In the Downloads pane of Xcode's Preferences, download the iOS 7 or 7.1 simulator.

After it is downloaded, go to the Devices window (Window -> Devices) and click the Plus button to make a new simulated device with the system version you want. For example you might decide to make an iPhone 4s that's running iOS 7.

Now you'll be able to choose that device/system as the destination when you build and run.

iOS simulator only list the latest iOS version. How can I set earlier versions

the problem is that you have no other Simulator SDK installed which can be used. As @dorada has mentioned you have to install an older Xcode which in fact doesn't work because you're using Lion. I haven't tried it with Lion but principally it should work like before with Snow Leopard.

I'm referencing to my other answer how to get an older Xcode (don't know if it's still working)

After you have an older Xcode version, mount the image an navigate with terminal to that volume. There should be a hidden folder Packages. open that folder with open . and locate the two .pkg files you need (e.g. iPhoneSDK4_0.pkg and iPhoneSimulatorSDK4_0.pkg) and install both.

They will appear in your root directory and you have to move them to your Developer dir (don't simply overwrite, it will delete all other SDKs. go to the last different folder it should be iPhoneSimulator4.0.sdk\ and copy that one)

DONE (and at that point I have verified it: it works on my Lion. I used the dvd image which I have started backup'ing since 3.2.1)
