_BSMachError XCode 7 Beta

Question

I am getting the following error when I am running my code in Xcode7 with Swift2, after presenting a view controller through a push segue:

_BSMachError: (os/         


        

Answer 1

Dismissing view controller prematurely might cause this.

[self dismissViewControllerAnimated:YES completion:NULL]; 
//

This throws _BSMachErrors

vs

//
[self dismissViewControllerAnimated:YES completion:NULL]; 

Now, the _BSMachError is gone.
