Create a partial Native-Ionic app

I have a client that wants half of an app to be created in native Objective-C (my specialty) and have another developer work in Ionic for a single screen in the app.

Is it possible to import specific folders/directories from his Ionic project directly to my app, such as from a Git repo, and have everything compile?

If not, can I manually copy specific folders and files with a few minor code changes to make it work?

Is the process more involved than that? do I need Ionic installed on my machine to perform local builds or are there other limitations?

Thanks in advance for any help.

For that, you wouldn’t need to install the ionic cli

Once you have the cordova webview setup, you would manually setup a project a project.
