ios - AVCaptureDevice.requestAccess() crash -

-

i created ios single view application using swift 3.0 , xcode 8 beta 2. linking avfoundation.framework.

this view controller code:

import uikit import avfoundation  class viewcontroller: uiviewcontroller {    override func viewdidload() {     super.viewdidload()      if avcapturedevice.authorizationstatus(formediatype: avmediatypevideo) == .notdetermined {       avcapturedevice.requestaccess(formediatype: avmediatypevideo, completionhandler: { (granted: bool) in         if granted {           print("granted")         }         else {           print("not granted")         }       })     }   } }

when run on device app crashes after executing avcapture.requestaccess line (the completion handler not executed , no exceptions thrown).

the thing in console is:

2016-07-15 14:55:44.621819 testpp[2261:912051] [mc] system group container systemgroup.com.apple.configurationprofiles path /private/var/containers/shared/systemgroup/systemgroup.com.apple.configurationprofiles 2016-07-15 14:55:44.626012 testpp[2261:912051] [mc] reading public effective user settings. 2016-07-15 14:55:59.284610 testpp[2261:912085] [access] <private>

am doing wrong?

make sure set value privacy - camera usage description key in info.plist file when requesting camera access.
