Swift iOS -UIImagePicker's Photo Library Is Presented On Simulator But Crashes (won't present) On Actual Device While Running Xcode -

i'm on swift 3, ios 10.3, , xcode 8.3.3.

when access photo library on simulator uiimagepicker presented no problem , can pick photos. as try access photo library on actual device (iphone 7+) app crashes because uiimagepicker won't presented (i don't point pick photo). odd thing on actual device imagepicker presents camera , can take photos no problem.

even though didn't add inside question, inside actual code have api permissions running. inside actual code used them , commented them out , problem still occurs:

import avfoundation  //there way more code put these here show i'm using them phphotolibrary.authorizationstatus() phphotolibrary.requestauthorization() avcapturedevice.authorizationstatus(formediatype: ...) avcapturedevice.requestaccess(formediatype: ...) 

update: still haven't resolved issue have found out more information. kept playing around app , tried app again after crash , let me access library. came realize app let me access library on phone long xcode isn't running. plug phone xcode , try access library again crash. don't know make of that.

as long xcode isn't hooked device can obtain photos libary. simulator have no problems obtaining photos. device not hooked xcode can obtain photos. once device , xcode connected crash. i've tried initializing uiimagepicker 3 different ways (as stated below) see if either of them change outcome it's same. app on 100 classes , 50 vcs, maybe problem happening somewhere else. if happening somewhere else should crash when xcode isn't hooked device either.

inside classes use uiimagepicker commented out unnecessary code , focused on library , camera buttons. crash happens once device , xcode intertwined. thing once not connected can access library users won't have problem because they'll never have xcode running app.

it should noted when device , xcode hooked can use camera , take pics. problem seems regulated library.

i've seen question asked several times answer

"the permissions inside info.plist have set"

in situation permissions set inside info.plist:

here pic of switch set "on" inside simulator's settings page. couldn't take photo of actual device's setting's page on there both camera , photos switches set "on"

my code:

mycontroller: uiviewcontroller, uiimagepickercontrollerdelegate, uinavigationcontrollerdelegate{   fileprivate var imagepicker = uiimagepickercontroller()  override func viewdidload() {         super.viewdidload()          imagepicker.delegate = self }  @ibaction fileprivate func librarybutton(_ sender: uibutton){          self.imagepicker.sourcetype = uiimagepickercontrollersourcetype.photolibrary         self.imagepicker.allowsediting = false         presentviewcontroller(self.imagepicker, animated: true, completion: nil)  }  @ibaction fileprivate func camerabutton(_ sender: uibutton){          self.imagepicker.sourcetype = uiimagepickercontrollersourcetype.camera         self.imagepicker.allowsediting = false         present(self.imagepicker, animated: true, completion: nil)  }  func imagepickercontroller(_ picker: uiimagepickercontroller, didfinishpickingmediawithinfo info: [string : any]) {          if let myimage = info[uiimagepickercontrolleroriginalimage] as? uiimage{             imageview.image = myimage         }         else if let myimage = info[uiimagepickercontrollereditedimage] as? uiimage{             imageview.image = myimage         }         else{"uiimagepicker problem")         }          imagepicker.dismiss(animated: true, completion: nil)     }  func imagepickercontrollerdidcancel(_ picker: uiimagepickercontroller) {     imagepicker.dismiss(animated: true, completion: nil) } } } 

i tried:

fileprivate var imagepicker:uiimagepickercontroller?  @ibaction fileprivate func librarybutton(_ sender: uibutton){          self.imagepicker = uiimagepickercontroller()         self.imagepicker?.delegate = self         self.imagepicker?.sourcetype = uiimagepickercontrollersourcetype.photolibrary         self.imagepicker?.allowsediting = false         present(self.imagepicker!, animated: true, completion: nil)  }  @ibaction fileprivate func camerabutton(_ sender: uibutton){          self.imagepicker = uiimagepickercontroller()         self.imagepicker?.delegate = self         self.imagepicker?.sourcetype = uiimagepickercontrollersourcetype.camera         self.imagepicker?.allowsediting = false         present(self.imagepicker!, animated: true, completion: nil)  } 

i tried:

fileprivate let imagepicker:uiimagepickercontroller?  override func viewdidload() {         super.viewdidload()          imagepicker = uiimagepickercontroller()         imagepicker!.delegate = self }   @ibaction fileprivate func librarybutton(_ sender: uibutton){          imagepicker!.sourcetype = uiimagepickercontrollersourcetype.photolibrary         imagepicker!.allowsediting = false         present(imagepicker!, animated: true, completion: nil)  }  @ibaction fileprivate func camerabutton(_ sender: uibutton){          imagepicker!.sourcetype = uiimagepickercontrollersourcetype.camera         imagepicker!.allowsediting = false         present(imagepicker!, animated: true, completion: nil)  } 

this same crash info keep getting once device , xcode hooked up:

i don't have unwind segue anywhere in project i'm unsure of why says that. regardless if works on simulator should work on phone or if doesn't work on phone shouldn't work on simulator either. below here snippet of crash report , stack trace.

bug report:

i deleted app device, shut down xcode, relaunched it, accepted ok give access library, , same problem.

any idea of problem is?

ash furrow helped me out non obvious problem , possibly api bug. posted pics people unfamiliar process resolve it.

it turns out inside breakpoint navigator had all exceptions activated. reason when app hooked xcode , uiimagepicker presenting photo library, exceptions breakpoint triggered , there slight delay caused app crash. delay milliseconds long enough app thought there problem. ash said never saw before , said there possibly corrupted jpg photo in photo library again wild guess. simple solution deactivate or delete exceptions breakpoint , problem resolved. did possibly api problem because still causing odd crash.

it should noted said exceptions break point keep activated because find exceptions earlier later. forgot explanation in detail it's best keep on , if run problem deactivate it.

steps resolve uiimagepicker library presentation crash deactivating exceptions breakpoint:

1. on left side of screen in navigation pane, 7th icon left looks arrow breakpoint navigator

2. the exceptions breakpoint activated/highlighted blue

3. to deactivate exceptions either click highlighted blue arrow or right click on word all exceptions , list either choose disable or delete

4. assuming either choose disable or click blue arrow, deactivated

5. obviously if choose delete erased form breakpoint navigator if want add again (or if never had begin with) still have inside breakpoint navigator (step 1) , in lower left corner of pane press plus button , choose exception breakpoint add it.
