问题1. 执行xcodebuild报错
xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
解决1. 终端执行如下命令
// Install Xcode
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
问题2. 执行clang -rewrite-objc main.m报错
➜ CopyPropertyForNSStringDemo clang -rewrite-objc main.m

#import <UIKit/UIKit.h>
