How to create universal framework in xcode6

I know how to create a framework in Xcode 5. But in Xcode 6 how to combine both a simulator framework & a device framework? When I try to combine I get a code signing error. When I use lipo to combine both framework, I also get an error.

Error: Command /bin/sh failed with exit code 65

My solution to create universal framework in xcode6.

Try these steps:

Step 1:

File—> 
    New —> 
       Project —> 
           Framework & Library —> 
               Next —> 
                      Product Name

Step 2: Create custom class files

Step 3:

Target -> 
       Build phase -> 
           Headers, 

Makes all header files into public. Now build in simulator & device.

Step 4:

File ->
    New ->
           Target ->
               iOS ->
                      Other -> 
                          Aggrigate ->somename eg: framework

Step 5:

From Targets —> 
    Custom aggregate target(Eg: Framework)—> 
           Build Phase—> 
               Add Run script

Step 6: Add following shell code in run script

///

UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal

# make sure the output directory exists
mkdir -p "${UNIVERSAL_OUTPUTFOLDER}"

# 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="${BUILD_ROOT}" clean build
xcodebuild -target "${PROJECT_NAME}" -configuration ${CONFIGURATION} -sdk iphonesimulator -arch x86_64 BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build

# Step 2. Copy the framework structure to the universal folder
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework" "${UNIVERSAL_OUTPUTFOLDER}/"

# Step 3. Create universal binary file using lipo and place the combined executable in the copied framework directory
lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework/${PROJECT_NAME}"

Step 7:

Goto active scheme —> 
    Custom aggregate —> 
           Build

Step 8: Now right click framework from products in Xcode & click show in finder.

Check "Debug-universal” folder & get universal framework.
