How to pass data from App to calling function on App close?

I have a function that calls an App made in App Designer. Essentially, the app is a more sophisticated file selection tool than uigetfile(). I would like to have the app pass data back to the calling function when the app is closed. How do I do this?

function s = xyz()
  hApp = selectFiles; % selectFiles is the App
  importInfo(hApp,x,y) % importInfo is a public function of selectFiles and imports data from the calling function to the App
  uiwait(hApp.selectFiles) % pause calling function while App is running
end

On closing selectFiles, I would like to pass data generated in selectFiles to the calling function.

Link to Documentation for sharing data between different apps.

But since in this case your function is making the call to an app, you could dump the value you want to use later into the workspace, and use it later. You could use assignin() to move your data to the workspace .
