How to export “fat” Cocoa Touch Framework (for Simulator and Device both)? , Make framework which works for both simulator and Device

- Make framework which works for both simulator and Device
- How to export “fat” Cocoa Touch Framework (for Simulator and Device both)?
- Undefined symbols for architecture x86_64
- ld: symbol(s) not found for architecture x86_64

Steps 1: First build your frameworks with Simulator target

Steps 2: After success of simulator building process, now build for your framework with device target selection or Generic iOS Device selection

Step 3: Now select your framework target and for that Under "Build Phases" select "Add Run Script" and copy the contents of this file as below: (Note: i have modified slightly in this link script code)

[Note: We must have both compatible framework ready before final step4 (simulator architecture and device architecture compatible, if not please follow above steps correctly)

Step4: Now finally, build again and your framework is ready for both simulator and device compatibility.  Hurrey!!!!

See the reference image:


Put below code into shell area and build again:



# make sure the output directory exists

# 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 ${CONFIGURATION} -sdk iphonesimulator ONLY_ACTIVE_ARCH=NO BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build

# Step 2. Copy the framework structure (from iphoneos build) to the universal folder

# Step 3. Copy Swift modules from iphonesimulator build (if it exists) to the copied framework directory
if [ -d "${SIMULATOR_SWIFT_MODULES_DIR}" ]; then

# Step 4. 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 5. Convenience step to copy the framework to the project's directory

# Step 6. Convenience step to open the project's directory in Finder
open "${BUILD_DIR}/${CONFIGURATION}-universal"

Custom callout : Button is not clickable issue : Quick Fix

Steps To Fix the Issue:

1. Create "MyAnnotationView" custom class extended by "MKAnnotationView" class

2. Add two methods into MyAnnotationView.m class, methods are as below:

- (UIView*)hitTest:(CGPoint)point withEvent:(UIEvent*)event
- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent*)event
