tns update deletes the hooks folder

Hi,

I would like to create an iOS application which before preparing the project runs a little script which updates the Info.plist files with the appropriate version number.

It works perfectly, but when I run tns update than my hooks folder just deleted and adds only the 'nativescript-dev-typescript.js' files into it, so it removes my before-prepare script.

首先，使用一个在 hooks 文件夹中包含自定义 before-prepare 脚本的 iOS 应用重现该问题，然后运行 tns update。跟踪 tns update 如何重新构建或替换 hooks 文件夹；完成的标准是自定义脚本仍然保留，同时 nativescript-dev-typescript.js 文件仍会被添加。
