xcode5 iOS Simulator failed to install the application

问题

Recently i installed X-Code 5 on my new Mac-mini, and created a iOS project with "Single View Application" template.(I haven't added any code). when i run the application i got the error "iOS Simulator failed to install the application." The deployment target and Base SDK are set to iOS 7.

The simulator screen is blank as [in this stack overflow question][1]

also the following Simulator menu options are not working.

1.Debug->Open System log

2.Hardware->Home,Lock & Toggle in call status bar

Here is the Simulator error log.

    iPhone Simulator[804] <Error>: Could not lookup service com.apple.iphonesimulator.bridge: 3
    iPhone Simulator[804] <Error>: Error communicating with SimulatorBridge: NSObjectNotAvailableException - Unable to connect to SimulatorBridge
    iPhone Simulator[804] <Error>: Could not lookup service com.apple.iphonesimulator.host_support: 3
    iPhone Simulator[804] <Error>: Unable to update keyboard layout because we were unable to connect to the host_support mach service.

Thanks in advance.
