Hi, I've been using the SDK (1.3.1) via CocoaPods in one of my projects.
I've just had a user reporting this crash:
ZBarReaderView.m line 585
-[ZBarReaderView didTrackSymbols:]
Apparently the reason is that the syms array was mutated while being enumerated:
Fatal Exception: NSGenericException
*** Collection <ZBarSymbolSet: 0x170422e00=""> was mutated while being enumerated.
Hi, we are also facing the same issue. I tried resolving the issue by intretraing the mutable copy of the ZBarSymbolSet by regular for loop and still its crashing. Did you find other way to fix the issue ?
Thanks in advance.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Hi,
I am seeing the same thing from the same version,
Seems like the enumeration that happens inside is not always secure to do.
I think the easiest fix is simply change the fast enumeration for a simple for loop.
I would send a pull request but I don't get the Mercurial thing, sorry.
Thanks,
Pablo

Hi Pablo, thanks for the suggestion. I tried "for" loop solution on mutable copy of the original ZBarSymbolSet. Still its crashing. Can you please share your thoughts ?
Thanks,

I was wondering if you've seen this before or if you know of a way to fix this.

Certainly! You can make a copy of the syms array and iterate over the copy to avoid mutation during enumeration in three lines dgme
