Trying to read an Objective-C NSDictionary from Swift results on a Data array

Hi I am trying to get a read a property(NSDictionary) of an objective-c class from a swift class. When I debug the code at the point where the dictionary is passed it has the data I'm expecting, but when the swift code comes into place all I'm getting is this:

{
  [0] = {
    key = 0x00007ffae0f8bf10
    value = 0x00007ffae0f8bf30
  }
  [1] = {
    key = 0x00007ffae0f8ba10
    value = 0x00007ffae0f8ae40
  }
  [2] = {
    key = 0x00007ffae0f8bf50
    value = 0x0000000105277ce0
  }
  [3] = {
    key = 0x00007ffae0f8b1e0
    value = 0x0000000105277ce0
  }
  [4] = {
    key = 0x00007ffae0f8b160
    value = 0x0000000105278420
  }...
