I want to create a private cocoapod of the output framework built for both simulators and devices.
I have created a Cocoa touch framework in which I have integrated CocoaLumberjack using Cocoapods. I want to build the framework for all architectures possible (simulator as well as device).
By default the build setting,
'Build Active Architectures Only' is set to (Debug - Yes, Release - No).
As soon as I set this setting for debug to No, the build fails with the following linker error:
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_DDASLLogger", referenced from:
objc-class-ref in MyManager.o
"_OBJC_CLASS_$_DDLog", referenced from:
objc-class-ref in MyManager.o
"_OBJC_CLASS_$_DDTTYLogger", referenced from:
objc-class-ref in MyManager.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I get it that CocoaLumberjack is available for only active architectures in debug version.
So I switch back the Build active architectures for debug to Yes and build the framework successfully.
To build the framework for all the architectures I am using a run script added in Build phases that also claims to merge the ios-device and ios-simulator build into one. Here is the script:
set -e
set +u
# Avoid recursively calling this script.
if [[ $SF_MASTER_SCRIPT_RUNNING ]]
then
exit 0
fi
set -u
export SF_MASTER_SCRIPT_RUNNING=1
# Constants
SF_TARGET_NAME=${PROJECT_NAME}
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal
# Take build target
if [[ "$SDK_NAME" =~ ([A-Za-z]+) ]]
then
SF_SDK_PLATFORM=${BASH_REMATCH[1]}
else
echo "Could not find platform name from SDK_NAME: $SDK_NAME"
exit 1
fi
if [[ "$SF_SDK_PLATFORM" = "iphoneos" ]]
then
echo "Please choose iPhone simulator as the build target."
exit 1
fi
IPHONE_DEVICE_BUILD_DIR=${BUILD_DIR}/${CONFIGURATION}-iphoneos
# Build the other (non-simulator) platform
xcodebuild -project "${PROJECT_FILE_PATH}" -target "${TARGET_NAME}" -configuration "${CONFIGURATION}" -sdk iphoneos BUILD_DIR="${BUILD_DIR}" OBJROOT="${OBJROOT}" BUILD_ROOT="${BUILD_ROOT}" CONFIGURATION_BUILD_DIR="${IPHONE_DEVICE_BUILD_DIR}/arm64" SYMROOT="${SYMROOT}" ARCHS='arm64' VALID_ARCHS='arm64' $ACTION
xcodebuild -project "${PROJECT_FILE_PATH}" -target "${TARGET_NAME}" -configuration "${CONFIGURATION}" -sdk iphoneos BUILD_DIR="${BUILD_DIR}" OBJROOT="${OBJROOT}" BUILD_ROOT="${BUILD_ROOT}" CONFIGURATION_BUILD_DIR="${IPHONE_DEVICE_BUILD_DIR}/armv7" SYMROOT="${SYMROOT}" ARCHS='armv7 armv7s' VALID_ARCHS='armv7 armv7s' $ACTION
# Copy the framework structure to the universal folder (clean it first)
rm -rf "${UNIVERSAL_OUTPUTFOLDER}"
mkdir -p "${UNIVERSAL_OUTPUTFOLDER}"
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework" "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework"
# Smash them together to combine all architectures
lipo -create "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/arm64/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/armv7/${PROJECT_NAME}.framework/${PROJECT_NAME}" -output "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/${PROJECT_NAME}"
I check the 'Run script only when installing' checkbox present below the run script. Now I build the framework for Generic iOS device. Now i click on the Products group present in the Project hierarchy and select the MyFramework.framework file, right click and select show in finder. It opens up the ~/Library/Developer/Xcode/DerivedData/MyFramework-dlpsipmxkqmemwgqrfeovlzgyhca/Build/Products/Debug-iphoneos/MyFramework.framework in finder.
Now, I create a new tag 'MyFramework-v0.0.1' containing the commit where I added MyFramework.framework file.
I go to ~/.cocoapods/repos/MyRepoName/ and create a podspec file MyFramework.podspec as follows:
Pod::Spec.new do |s|
s.name = "MyFramework"
s.version = "0.0.1"
s.summary = "A pod for MyFramework"
s.description = "A pod designed for MyFramework"
s.homepage = "My_Private_Repo_Path"
s.license = { :type => "MIT", :file => "FILE_LICENSE" }
s.authors = { "My_Username" => "my_email_address"
}
s.platform = :ios, "8.0"
s.ios.deployment_target = "8.0"
s.source = { :git => "My_Private_Repo_Path", :tag => 'MyFramework-v'+String(s.version) }
s.requires_arc = true
s.vendored_frameworks = "MyFramework.framework"
s.dependency "CocoaLumberjack"
end
Now when I run the following command in the terminal:
pod repo push MyRepoName MyFramework.podspec
I get the following Error:
Validating spec
-> MyFramework (0.0.1)
- ERROR | [iOS] xcodebuild: Returned an unsuccessful exit code. You can use ` --verbose` for more information.

How to build cocoa touch framework for all devices and simulators, that is dependent on another framework (CocoaLumberjack) added using cocoapods? I need to create a private pod of the output framework.
