This error you may repeat and seen if you select one of lookup tags. I found this error on iPad with iOS 8.

Getting the same error on iOS 8. Any progress on resolving?

Looks like I've missed the contributor's mistake. At this moment a stable version is here: 75d010e661dbe646e97b5c68101b35538445563b (tagged as 1.0.1) You can use it. Note the issues list though.

Hi Andrey,

Thanks for that link, I downloaded it and ran the demo but the demo has the same crashing issue. It's slightly different in that the lookup tags don't appear immediately but selecting one will still crash it with the error "request for index path for global index when there are only two items in the collection view". I'm using ios8 if that makes any difference. Any ideas what to try to get this working? Happy to try to solve it but might need some guidance.

Thanks, Robert

I approve the crash is still exists. I'd happy to give some advices but it is much time passed since I wrote this code. I'm gonna fix the crash today.

Robert, you can try v1.0.0. It is much stable. It is definitely not an iOS7 bug though.

[kas-kad]

I decided to roolback all changes made after 1.0.0 since there were crucial mistakes made by one of contributor. I have no time to research all the changes made especially that contributor had no respect to original code style making alot of code formatting changes.

[kas-kad]

So now in ver.1.0.0 there is no support of storyboards. But less bugs for sure.

[roberthchapman]

Thanks Andrey, have had a look and yes it's much better. And, worth saying, far better than other tag controls. Can use fine without storyboard support. Will implement now and rate too. However I did spot one bug just now which isn't major but worth pointing out - will create a new issue. Thanks

Oh! Thank you! Thank you very much! I was away on business and could not participate in the discussion and this weekend.
