Silly question, but.. I am not been able to see the device appearance when running the iPhone simulator. I don't remember after which XCode update this started but the iPhone simulator shows only as a simple window without showing the device case like it used to be (see this image).
That's how my simulator looks like:
Is there a way to make it look like an actual iPhone 5?
EDIT: Unfortunately in my hardware->device options I see only iPhone retina (which is currently selected), but there are no more options. So it seems like the default beheaviour to look like a thin window, unless I missed out some other configuration.
Here is what I see overlayed to a user answer.
The Simulator window only shows an iPhone (4/4s) bezel when:
The simulated device is a 3.5 inch non-Retina iPhone, and
The window scale is 100%.
In Xcode 5, you can't do the first one unless you download the iOS 6.1 simulator, because 3.5 inch non-Retina devices are not supported by iOS 7.
(For simulated devices other than 3.5-inch non-Retina, you'll also see a bezel at 100% scale, but this bezel doesn't look exactly like any particular device.)
