If the iPhone Simulator option is selected then the app will run within the simulated environment when it is built. To instruct Xcode to install and run the app on device itself, simply change this menu to the iPhone Device setting. Assuming the device is connected, click on the Build and Run button and watch the status updates at the bottom of the window as Xcode compiles the source code. Once the code is built, Xcode will need to sign the app using your developer certificate. If prompted with a message that reads “codesign wants to sign using key “<key name>” in your keychain select either Allow or Always Allow (if you do not wish to be prompted during future builds). Once signing is complete the status will change to “Installing <appname>.app on iPhone…”. After a few seconds the app will be installed and will automatically start running on the device where it may be tested in a real world environment.
