Only once per week? Lucky you. Sometimes XCode has crashed for me several times per hour. Sometimes it works for a while. Sigh Apple [1]. The fact XCode uses clang as a compiler absolutely rocks.
That said, Visual Studio 2012 just crashed earlier. I guess it was some bug in Window splitting or something, did some unusual things with that just before the crash. VS2012/2015 seems to be generally stable. Visual Studio C++ IDE context operations, like finding references just doesn't work well at all. It finds so many totally irrelevant items.
Excited to try VS2015 with Clang support for Windows applications, with official support.
[1]: When it comes to personal experience, Apple's recent software quality seems to be shoddy. For example USB3 mass storage is stable only for a few minutes before a forced USB stack reset on my El Capitan Macbook Pro retina 13" 2015. Sigh. Impossible to do things like run virtual machines off USB storage on a relatively new $2k machine... At least without booting to Linux or Windows. Things like these make me seriously consider to stop using OSX as my primary machine.
