在 objc 项目 xcode 11.3.1 中导入 swift 框架？

Question

I have question about framework.
When I import my customized swift framework in Objc project, I cant init class object and find customized delegate.
And I also have script to combined different framework like this:
Is my script problem?
Or project setting problem?

Xcode 11.3.1
swift 5

#!/bin/sh
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal
# make sure the output directory exists
mkdir -p "${UNIVERSAL_OUTPUTFOLDER}"
# Step 1. Build Device and Simulator versions
xcodebuild -target "XXXSDK" ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos  BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
xcodebuild -target "XXXSDK" -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}/${CONFIGURATION}-iphoneos/XXXSDK.framework" "${UNIVERSAL_OUTPUTFOLDER}/"
# Step 3. Copy Swift modules from iphonesimulator build (if it exists) to the copied framework directory
SIMULATOR_SWIFT_MODULES_DIR="${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/XXXSDK.framework/Modules/XXXSDK.swiftmodule/."
if [ -d "${SIMULATOR_SWIFT_MODULES_DIR}" ]; then
cp -R "${SIMULATOR_SWIFT_MODULES_DIR}" "${UNIVERSAL_OUTPUTFOLDER}/XXXSDK.framework/Modules/XXXSDK.swiftmodule"
fi
# Step 4. Create universal binary file using lipo and place the combined executable in the copied framework directory
lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/XXXSDK.framework/XXXSDK" "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/XXXSDK.framework/XXXSDK" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/XXXSDK.framework/XXXSDK"
# Step 5. Convenience step to copy the framework to the project's directory
cp -R "${UNIVERSAL_OUTPUTFOLDER}/XXXSDK.framework" "${PROJECT_DIR}"
cp -R "${UNIVERSAL_OUTPUTFOLDER}/XXXSDK.framework" "${PROJECT_DIR}/../../XXXSDKDemo"
cp -R "${UNIVERSAL_OUTPUTFOLDER}/XXXSDK.framework" "${PROJECT_DIR}/../../XXXSDKObjcDemo"
# Step 6. Convenience step to open the project's directory in Finder
open "${PROJECT_DIR}"

If you build your framework with xcframeworks, all this configuration mess will be a lot easier. If you can, give it a try. Look at https://github.com/bielikb/xcframeworks

There should not be any problem to consume swift framework in objective c, check if the framework has the correct .h file in it.

If you want to combine multiple framework in one the you can use lipo command from terminal. Please do check the combined framework after lipo and see if there is the header file.

Also try to use the frameworks individually before lipo.
