How to build Cocoa Touch Framework for i386 and x86_64 architecture?(如何为 i386 和 x86_64 架构构建 Cocoa Touch 框架?)
问题描述
在构建 Cocoa Touch 框架(Swift 或 Object-C)并将其作为嵌入式二进制文件"添加到另一个项目后，当我尝试构建时收到以下错误消息
6) 点击 "cmd + B"(构建项目)
7) 在Finder中打开产品
8)向上导航1个目录(cmd + ↑")，您将看到Release-universal"目录.
会有你的 "fat/universal" 库，你准备好了！
您可以通过以下方式查看
After building a Cocoa Touch framework (Swift or Object-C) and adding it to another project as "Embedded Binaries" I get the following error message when I try to build
Following various existing answers and extended research I already added i386 to the Architectures build settings …
However this doesn't seem to have an effect. When I check using
I only get
… shouldn't i386 (and x86_64) appear here as well? What am I missing?
(I am using Xcode 6.2 + building for iOS 8.2)
Some new insights
Using a version of this build script I am able to build the missing architectures for the Swift version of the framework.
However when I add this framework to my app and build I still get errors
Looking at the final build folder building for the simulator
I can see that the architectures are still missing although they were part of the framework (as shown). How can I ensure all the right architecture builds of my framework are included when building the app?
Update
Looking at all the error messages to me it looks like the issue isn't actually to have the wrong products/archictures being built but one step later there the Linker isn't using the correct paths to them. Not sure how correct this.
This is the same problem that I had.
Seems this is a Xcode bug, I workaround it by adding a build script.
It will just compile your library with all architectures, and lipo it to fat binary image.
Also note
Looking at the final build folder building for the simulator
Build/Products/Debug-iphoneos/TesterFrameworkSwift.framework/
you are looking x86_64 and i386 images in iphone build folder, they should be in Debug-iphonesimulator/TesterFrameworkSwift.framework/
Also there is a recursion issue in your script, I've corrected it.
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal
if [ "true" == ${ALREADYINVOKED:-false} ]
then
echo "RECURSION: Detected, stopping"
else
export ALREADYINVOKED="true"
# Step 1. Build Device and Simulator versions
xcodebuild -target "${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="${BUILD_ROOT}" clean build
# Step 2. Copy the framework structure (from iphoneos build) to the universal folder
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework" "${UNIVERSAL_OUTPUTFOLDER}/"
# Step 3. Copy Swift modules (from iphonesimulator build) to the copied framework directory
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule/." "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule"
# 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/${PROJECT_NAME}"
# Step 5. Convenience step to copy the framework to the project's directory
cp -R "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework" "${PROJECT_DIR}"
# Step 6. Convenience step to open the project's directory in Finder
open "${PROJECT_DIR}"
fi
6) Hit "cmd + B" (Build Project)
7) Open Product in Finder
8) Navigate 1 directory up ("cmd + ↑"), and you will see "Release-universal" directory.
There will be your "fat/universal" library, You are ready to go!
