ios - UIContainerView with intrinsic size placeholder values for AutoLayout doesn't receive events? -


this xcode 7.0 beta 6 (7a192o). seems specifying intrinsic size placeholder values uicontainerview causes not receive events.

  1. create standard single view application.
  2. in view, insert uicontainerview (center auto layout)
  3. embed simple button uicontainerview.
  4. run simulator , observe if click on button can see responds (dims)
  5. stop the simulator , add intrinsic size placeholders uicontainerview.
  6. run simulator , observe if click on button no longer see responds (dims).
  7. stop simulator , either remove intrinsic size placeholders or set them none.
  8. run simulator , observe if click on button can see responds again.

no warnings/errors appear in log.

i've uploaded video of behavior here. doing wrong or bug? i'm rather new auto-layouts want check if doing wrongly before filing bug apple.
