Estimated app's store size

Question

After archiving an app version, on the organizer window there was a button, clicking it calculates and displays the estimated size of the app on the store.

In Xcode

Answer 1

If you install on the device, in Settings > General > Storage & iCloud Usage > Manage Storage > [App Name] you can see the size of the app as it's installed on that device.

Not sure how this works with bit code, but at least it's something and easy to do.
