Extra-Terrestrial Challenge Swift

Question

https://code.sololearn.com/cdcNRy953WX5/?ref=app

Attached is my Swift code for the challenge. The code works but due to Swift lacking an input() function, the app cannot run the code according to its tests. Does anyone have a solution? (P.S. readLine() does not work)
Thank you!
