I might be wrong but you are missing one parameter in your predicate you are passing in nil so there is nothing to sort essentially no output. Try changing your code to:

 let sources = eventStore.sources
    for source in sources{
        print(source.title)
        for calendar in source.calendars(for: .event){
            print(calendar.title)
        }
    }

    let calendars = eventStore.calendars(for: .event)
    let predicate = self.eventStore.predicateForEvents(withStart: startDate, end: endDate, calendars: calendars)  //change here
    let events = self.eventStore.events(matching: predicate)
    print(calendars)
    print(events)
