJROOT="${OBJROOT}" BUILD_ROOT="${BUILD_ROOT}" SYMROOT="${SYMROOT}" $ACTION
 
  
 
# Smash the two static libraries into one fat binary and store it in the .framework
 
lipo -create "${BUILT_PRODUCTS_DIR}/${SF_EXECUTABLE_PATH}" "${SF_OTHER_BUILT_PRODUCTS_DIR}/${SF_EXECUTABLE_PATH}" -output "${BUILT_PRODUCTS_DIR}/${SF_WRAPPER_NAME}/Versions/A/${SF_TARGET_NAME}"
 
  
 
# Copy the binary to the other architecture folder to have a complete framework in both.
 
cp -a "${BUILT_PRODUCTS_DIR}/${SF_WRAPPER_NAME}/Versions/A/${SF_TARGET

Step 4: Build to verify

• Now  you have set up an environment to build a distributable <project_name>.framework

• Build the ‘Aggregate’ target

• Expand the Products group in X-Code, right click the static library and click ‘Show in Finder’

Note: If this doesn’t open Finder to show the static library, then try opening

~/Library/Developer/Xcode/DerivedData/<project name>/Build/Products/Debug-iphonesimulator/.

• In this folder you will find your <project_name>.framework folder.

You can now share the <project_name>.framework among other iOS app developers.
