ios - Getting signal sigabrt exception, cant find the error -

so im getting strange sigabrt exception, added exception breakpoint , line i'm getting exception on this:

[self performseguewithidentifier: @"solvesound" sender: self];

by way i'm getting in output.

edit:added soundviewcontroller code:

@interface soundviewcontroller ()  @end  @implementation soundviewcontroller {     sounditem *currentsound; }  - (void)viewdidload {     [super viewdidload];     // additional setup after loading view.   } - (void)viewwillappear:(bool)animated {     [super viewwillappear:animated];      [self.answertextfield becomefirstresponder]; }  - (bool)textfield:(uitextfield *)thetextfield shouldchangecharactersinrange:(nsrange)range replacementstring:(nsstring *)string {     nsstring *newtext = [thetextfield.text stringbyreplacingcharactersinrange:range withstring:string];     if ([newtext length] > 0) {         self.checkbutton.enabled = yes;     } else {         self.checkbutton.enabled = no;     }     return yes; }  - (void)didreceivememorywarning {     [super didreceivememorywarning];     // dispose of resources can recreated. }   @end
