how do I use this variable in ViewController. Return new HttpResponseMessage(HttpStatusCode.I have the variable I created in appDelegate. The AppDelegate is supposed to supply the initial view controller with an injection of my data-class called 'ModelController', and then I pass it along. Public HttpResponseMessage ExecuteResult() I followed the tutorial called 'The Right Way to Share State Between Swift View Controllers' on the website 'EnvatoTuts+' to the dot, but my initial view controller is a Navigation Controller. Return base.ExecuteAsync(cancellationToken) Var jsonFormat = accept.Any(h => h.Equals(acceptJson)) Public override Task ExecuteAsync(CancellationToken cancellationToken) Thanks to Darrel Miller, I for now use this solution. I have no idea how we approach browser vendors about this, but I feel like it would be good to start doing this. And I, for one, do not feel like it should be necessary to write in more languages than HTML, JavaScript, CSS, and PHP to get the same experience a user would get from a native application. Users should not have to be inundated with keeping more software than just their web browser updated to have websites run well and securely. I don't want to have my users install third/fourth party plugins to enable a little more control/access to their I/O. Until web developers are allowed the same control as native application developers over hardware, we will be left at a huge disadvantage over what we can offer our users. Like the UIApplication object, UIKit creates your app delegate object early in your app’s launch cycle so it’s always present. We need to be able to request hardware access from users, in a similar fashion that we can request to access a user's location, or how we can request to send a user push notifications. The app delegate is effectively the root object of your app, and it works in conjunction with UIApplication to manage some interactions with the system. So, after receiving basically zero helpful answers - and finding no further helpful information online, I think I figured out something that we, as developers, NEED to start requesting from browser vendors and w3c. NSMutableArray *yourArrayFromWebResponse = Later some where in any other view or view controller you can get that global array for example lets say you have YourViewController class: NSArray *this_IS_Array_Populated_here_For_Global_Access = initWith.] #define USERDATASINGLETON (UserDataSingleton *) (void)saveInUserDatasingletonWithArray:(NSArray *)array AppDelegate let aVariable appDelegate.value Swift 3.0 let appDelegate as AppDelegate let aVariable appDelegate.someVariable Swift 2.0 let appDelegate UIApplication.sharedApplication ().delegate as AppDelegate let aVariable appDelegate. Static UserDataSingleton *userDataSingletonInstance Instead of only creating an AppDelegate.swift file, a ViewController.swift, a storyboard and some other files, Xcode now creates a new file for you the SceneDelegate.swift file. (NSDictionary implementation file will be some thing like: When you create a new project in Xcode 11, you might notice something that you haven’t seen before. (void)saveInUserDatasingletonWithArray:(NSArray *)array #import UserDataSingleton : *globalArray which you can use all over your application to share data globally (for your case array). First add a file to create AppDelegate class e.g. You can make class as UserdataSingleton which overrides NSObject. The UIApplicationDelegateAdaptor gives the option of using UIApplicationDelegate methods that are traditionally used in UIKit applications.
