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.To become a macOS developer, you will need two things: #Download xcode for mac 10.15 series# You’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. But this is not a requirement until you are ready to send your app out to the world, and even then, only if you want to distribute through 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. 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. 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. Once it has downloaded and installed (which may take a while – it is quite large) open it from your Applications folder. The first time you run Xcode, and after every major update, it will ask you for permission to install additional components. #Download xcode for mac 10.15 install#Įnter your password and allow Xcode to install these components.įollowing 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. You should see a Welcome to Xcode window – if you don’t see it, choose Welcome to Xcode from the Window menu.Ĭlick Create a new Xcode project and when the next dialog appears, choose macOS from the tabs across the top. 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. Uncheck all the other options.Ĭlick Next and Create to save your new app project. Xcode has created the basic template for your app with all the required files. At this stage, it is fun to run the app and see how much you get for free.Ĭlick the Play button in the toolbar to run the app or use the Command-R shortcut. 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. You should now see a blank window but don’t be disappointed – have a look at what you can already do: Developer mode allows Xcode to attach a debugger to running processes – which will be extremely useful when building your application! You’re safe to select Enable, at which point you may have to enter your password. The window is resizable, it can be minimized and made full screen. There is a complete set of menus, many of which already work without you doing anything.īut now it’s time for you to make the display a bit more interesting, so quit the app and go back to Xcode.Xcode packs a lot of features into a small package, so not everything is visible at one time. To be an efficient Xcode user, you need to know where everything is - and how to get to it. When you open a new project in Xcode, you have a window with a toolbar and three main panels. The left panel is the Navigator panel and has 9 display options across the top. 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. You design the user interface using a Storyboard.
