Xcode 4.3.2, issue with running on simulator
I have found by chance, it is not a solution by any means -
When xcode hangs, saying it is running the app, but nothing is on simulator, opening the simulator from the dock by clicking on the dock icon (not using command+tab) seems to work.
It is very weird,but it works; atelast till xcode fixes it.
xcode 4.3.2 process hangs
I was having similar issues with Xcode 4.3.2. I fixed them by doing the following:
Launch Xcode.
Close any open projects.
Open Organizer.
Delete project form left panel using the gear icon on the bottom left. Select "Remove from Organizer...". This clears all the data about your project that Xcode has cached (indexes, DerivedData, Snapshots, etc.).
5). Re-open project.
Since doing this, my Xcode hanging issues have disappeared.

Change the debug option from LLDB to GDB by editing the scheme.

I hope this could help you.
Xcode 4.6 hangs regularly after running project in iPhone Simulator
I have experienced the same thing many times, often many times a day, not necessarily after a crash. So yes, the bug exists and I've reported it to Apple and have continued to revise the report as data warrants. You should do the same (and provide Apple with a Sample report to show what the threads are doing during the hang each time). This has nothing to do with PLCrashReporter; I can experience this problem with a bare template project. Your question, though, seems unconstructive, as no useful answer can be given. Who can possibly tell you why Apple hasn't fixed it? The only people who can tell you that would be Apple, and you know that they won't tell you. So your question is purely rhetorical. :)
