This is fixed in the master branch:

$ cat sr_7011.swift 
import Foundation

let date1 = Date(timeIntervalSince1970: 0)
let date2 = Date()
var difference = Calendar.current.dateComponents([.month, .year, .day], from: date1, to: date2)
print("Difference between", date1, "and", date2, ":")
print("Year:", difference.year!, "Month:", difference.month!, "Day:", difference.day!)

$ ~/swift-DEVELOPMENT-SNAPSHOT-2018-08-15-a-ubuntu16.04/usr/bin/swift sr_7011.swift 
Difference between 1970-01-01 00:00:00 +0000 and 2018-08-16 19:32:41 +0000 :
Year: 48 Month: 7 Day: 15
