做React-Native项目时，使用Realm做数据持久化，由于种种不便，所以将其删除。
由于项目依赖关系，故使用以下命令：
1.删除项目依赖
$ npm uninstall realm --save
到此处，不能高兴太早，被坑的很惨啊！！！！
2.编译iOS，运行为啥报错呢？？
报错信息如下：
Failed to install the requested application
An application bundle was not found at the provided path.
Provide a valid path to the desired application bundle.
Print: Entry, ":CFBundleIdentifier", Does Not Exist
Command failed: /usr/libexec/PlistBuddy -c Print:CFBundleIdentifier build/Build/Products/Debug-iphonesimulator/ReactNativexx.app/Info.plist
Print: Entry, ":CFBundleIdentifier", Does Not Exist
看到这些，蛋都碎了，有木有？？有木有？？明明什么么都没做，为啥运行出错呢？？
3.在xcode中删除相关配置
删除库文件01.png
删除库文件02.png
删除库文件03.png
至此xcode中编译成功
