Hi guys, i am trying to debug swift-corelibs-foundatin with lldb in Linux. However, it keeps giving me "" when I try to access a variable. Here is my testing example:

import Foundation
let c1 = NSDateComponents()
let c2 = NSDateComponents()
c2.calendar = c1.calendar
let c1a = c1.calendar as Any
print(c1a)
let c2a = c2.calendar as Any
print(c2a)

I have set breakpoint at c2.calendar = c1.calendar. When i step in, it reaches NSCalendar.swift under Foundation as follows:

(lldb) s
Process 9448 stopped
* thread #1, name = 'simCalendarCopy', stop reason = step in
    frame #0: 0x000003fffd6eff9e libFoundation.so`NSDateComponents.calendar.setter(newValue=<unavailable>, self=<unavailable>) at NSCalendar.swift:1428
   1425             return _calendar
   1426         }
   1427         set {
-> 1428             if let val = newValue {
   1429                 _calendar = val
   1430             } else {
   1431                 _calendar = nil
Target 0: (simCalendarCopy) stopped.

Then when i tried to fr v val, the debugger would show me could not resolve type. It looks like lldb won't print any variables when it gets into the Foundation code. Any ideas how to fix this?

It looks like the foundation module isn't imported. Can you file a SR?

Thanks, I'll try to take a look as time permits.
