怎样在Swift项目中引入CommonCrypto库

借助modulemap

1.创建modulemap文件

modulemap files

module CCommonCrypto [system] {
    header "/Applications/Xcode.app/Contents/Developer/Platforms/AppleTVOS.platform/Developer/SDKs/AppleTVOS.sdk/usr/include/CommonCrypto/CommonCrypto.h"
    export *
}

module CCommonCrypto [system] {
    header "/Applications/Xcode.app/Contents/Developer/Platforms/AppleTVSimulator.platform/Developer/SDKs/AppleTVSimulator.sdk/usr/include/CommonCrypto/CommonCrypto.h"
    export *
}

module CCommonCrypto [system] {
    header "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/include/CommonCrypto/CommonCrypto.h"
    export *
}

module CCommonCrypto [system] {
    header "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/include/CommonCrypto/CommonCrypto.h"
    export *
}

module CCommonCrypto [system] {
    header "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/CommonCrypto/CommonCrypto.h"
    export *
}

module CCommonCrypto [system] {
    header "/Applications/Xcode.app/Contents/Developer/Platforms/WatchOS.platform/Developer/SDKs/WatchOS.sdk/usr/include/CommonCrypto/CommonCrypto.h"
    export *
}

module CCommonCrypto [system] {
    header "/Applications/Xcode.app/Contents/Developer/Platforms/WatchSimulator.platform/Developer/SDKs/WatchSimulator.sdk/usr/include/CommonCrypto/CommonCrypto.h"
    export *
}

2.将modulemap路径添加到Import Paths

Import Paths

3.导入头文件使用

tips:如何在pod中使用？

在podspec中添加s.preserve_paths、s.pod_target_xcconfig

s.preserve_paths = 'CocoaPods/**/*'
s.pod_target_xcconfig = {
    'SWIFT_INCLUDE_PATHS[sdk=macosx*]'           => '$(PODS_ROOT)/JRString/CocoaPods/macosx',
    'SWIFT_INCLUDE_PATHS[sdk=iphoneos*]'         => '$(PODS_ROOT)/JRString/CocoaPods/iphoneos',
    'SWIFT_INCLUDE_PATHS[sdk=iphonesimulator*]'  => '$(PODS_ROOT)/JRString/CocoaPods/iphonesimulator',
    'SWIFT_INCLUDE_PATHS[sdk=appletvos*]'        => '$(PODS_ROOT)/JRString/CocoaPods/appletvos',
    'SWIFT_INCLUDE_PATHS[sdk=appletvsimulator*]' => '$(PODS_ROOT)/JRString/CocoaPods/appletvsimulator',
    'SWIFT_INCLUDE_PATHS[sdk=watchos*]'          => '$(PODS_ROOT)/JRString/CocoaPods/watchos',
    'SWIFT_INCLUDE_PATHS[sdk=watchsimulator*]'   => '$(PODS_ROOT)/JRString/CocoaPods/watchsimulator'
}

注意：pod lib lint 校验不会通过，提交时可跳过此步直接push
