    let's re-open something. The question is quite a matter of itself - swift has some oddities with syntax enforcing. I think this question may come in handy. - Max Mikheyenko
  • @MaxMikheyenko, you must first bring the question to a normal form. Now the question, in my opinion, is useless for those who are faced with a similar problem: because they simply will not find it by search engines. that's why I voted for the closure. - aleksandr barakin
  • @alexanderbarakin tried to fix - Max Mikheyenko

there is either no space

 for i in 0..<numberOfEuropeCities {

either be on both sides

 for i in 0 ..< numberOfEuropeCities {

    Problem solved!
    My error disappeared when I added a space:

     for i in 0 ..< numberOfEuropeCities
