Xcode breaks on performSegueWithIdentifier:sender:

[jpcguy89]

SWRevealViewController works amazingly. I just have one minor irritation I would like to see fixed. Every time I run my app, if I have breakpoints enabled it always breaks twice on line 1713 in SWRevealViewController.m

[self performSegueWithIdentifier:SWSegueRightIdentifier sender:nil];

It's not a fatal error, and I'm not sure why Xcode is throwing an exception, but it is.

Thanks!

I think you have to clear the project (Menu: Product->Clean and Alt+Product->Clean Build Folder...)

[jpcguy89]

Nope. Followed the exact instructions. Still breaks there.

[iDevelopper]

Verify the segue identifier in the storyboard. It should be sw_front or sw_rear or sw_right

[jpcguy89]

Clarification: You're saying all segues that are going from the "side menu" should have "sw_right" as the segue identifier?

I have "sw_rear" set for the side menu, and "sw_right" set for the initial view controller. The rest have their own unique identifiers.

[iDevelopper]

You must have a sw_front segue for the front view controller. sw_rear is for the left side controller. sw_right for the right side controller.

[jpcguy89]

I apologize, I misspoke. The segue to the initial controller is, in fact, sw_front, not sw_right.

[iDevelopper]

And then? Always the issue? If so, could you upload a project?

[jpcguy89]

Every time. I wouldn't feel comfortable posting the project publicly. I know that's not helpful, but I've been working on this for years and can't even fathom if someone were to publish an app using the code I've written.

[iDevelopper]

Ok, but perhaps can you reproduce the same issue in a sample project?

[jpcguy89]

Yep, was able to reproduce the issue with a new test project. Added a breakpoint to break on all exceptions, ran, and sure enough, it hit that same line of code. RevealViewControllerTest.zip

[iDevelopper]

Added a sw_front set segue to the blue view controller:

RevealViewControllerTest.zip

[jpcguy89]

Any news on this? I believe the issue was still there after you added the segue.

[iDevelopper]

No, I do not have this issue!

[jpcguy89]

And you added a breakpoint for all obj-c and C++ exceptions?

[iDevelopper]

No, why do you want to add a breakpoint?

[iDevelopper]

Ok I see, I added a breakpoint. It is normal because there is no segue with identifier sw_right in the application. But the exception is not thrown. So, no crash...

There is no documented method in Apple Documentation to check if a segue exist, so the author used a workaround!
