xcode continues project loading forever

Question

I have a source code of a swift application which developed for iOS using swift 3.

I want to run it inside Xcode however it remains in loading state forever. I have tried solutions provided in question Xcode freezes on startup while loading project however the situation did not change.

The developer of this source code told me that he used Xcode 9.x to develop application so he suggested me to try a 9.x version of Xcode. I guess Xcode should be backward compatible however I want to know does using Xcode 9.x changes the situation or I should look for reason somewhere else?

Using answer in apple.stackexchange.com did the trick:

Removing the ~/Library/Saved Application State/com.apple.dt.Xcode.savedState/directory might help.
