I am developing an iOS application and thanks to Xcode's "output log" I've been able to fix lots of bugs and such.
When I run my iOS application without Xcode, sometimes it crashes. However, it is hard to tell why did it crash since my device was not connected to Xcode. So I was wondering, when I run my iOS application, is there an output log like Xcode's stored somewhere within the iOS device I can retrieve? Or do I definitely need Xcode? Or perhaps there are other ways?
