I have downloaded the xcode5_GM_seed and install it, but I cannot find iOS7 simulator in components.
Where can I find iOS 7 simulator?

XCode 5 comes with iOS 7 sdk and simulator automatically. However, since iOS 7 is not supported in old "iPhone" and supported in "iPhone Retina..." and "iPad.." so you need to select appropriate iOS simulator in your project... (your old/existing projects seems to be selecting to "iPhone" simulator)
Since iOS 7 does not support non-retina devices, you need to select one of the retina devices to see iOS7 simulator option.
If you can't find a simulator version you're looking for, chances are that you need to download it from the components section. Navigate to Preferences → Downloads and make sure you download all the simulator builds that you may need.
In Xcode preferences > downloads. But until the OS is released, you will need a paid ios developer account.
For Xcode 6: In iOS Simulator, go to Hardware | Device | Manage Devices... Click the + in the bottom left and choose whatever Simulator you want.
