xcode升级到10后，运行报下面错误，大概意思就是，你的某个sdk/项目里面有多余的info.plist文件
:-1: Multiple commands produce '/Users/zhangxiangdong/Library/Developer/Xcode/DerivedData/XCLSDKDemo-dwzoiktyggcxpifyjnpgrdoafkgl/Build/Products/Debug-iphoneos/KooliveUKitSDK.framework/Info.plist':
1) Target 'KooliveUKitSDK' (project 'KooliveUKitSDK') has copy command from '/Users/zhangxiangdong/Desktop/Kool-XCLSDK/KooliveUKitSDK/KooliveUKitSDK/Info.plist' to '/Users/zhangxiangdong/Library/Developer/Xcode/DerivedData/XCLSDKDemo-dwzoiktyggcxpifyjnpgrdoafkgl/Build/Products/Debug-iphoneos/KooliveUKitSDK.framework/Info.plist'
2) Target 'KooliveUKitSDK' (project 'KooliveUKitSDK') has process command with output '/Users/zhangxiangdong/Library/Developer/Xcode/DerivedData/XCLSDKDemo-dwzoiktyggcxpifyjnpgrdoafkgl/Build/Products/Debug-iphoneos/KooliveUKitSDK.framework/Info.plist'
具体修改办法：删除下图中的info.plist文件即可
