The answer is correct, Display Zoom is not available as an option in the current Xcode 7 iOS simulator settings. However, it is actually possible to 'simulate' Display Zoom when running your app in the simulator.
Background
When building a typical project for iPhone, you generally specify a
LaunchScreen.storyboardfile and/or launch images inImages.xcassetsfor the iPhone 4/4s (2x), iPhone 5/5s (Retina 4), iPhone 6/6s (Retina HD 4.7) and iPhone 6+/6s+ (Retina HD 5.5) and set those details in the project's settings. (See image below.)When Display Zoom is turned ‘on’ for a iPhone 6/6s device, the device runs the app as if it was running on an iPhone 5/5s sized screen, upscaling the app x1.172 to fit the iPhone 6/6s display. (Similarly, when Display Zoom is turned ‘on’ for a iPhone 6+/6+s device, the device runs the app as if it was running on an iPhone 6/6s sized screen, upscaling the app to fit the iPhone 6+/6+s display.)
Simulating Display Zoom on the iOS Simulator
To simulate Display Zoom for example using the iPhone 6 simulator in Xcode:
1 - Remove the
LaunchScreen.storyboardfile.2 - Remove both the
Retina HD 4.7andRetina HD 5.5launch images inImages.xcassets. (Make sure to keep theRetina 4launch image.)3 - Remove the reference to the ‘Launch Screen File’ in your Xcode project’s settings, under ‘General’, under ‘App Icons and Launch Images’.
4 - Select the iPhone 6/6s simulator, and then 'Run' your app.
Running your app
When the simulator runs your app, it will detect that no launch images are present for iPhone 6/6s, so it will presume it must be an iPhone 5/5s app and launch it into the simulator upsampling a iPhone 5/5s sized screen to fit the iPhone 6/6s screen, just as the Display Zoom setting would display it!
Display Zoom is not available in the simulator (as of Xcode 6.0).
