If the first function definition has NSObject: AnyObject, change it so it reads NSObject: NSDictionary.
These functions are places to add code to save data, but we will only use the first one:įunc applicationWillResignActive(application: UIApplication)įunc applicationDidEnterBackground(application: UIApplication)įunc applicationWillEnterForeground(application: UIApplication)įunc applicationDidBecomeActive(application: UIApplication)įunc applicationWillTerminate(application: UIApplication)
If your application supports background processing, then applicationDidEnterBackground is called, otherwise applicationWillTerminate. Here’s a list of functions that are stubbed in AppDelegate.swift. This is where you should pause tasks, disable timers, etc. For instance, if your App is in use and the phone rings, then the function applicationWillResignActive will be called. It has a bunch of functions called by iOS. In iOS, a delegate is a class that does something on behalf of another class, and the AppDelegate is a place to handle special UIApplication states. The two source code files are AppDelegate.swift and ViewController.swift. Remove the key that starts with, “Main storyboards file name.” If you’re following along and have created a new app, there will be a Main.storyboard file in the Project Files list. Upload Your ResumeEmployers want candidates like you. But if you run it at the outset, you’ll just get a blank screen-you’ll have to add more code to make it do anything. These assets are the minimum you need to a build an app capable of running. It will contain two source code files to start, as well as two ist files that hold information about your App and a storyboard file (which we won’t need for this example).
#SWIFT SHARE VARIABLE APPDELEGATE SOFTWARE#
After filling in a few details, the software will create a project that, in my case, I named FirstExample. To build a Swift app, first, you’ll create an Xcode project and select Swift as the language. After that, open the project files and load them into Xcode.
#SWIFT SHARE VARIABLE APPDELEGATE INSTALL#
Before we start, please download the project files and (if you are a registered Apple developer with the latest Xcode beta) install them. (You need to be a registered developer in order to test your Swift apps on your iPhone, although you don’t need to be one in order to create and run those same apps on an iPhone or iPad emulator.)įor the purposes of this tutorial, I’m using a beta version of XCode 6 (as of this writing, now up to GM seed). In order to develop and run Swift apps, you should have iOS 8 and version 6 of Apple’s IDE Xcode.
At the time of writing, you can only program in Swift if you are a registered iOS developer. You need a Mac that can run OS X Mavericks.
#SWIFT SHARE VARIABLE APPDELEGATE HOW TO#
This is the first of a few articles that show how to program iOS apps using Swift.Ĭlick here to find Swift development jobs. While Objective-C remains popular, developers frequently complain about how difficult it is to use Swift’s features will supposedly eliminate at least some of those issues.ĭespite its ease of use, developers will still need to spend some time learning how the language works. Earlier this year, Apple executives unveiled Swift, which is meant to eventually replace Objective-C as the programming language of choice for Macs and iOS devices.
