I need to build my existing XCFramework for supporting the new Apple Silicon arm64 simulator..
When I archive using the following xcodebuild command:
if [ "${CONFIGURATION}" = "Release" ]; then
xcodebuild archive \
-scheme ${PROJECT_NAME}_MFI \
-archivePath "build/${PROJECT_NAME}_arm64simulator.xcarchive" \
-sdk iphonesimulator-arm64 \
-UseModernBuildSystem=YES
fi
Xcode would complain by:
xcodebuild: error: SDK "iphonesimulator-arm64" cannot be located.
I have also tried
-sdk ios-arm64-simulator
I am using Xcode Version 12.3 (12C33).
Try to separate your parameter to this:
-arch arm64
-sdk iphonesimulator
Im trying to create an universal framework from one of the targets in my project. I have used a few scripts, I have found on the internet, but I have one problem - the final framework, doesn't seem to include bitcode. This is the script, that I'm using to create this framework:
UNIVERSAL_OUTPUT_DIR=${BUILD_DIR}/${CONFIGURATION}-universal
RELEASE_DIR=${PROJECT_DIR}/build
TARGET="Observation"
mkdir -p "${UNIVERSAL_OUTPUT_DIR}"
xcodebuild BITCODE_GENERATION_MODE=bitcode -target "${TARGET}" ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build -sdk iphoneos
xcodebuild BITCODE_GENERATION_MODE=bitcode -target "${TARGET}" ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build -sdk iphonesimulator
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${TARGET}.framework" "${UNIVERSAL_OUTPUT_DIR}/"
SIMULATOR_SWIFT_MODULES_DIR="${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${TARGET}.framework/Modules/${TARGET}.swiftmodule/."
if [ -d "${SIMULATOR_SWIFT_MODULES_DIR}" ]; then
cp -R "${SIMULATOR_SWIFT_MODULES_DIR}" "${UNIVERSAL_OUTPUT_DIR}/${TARGET}.framework/Modules/${TARGET}.swiftmodule"
fi
lipo -create -output "${UNIVERSAL_OUTPUT_DIR}/${TARGET}.framework/${TARGET}" "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${TARGET}.framework/${TARGET}" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${TARGET}.framework/${TARGET}"
cp -R "${UNIVERSAL_OUTPUT_DIR}/${TARGET}.framework" "${RELEASE_DIR}"
open "${RELEASE_DIR}"
And when I try to use it, I get this error:
ld: '/Users/homedudycz/Desktop/Test/Test/Observation.framework/Observation' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. file '/Users/homedudycz/Desktop/Test/Test/Observation.framework/Observation' for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Can someone help me with this?
Have setup a sample on Github, I'm using Xcode v 9.4.1

Basically I'm trying to build my framework to include bitcode in the x86_64 simulator build. I tried various settings and tried building on command line, xcodebuild refuses to include bitcode in my simulator build, however it is very happy to include it in the arm64 (device) build.
All the following commands should be able to run from the same folder the above framework is checked out.
Following are the commands I've tried to build the above framework:
xcodebuild ENABLE_BITCODE[sdk=iphone*]=YES BITCODE_GENERATION_MODE=bitcode DYLIB_COMPATIBILITY_VERSION=1 -sdk iphonesimulator -configuration Release -target TreeFramework clean build
xcodebuild OTHER_CFLAGS="-fembed-bitcode" ENABLE_BITCODE[sdk=iphone*]=YES BITCODE_GENERATION_MODE=bitcode -sdk iphonesimulator -configuration Release -target TreeFramework clean build
xcodebuild OTHER_CFLAGS="-fembed-bitcode" ENABLE_BITCODE="YES" BITCODE_GENERATION_MODE="bitcode" -sdk iphonesimulator -configuration Release -target TreeFramework clean build
Ran the following to verify bitcode is emitted (it doesn't in this case).
otool -arch x86_64 -l build/Release-iphonesimulator/TreeFramework.framework/TreeFramework | grep LLVM
However when I build for a device, bitcode is included.
xcodebuild -sdk iphoneos -configuration Release -target TreeFramework clean build
Verify bitcode is emitted:
otool -arch arm64 -l build/Release-iphoneos/TreeFramework.framework/TreeFramework | grep LLVM
Appreciate any help.

Hi, I am trying to create a framework to support armv7, armv7s, arm64, i386 and x86_64. I am using aggregate to make the fat library. Inside the aggregate script, i am running two xcodebuild commands 1. for armv7, armv7s and arm64 and 2. for i386 and x86_64 architectures. Also, I have set Enable Bitcode=YES and Other C Flags=-fembed-bitcode under target build settings. As a precautionary mesasure, i am adding ENABLE_BITCODE=YES and OTHER_CFLAGS="-fembed-bitcode" options to the xcodebuild command
My xcode build commands are as follows -
#Build The framework Target for iPhoneOS
xcodebuild -project "${PROJECT_FILE_PATH}" -target "${AN_TARGET}"
ONLY_ACTIVE_ARCH=NO -configuration "${CONFIGURATION}" -sdk iphoneos
BUILD_DIR="${BUILD_DIR}" OBJROOT="${OBJROOT}" BUILD_ROOT="${BUILD_ROOT}"
CONFIGURATION_BUILD_DIR="${IPHONE_DEVICE_BUILD_DIR}" SYMROOT="${SYMROOT}"
ARCHS="armv7 armv7s arm64" ENABLE_BITCODE=YES OTHER_CFLAGS="-fembed-bitcode" $ACTION
#Build The framework Target for iPhoneSimulator
xcodebuild -project "${PROJECT_FILE_PATH}" -target "${AN_TARGET}"
ONLY_ACTIVE_ARCH=NO -configuration "${CONFIGURATION}" -sdk iphonesimulator
BUILD_DIR="${BUILD_DIR}" OBJROOT="${OBJROOT}" BUILD_ROOT="${BUILD_ROOT}"
CONFIGURATION_BUILD_DIR="${IPHONE_SIMULATOR_BUILD_DIR}" SYMROOT="${SYMROOT}"
ARCHS="i386 x86_64" ENABLE_BITCODE=YES OTHER_CFLAGS="-fembed-bitcode" $ACTION
after running the above two commands, i am combining these two builds to make a fat framework binary using the below command
# create a fat Framework
lipo -create
"${IPHONE_DEVICE_BUILD_DIR}/${PROJECT_NAME}.framework/${PROJECT_NAME}"
"${IPHONE_SIMULATOR_BUILD_DIR}/${PROJECT_NAME}.framework/${PROJECT_NAME}" -
output "${FRAMEWORK_FOLDER}/${AN_END_USER_FRAMEWORK_NAME}"
The issue iam facing is after the lipo is created, i am unable to use it in the bitcode enabled application. After running the otool -l framework_binary | grep -LLVM, i do not see the bitcode enabled flags or __LLVM.
Lipo removes bitcode from the fat binary. Is there a way i can retain bitcode while running the lipo command?
Correction: Based on the reply from Nestor, i ran the otool command as otool -l -arch armv7 framework_binary | grep LLVM and much to my surprise, i could see the segname __LLVM clang. However when i integrate the same fat framework binary into my project, it builds fine on simulator however throws the following error while running on device - ld: 'MyBinary' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture armv7
Happily it's just a problem with otool's reporting, not lipo; you have to add the -arch parameter:
otool -arch arm64 -l myLipoOutput.a
Source: http://www.openradar.me/radar?id=6301306440384512
This is something weird, there are not many documentation for do this, at the end I use this command:
xcodebuild -project ${PROJECT_NAME}.xcodeproj -target ${FRAMEWORK_NAME} ONLY_ACTIVE_ARCH=NO BITCODE_GENERATION_MODE=bitcode FRAMEWORK_SEARCH_PATHS="${FRAMEWORK_SEARCH_PARTH} ${SRCROOT}/**" -sdk ${SIMULATOR_SDK} -configuration ${CONFIGURATION} clean build CONFIGURATION_BUILD_DIR=${BUILD_DIR}/${CONFIGURATION}-${SIMULATOR_SDK} 2>&1
xcodebuild -project ${PROJECT_NAME}.xcodeproj -target ${FRAMEWORK_NAME} -sdk ${DEVICE_SDK} ONLY_ACTIVE_ARCH=NO BITCODE_GENERATION_MODE=bitcode FRAMEWORK_SEARCH_PATHS="${FRAMEWORK_SEARCH_PARTH} ${SRCROOT}/**" -configuration ${CONFIGURATION} clean build CONFIGURATION_BUILD_DIR=${BUILD_DIR}/${CONFIGURATION}-${DEVICE_SDK} 2>&1
Add the BITCODE_GENERATION_MODE=bitcode flag to the xcodebuild command
Try to use archive for the arm slices instead of build
xcodebuild -scheme "${SCHEME}" -workspace "${WORKSPACE}" -configuration "${CONFIGURATION}" -sdk iphoneos ARCHS="arm64 armv7 armv7s" CONFIGURATION_BUILD_DIR="${CONFIGURATION_BUILD_DIR}/arm" CODE_SIGN_IDENTITY="" CODE_SIGNING_REQUIRED=NO ONLY_ACTIVE_ARCH=NO archive
After that run lipo to merge the simulator and the arm ones.
And after that run otool -arch arm64 -l myLipoOutput.a and it should work.
It looks like a bug in Xcode 7.0.1 . I've had the same issue and downgrading Xcode to version 7 fixed it.
Update:
Actually it may be a bug in Xcode 7 that was fixed in 7.0.1 - this SO answer solved the issue for me.
I'm trying to build a framework that will work with iphonesimulator on both 64-32x.
The command i'm executing is:
xcodebuild -target mypack -sdk iphonesimulator8.1 -configuration Release -arch i386
For some reason it's threw me an error when i'm trying to run this framework on a 64x project ipa using iphonesimulator.
can someone tell me what i'm doing wrong?
I added a new arch called x86_64 into my framework project and then what fix for me the problem is the following command:
xcodebuild -target MobileCore -sdk iphonesimulator8.1 -configuration Release -arch i386 -arch x86_64
