Swift制作打包framework

新建framework项目

设置生成fat包，包括模拟器x86_64和arm64

Buliding Settings -> Architectures -> Build Active Architecture Only 设置为NO

设置打包环境，选择release

edit Scheme -> run -> Build configuration 设置为 Release

设置静态库

 Buliding Settings -> Linking -> Dead Code Stripping 设置为NO

 Buliding Settings -> Linking -> Mach-O Type 设置为Static Library

创建打包合并framework脚本

添加打包+合成脚本代码：

# Install dir will be the final output to the framework.
# The following line create it in the root folder of the current project.
FMK_NAME=${PROJECT_NAME}
INSTALL_DIR=${SRCROOT}/Products/${FMK_NAME}.framework
 
# Working dir will be deleted after the framework creation.
WRK_DIR=build
DEVICE_DIR=${WRK_DIR}/Build/Products/Release-iphoneos/${FMK_NAME}.framework
SIMULATOR_DIR=${WRK_DIR}/Build/Products/Release-iphonesimulator/${FMK_NAME}.framework
 
# -configuration ${CONFIGURATION}
# Clean and Building both architectures.
xcodebuild -project ${FMK_NAME}.xcodeproj -scheme ${FMK_NAME}  -configuration Release -derivedDataPath ${WRK_DIR} clean
 
xcodebuild -project ${FMK_NAME}.xcodeproj -scheme ${FMK_NAME} -configuration Release -derivedDataPath ${WRK_DIR} -sdk iphoneos -arch arm64  clean build
# simulator
xcodebuild -project ${FMK_NAME}.xcodeproj -scheme ${FMK_NAME} -configuration Release -derivedDataPath ${WRK_DIR} -sdk iphonesimulator -arch x86_64 build
 
# Cleaning the oldest.
if [ -d "${INSTALL_DIR}" ]
then
rm -rf "${INSTALL_DIR}"
fi
 
 
mkdir -p "${INSTALL_DIR}"
 
cp -R "${DEVICE_DIR}/" "${INSTALL_DIR}/"
 
# Uses the Lipo Tool to merge both binary files (i386 + armv6/armv7) into one Universal final product.
lipo -create "${DEVICE_DIR}/${FMK_NAME}" "${SIMULATOR_DIR}/${FMK_NAME}" -output "${INSTALL_DIR}/${FMK_NAME}"
 
cp -R "${SIMULATOR_DIR}/Modules/${FMK_NAME}.swiftmodule" "${INSTALL_DIR}/Modules/"
 
#rm -r "${WRK_DIR}"
 
open "${SRCROOT}/Products/"

运行脚本，生成的framework会在项目根目录的Products文件夹下。

添加swift类到工程

TestTool.swift

import UIKit
 
// 可以在模块外被调用
public class TestTool: NSObject {
 
    
    // 只能在模块中被调用
    func HelloWorld(withParam param: String) -> Void {
        print(param)
    }
    
    // 可以在模块外被调用，只能在swift中被调用
    public func publicSayHelloWorld() {
        print("sayHelloWorld")
    }
    
    open func openSayHelloWorld() {
        print("sayHelloWorld")
    }
    
    // @objc public 同时修饰，才能在OC项目中被调用；并且也能被swift项目调用
    @objc public func sayHelloWorldToOC() {
        print("sayHelloWorldToOC")
    }
}

注意添加public修饰符到class，将类暴露出来

右键生成的framework，选择显示包内容，打开Headers目录下的XXXX-Swift.h，能找到刚刚添加的TestTool。

SWIFT_CLASS("_TtC7TestSDK8TestTool")
@interface TestTool : NSObject
- (void)sayHelloWorldToOC;
- (nonnull instancetype)init OBJC_DESIGNATED_INITIALIZER;
@end
