Good morning, I hope someome can quickly help me (I have done a search for this little issue already). I'm runing XCode 6.4 on OSX 10.11 El Captian Beta 1. When running apps (Any App) in the iOS Simulator I'm getting terrible lag when pressing keys on the keyboard. it takes a good few seconds for the simulated app to respond. I put together a dead simple "Heres a text field, enter some text" app and it behaves in the same way.I'm pretty new to development so I'm not sure if I'm missing somethign blindingly obvious. Can anyone cleverer than me help?

Cheers

Hi Tanjuakio,

Did you solve your problem? I've got the same kind of lag and wonder if there is any workaround?

Thanks.

I'm a newbie IOS developer, experiencing intolerable (6 sec.) keyboard sluggishness in the simulator. Otherwise the simulator behaves without sluggishness. My environment is OSX 10.11, Simulator v 10.0, 6G ram,2.8 GHz Intel Core 2 Duo processor. Perhaps I just need more horsepower in my workstation? Are there any tips for resolving this?

I'd at least max the physical ram in that machine. 6 gb is below marginal, IMO.

Please kick off a 'sudo sysdiagnose -q' in Terminal and then *immediately* reproduve the lag issue. It may take you a few times to get it right, but the 6s lag *must* fall within the first 10 seconds of initiating the sysdiagnose.

Then file a radar at http://bugreport.apple.com, and reference the bug number in this thread, so I can easily connect the dots.
