iOS 9 Crashes with styleClass All Over

[cliftonlabrum]

I just fired up my Pixate-enabled app in the iOS 9 simulator, and it crashes all over the place with messages like:

-[UITextField preventStyling]: unrecognized selector sent to instance 0x7fa8b96d6330

Failed to set (styleClass) user defined inspected property on (UITextField): -[UITextField preventStyling]: unrecognized selector sent to instance 0x7fa8b96d6330

and...

-[UISearchBarTextField preventStyling]: unrecognized selector sent to instance 0x7fda5af39350

Anyone know why this preventStyling thing is creating issues? I don't explicitly using it anywhere in my code. It appears to get called when using styleClass.

Oh man, I can't believe no one else has run into this. iOS 9 is about to hit, and if the Simulator is accurate, my app will be completely unusable because of Pixate.

Anyone successfully using styleClass runtime attributes on iOS 9?

The problem appears to be specific to UITextField. I tried removing any styles that reference them but the same thing happens. The mere presence of a UITextField in a view causes the crash.

I'll take a look today.

It only seems like it is a simulator problem?

[forrestgrant]

+1, and I also notice that this is only a problem in the simulator.

[cliftonlabrum]

Yep, Simulator only. Pretty crippling for any development work, though.

+1 Same here. It was working fine until I upgraded to El Capitan. Was working on Xcode 7

This is quite strange. Here is the line that is causing the issue:

    BOOL preventStyling =
        ([styleable respondsToSelector:@selector(preventStyling)] && [styleable preventStyling]) ||
        ([styleable respondsToSelector:@selector(viewStylers)] == NO);

And the error message:

-[UITextField preventStyling]: unrecognized selector sent to instance 0x7fe905185b40

UITextField should not recognize the selector preventStyling, so this one should not be called, since the && operator should not execute the right-hand part of the expression.
BUT: setting a breakpoint it turns out that [styleable respondsToSelector:@selector(preventStyling)] is true... Why? No clue.
