Segmentation fault on a simple swift script

I have a very simple script written in swift and running this with swift file.swift

import Foundation

let url = URL(string: "www.google.com")

and this gives me a segfault error with this message

zsh: segmentation fault  swift file.swift

any ideas as to where the problem is? Thanks!

EDIT: I have tried putting the code to Xcode and it works as it should.

I had a script which was working and suddenly stopped. Exactly on the line where I have created an URL. It was working on Xcode but not from terminal.

Looks like, it is bug.

If you first compile by using swiftc then run it, it is working.

I have found the answer in the following page:
