applicationDidFinishLaunching()
Tells the delegate that the launch process is almost done and the app is almost ready to run.
Declaration
optional func applicationDidFinishLaunching()Discussion
WatchKit calls this method after the launch cycle has finished and before your app’s interface is active. Use this method to complete your watchOS apps initialization and prepare it to run. For example, a page-based app could use this method to call the reloadRootControllers(withNames:contexts:) method to specify the initial set of interface controllers to display.
