App Settings

Generally, all Apps created these days are built to run in the background. With this checkbox marked, your App will restart at the launch screen every single time it is closed and reopened. And it will not display within the multitask bar on your iOS device.

If you leave the checkbox blank, then if you should open a subwire in your App and close the App. When you opened the App again, it would be running in the background and open where you left off in the App.
