Hi, I am having a similar issue. Until now, I still haven't located precisely which piece of code is responsible for the whole crash of the app... The only thing that I am doing is to instantiate a ListView with static content. And I get - sometimes - this error. I am using Ti 4.1.0.GA on iOS 8.3 on the iPad 2 Simulator. [ERROR] The application has crashed with an uncaught exception 'NSGenericException'. [ERROR] Reason: [ERROR] *** Collection <__NSArrayM: 0x7c14a990> was mutated while being enumerated.

@Matthias Benkort I have exactly the same problem! What I found is that the crash seems to do with *ListView templates*. See my test result matrix below. ||iOS 8.2 simulator||iOS 8.3 simulator|| |ListView not display|Crash| It is happening so randomly - I will open another JIRA with ListView scenario tonight
It needs to be treated urgently! Now I have more places crashing my app due to this unclear problem. *Collection <__NSArrayM: 0x7c14a990> was mutated while being enumerated.*
For the moment, downgrading to 4.0.0.GA solved the issue on my side. So, it's likely to be a regression introduced with 4.1.0.GA. Also, I'm not that sure about the templates. I've tried to put only an empty ListView in an xml view file (I am using Alloy 1.6.2), without any template and It crashed in the exact same way (Maybe because of a default template or something related?) Hope those information will help.
We need this fixed ASAP.
[~KtorZ] [~jialhe85@gmail.com] can someone raise a Jira ticket? It will be difficult to identify the crash scenario you talk about without reproducing the actual error. To be clear, those suffering the ImageView.images crash could use as _Work Around_ setting images array after ImageView creation and remove it from createImageView() instance for now, i.e.
var theImageView = Ti.UI.createImageView ({ top: 100, height: 40, width: 40, //images: images, }); // theImageView.images = images;PR: https://github.com/appcelerator/titanium_mobile/pull/6983
