具有向后xcode版本兼容性的Swift私有框架

Question

这是我使用Swift语言的第一个框架，它是私有框架。在新的Xcode 9.3发布之前，它的工作正常。升级后更新Xcode会遇到类似Module compiled with Swift 4.0.3 cannot be imported in Swift 4.1的问题。

之后只有我意识到框架不支持自动版本（Xcode / Swift）升级，有些搜索发现有一个Universal or Fat Binary Framework单个版本而不是我之前错过的真实设备和模拟器的单独构建

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

# Make sure the output directory exists

mkdir -p "${UNIVERSAL_OUTPUTFOLDER}"

# Next, work out if we're in SIM or DEVICE

xcodebuild -target "${PROJECT_NAME}" -configuration ${CONFIGURATION} -sdk iphonesimulator ONLY_ACTIVE_ARCH=NO BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build

xcodebuild -target "${PROJECT_NAME}" ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos  BUILD_DIR="${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 (if it exists) to the copied framework directory

BUILD_PRODUCTS="${SYMROOT}/../../../../Products"

cp -R "${BUILD_PRODUCTS}/Debug-iphonesimulator/${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_PRODUCTS}/Debug-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}"

Edit Scheme - ＆gt; Archive - ＆gt; Post-Action - ＆gt; Run Script

这次我使用Swift Compiler - Language - ＆gt; Swift 3.3

我这次也在Xcode 9.3 Swift 4.1

获得预期的输出

当我尝试在Xcode 9.2使用此框架运行项目时，它会显示如下错误 Module compiled with Swift 4.1 cannot be imported in Swift 3.2.3:

尝试以向后兼容性解决，但我没有找到。如何在Xcode 9.2

中运行此框架

框架支持：Swift和Objective C，最低操作系统iOS 8.0

** **更新

也有类似这样的错误 compiled with newer version of Swift language (unknown ABI version 0x06) than previous files (4.0) file 'MAC location' for architecture armv7 并尝试了this to my project
