问题
Firstly, thanks for your time and effort.
Just today I started having a random issue in my iOS simulator running an app from Xcode 6. No Xcode update has been installed since I last used the simulator so I don't think it is an issue with an update.
Basically, my simulator is drawing everything HUGE. Like 4x the size it should be. This happens with all simulator devices regardless of iOS version. I'm aware of the window scaling with CMD + 1, 2, 3. That is not the issue. It shows the same no matter the scale. When you click or interact with the screen squares of it flicker. This is what it looks like.
Note that it is not just the application, but also the home screen.
I should also note that this does not seem to be just the simulator. The screen saver on OSX with the words and definitions also is entirely too large. I haven't noticed it in any other application though.
I have done everything I could think of to debug the issue. I deleted Xcode and reinstalled it with a restart in between. I have created a new user account on my machine and ran a boilerplate app on the simulator and it displayed the same way. I've changed my screen resolution to see if that resolves the issue. I cleared the mysterious PRAM. None of these solved the issue or made it better or worse.
Again, thanks for your time. It is appreciated.

For me pressing command + 2 or command + 3 when the ios simulator opens up solve the problem. Pressing the above keys do scaled down the simulator size.

I recently started and I had the same issue. You simply have to change the scale. When the iOS Simulator opens, navigate to Window and change the scale; 50% worked for me.
