Otherwise, keep reading. Take a quick look through the topics to make sure and then skip straight ahead to the next part of the series. If you already have iOS experience, this first part of the series will be a review. If you are new to Swift, this series assumes some Swift knowledge, so first check out our Swift tutorials to get a great introduction. Your Mac is protected from online threats such as Trojans, viruses, adware, and spyware by our award-winning technology and easy-to Computer Programming/MacOS Programming 1 About the platform 2 Types of Software for Mac OS X 2.1 Applications 2.2 AppleScripts 2.3 Automator Workflows 2.4. Easy to use, the Mac virus scan starts with just the push of a button.
Program Install This LaterYou’ll learn how to install this later in this section.Once you’ve built your app, if you want to upload it to the App Store for distribution, you’ll also need to pay for an Apple developer account. Xcode: This is the IDE used to create macOS apps. A Mac running macOS Big Sur: The macOS operating system only runs on Apple computers, so you need a Mac both to develop and run macOS apps.![]() You will need an App Store account to download Xcode even though Xcode is free.Search for Xcode and click the Install button to start the download. Xcode is an IDE (Integrated Development Environment) that includes everything you need to develop macOS, iOS, watchOS and tvOS apps.If you don’t have Xcode already, click on the Apple icon in the upper left of your menu and select App Store… to open the Mac App Store. If you already have a developer account for distributing iOS apps, then you are all set – Apple has merged the developer accounts so that you only need a single account to distribute apps for any Apple devices.Unlike some other platforms, developing for macOS requires the installation of just one tool: Xcode. Running Your AppXcode has created the basic template for your app with all the required files. Uncheck all the other options.Click Next and Create to save your new app project. Select App from inside the Application section and click Next.Give your new app a name – HelloWorld – make sure Storyboard is selected for user interface and that the language is set to Swift. You should see a Welcome to Xcode window – if you don’t see it, choose Welcome to Xcode from the Window menu.Click Create a new Xcode project and when the next dialog appears, choose macOS from the tabs across the top. Enter your password and allow Xcode to install these components.Following the long-standing tradition when learning a new programming language or platform, you are going to start by creating a Hello World! app for macOS.Open Xcode if it is not already running. The first time you run Xcode, and after every major update, it will ask you for permission to install additional components. The Xcode InterfaceXcode packs a lot of features into a small package, so not everything is visible at one time. There is a complete set of menus, many of which already work without you doing anything.But now it’s time for you to make the display a bit more interesting, so quit the app and go back to Xcode. The window is resizable, it can be minimized and made full screen. Developer mode allows Xcode to attach a debugger to running processes – which will be extremely useful when building your application!You should now see a blank window but don’t be disappointed – have a look at what you can already do: You’re safe to select Enable, at which point you may have to enter your password. Xcode will now compile all of the code into machine code, bundle up the resources required by the app and then execute it.Note: The first time you ever build and run an app in Xcode, you might be asked whether you want to Enable Developer Mode on this Mac. Application Scene: The menu bar and items. There are three main areas, each of which also has a textual representation in the Document Outline: Your app already has a storyboard, so go to the Project Navigator and click on Main.storyboard to show it in the Editor panel.Your display has just changed dramatically! In the Editor panel, you can now see the Document Outline and the visual editor for the UI.Have a look at the things you can see in the visual editor. Adding the UIYou design the user interface using a Storyboard. The one you will mostly use is the first one – Project – which lists all the files in your project and allows you to click on any one to edit it.The center panel is the Editor panel and will display whatever you have selected from the Project Navigator.The right panel is the Utilities panel and it will vary depending on what you are looking at in the Editor panel. But the button does nothing, and the label just shows “Label”, so it is time to make things more interactive.Go back to Main.storyboard and click on the button to select it. Try typing in the text field – it already supports all the standard editing shortcuts: copy, paste, cut, select all, undo, redo and so on. You will see these 3 UI elements. Finally, add a Label.Now, build and run the app using the Play button or Command-R. View Controller Scene: Where your UI elements will go.In the Utilities panel, you see a top section with 9 tabs.Right now you want to insert UI elements, so select the Object library which is the plus-sign button.In the filter at the bottom, type “text” to reduce the number of choices, and drag a Text Field into your View Controller Scene.Now filter for “button” and drag a Push Button into the View Controller Scene. To help the users, add some placeholder text to the text field using the Attributes Inspector.Stretch the text field out a bit to allow for long names and position the button to the right of it. For this app, the user is going to type their name in here, and when they click the button, the app will show “Hello name-goes-here!” in the label. Change the title of the button to “Say Hello”.Now click in the text field to select it. Winrar for mac 64 bitThis will create a second editor panel containing the ViewController code.Depending on the size of your monitor, things may be looking a bit cramped now, so use the rightmost button in the Toolbar to hide the Utilities. With the Main.storyboard visible, option-click on ViewController.swift in the Project Navigator. To make those linkages, you are going to use Xcode’s Assistant Editor. Once you are happy with the look of the text in the label, delete the label’s Title so that the label starts off empty.Your app still doesn’t do what you want, but in order for that to work, you need to start adding code and that code has to be able to communicate with the UI. Select the label and in the Attributes Inspector, change the font to System Regular 30.How about making the text red to add even more excitement?You can’t tell how long a name a user might enter, so resize the field to fit the height of that font and to almost fill the width of the window.Build & run the app to check that your UI changes have taken effect. Since the label is going to be important, make it use a larger font. This time, change the Connection popup to Action and set the name to sayButtonClicked. This calls for an instead of an the button and Control-Drag into ViewController.swift as before. Let go and enter nameField in the name box of the popup, then click Connect.Do the same with the label, naming it helloLabel.Looking at the code that Xcode has generated, you see that these are both marked with This is short for Interface Builder Outlet and is how you tell the storyboard editor that these object names are available for linking to a visual object.For the button, the code does not need to have a name for it, but it does need to know when a user clicks the button. Hold down the Control key and drag from the text field into the top of the ViewController class definition. Now type in your name and click the button again to see your own personal greeting. The blobs beside the line numbers indicate a connection to the interface in the storyboard.Click the Say Hello button without entering anything and you will see “Hello World!”. If you had hidden the Navigator, click the toggle button in the top right, or press Command-1 to jump directly to the Project Navigator.Enter the following code into sayButtonClicked.The complete code in ViewController.swift now looks like this. Close the Assistant Editor using the X in the top left corner and switch to ViewController.swift.
