Re: [swift-corelibs-dev] Fatal error Foundation/NSCalendar.swift, Ubuntu 16.04, Swift 3.0.1

Hi Malcolm,

Looks like it. If you go ahead and file a JIRA at bugs.swift.org 
, hopefully someone can take a look.

Thanks,

Re: [swift-corelibs-dev] Fatal error Foundation/NSCalendar.swift, Ubuntu 16.04, Swift 3.0.1

Hello Malcolm,

It looks like cutting line 606 of NSCalendar.swift and pasting it over `false` 
on line 607 fixes the issue.

  1> import Foundation 
  2. let fromDate = Date() 
  3. let toDate = Date(timeIntervalSinceNow: 20) 
  4. let components = Calendar.current.dateComponents([.second], from: 
fromDate, to: toDate)
// ...
[6] = 20
// ...

Regards,
Will Stanton

Hi Will,

Fair enough, I know very little about the inner workings of the Foundation 
libraries ¯\_(ツ)_/¯ Hoping someone can raise a sensible PR that fixes the issue.

Best regards,
Malcolm
