swift支持OC以及重命名

@objc(PaymentManager)
open class PayManager : NSObject {
    private override init(){}
    @objc(manager)
    public static let manager: PayManager = PayManager()
    @objc
    public func canOpen(_ url: URL) -> Bool{
        return true
    }
}

对于需要支持OC的需要使用@objc标记,同时可以重新定义出在OC中的表现形式,上面的会被编译成如下

SWIFT_CLASS_NAMED("PayManager")
@interface PaymentManager : NSObject
- (nonnull instancetype)init SWIFT_UNAVAILABLE;
+ (nonnull instancetype)new SWIFT_UNAVAILABLE_MSG("-init is unavailable");
SWIFT_CLASS_PROPERTY(@property (nonatomic, class, readonly, strong) PaymentManager * _Nonnull manager;)
+ (PaymentManager * _Nonnull)manager SWIFT_WARN_UNUSED_RESULT;
- (BOOL)canOpen:(NSURL * _Nonnull)url SWIFT_WARN_UNUSED_RESULT;
@end

而在OC中调用即是另一形式，可以充分展现出swift和OC语法的差异化表现形式

 [PaymentManager.manager canOpen:[NSURL URLWithString:@""]];

快速脚本辅助打包

选择我们的framework对应的target,然后新建target

aggregate

新建对应脚本

# Merge Script
 
# 1
# Set bash script to exit immediately if any commands fail.
set -e
 
# 2
# 这里替换成自己的 Framework 名称
FRAMEWORK_NAME="AtomeSDK"
 
# 3
# If remnants from a previous build exist, delete them.
if [ -d "${SRCROOT}/build" ]; then
rm -rf "${SRCROOT}/build"
fi
 
# 4
# Build the framework for device and for simulator (using
# all needed architectures).
xcodebuild -target "${FRAMEWORK_NAME}" -configuration Release -arch arm64 only_active_arch=no defines_module=yes BITCODE_GENERATION_MODE=bitcode OTHER_CFLAGS="-fembed-bitcode" -sdk "iphoneos"
xcodebuild -target "${FRAMEWORK_NAME}" -configuration Release -arch x86_64  only_active_arch=no defines_module=yes BITCODE_GENERATION_MODE=bitcode OTHER_CFLAGS="-fembed-bitcode-marker" -sdk "iphonesimulator"
 
# 5
# Remove .framework file if exists on Desktop from previous run.
if [ -d "${HOME}/Desktop/${FRAMEWORK_NAME}.framework" ]; then
rm -rf "${HOME}/Desktop/${FRAMEWORK_NAME}.framework"
fi
 
# 6
# Copy the device version of framework to Desktop.
cp -r "${SRCROOT}/build/Release-iphoneos/${FRAMEWORK_NAME}.framework" "${HOME}/Desktop/${FRAMEWORK_NAME}.framework"
 
# 7
# Replace the framework executable within the framework with
# a new version created by merging the device and simulator
# frameworks' executables with lipo.
lipo -create -output "${HOME}/Desktop/${FRAMEWORK_NAME}.framework/${FRAMEWORK_NAME}" "${SRCROOT}/build/Release-iphoneos/${FRAMEWORK_NAME}.framework/${FRAMEWORK_NAME}" "${SRCROOT}/build/Release-iphonesimulator/${FRAMEWORK_NAME}.framework/${FRAMEWORK_NAME}"
 
# 8
# Copy the Swift module mappings for the simulator into the
# framework.  The device mappings already exist from step 6.
cp -r "${SRCROOT}/build/Release-iphonesimulator/${FRAMEWORK_NAME}.framework/Modules/${FRAMEWORK_NAME}.swiftmodule/" "${HOME}/Desktop/${FRAMEWORK_NAME}.framework/Modules/${FRAMEWORK_NAME}.swiftmodule"
 
# 9
# Delete the most recent build.
if [ -d "${SRCROOT}/build" ]; then
rm -rf "${SRCROOT}/build"

注意事项

1 开启向后兼容

BUILD_LIBRARIES_FOR_DISTRIBUTION=YES, 代表构建向后兼容的 framework，生成的framework会包含swiftmodule

2 关于使用static/dynamic两种framework

2.1 使用 Dynamic Library

Dynamic Library
此时生成的framework进行分发使用时，宿主项目需要进行特殊设置（为了iOS扩展插件和watch才开放的内嵌形式）

需要选择后两项，否则会报错:image not found

2.2使用 Static Library形式的framework分发

ton

此时生成的framework 拖进项目直接使用即可
