How to use Xcode 12 to build, test, and submit apps
Create a new project or open an existing one
To start developing your app with Xcode 12, you need to create a new project or open an existing one. Here's how:
To create a new project, open Xcode and choose File > New > Project. You will see a list of templates for different types of apps. Choose the one that suits your needs and click Next. You will then need to enter some information about your app, such as the product name, organization name, bundle identifier, language, user interface, and core data. Click Next and choose a location to save your project. Click Create and your project will be ready.
To open an existing project, open Xcode and choose File > Open. You will see a dialog box where you can browse for your project file. Select your project file and click Open. Your project will be loaded in Xcode.
Design your user interface with SwiftUI or UIKit
Once you have your project ready, you can design your user interface with SwiftUI or UIKit. SwiftUI is a modern way to create user interfaces declaratively using Swift code. UIKit is a traditional way to create user interfaces imperatively using storyboards or code. You can choose either one depending on your preference and experience. Here's how:
To design your user interface with SwiftUI, open your project and go to the ContentView.swift file. This is where you can write your SwiftUI code to define your user interface elements, such as text, images, buttons, lists, etc. You can also use the canvas to preview your user interface in real time and make changes using the inspector or the library.
To design your user interface with UIKit, open your project and go to the Main.storyboard file. This is where you can use the Interface Builder to drag and drop user interface elements from the library to the canvas. You can also use the inspector to modify the properties and constraints of your user interface elements. You can also write code in the ViewController.swift file to add functionality and logic to your user interface elements.
Write your code with enhanced code completion and syntax highlighting
After designing your user interface, you can write your code with enhanced code completion and syntax highlighting in Xcode 12. Code completion is a feature that helps you write your code faster and more accurately by suggesting possible completions for what you are typing. Syntax highlighting is a feature that helps you read your code easier by coloring different parts of your code according to their meaning. Here's how:

To use code completion, open your project and go to any Swift file where you want to write your code. Start typing something and you will see a list of suggestions pop up below your cursor. You can use the arrow keys or the mouse to select a suggestion and press Enter or Tab to insert it into your code. You can also press Esc to dismiss the suggestion list.
To use syntax highlighting, open your project and go to any Swift file where you want to read your code. You will see that different parts of your code are colored differently according to their meaning. For example, keywords are blue, strings are green, comments are gray, etc. You can also customize the colors and fonts of your code in the Preferences > Fonts & Colors menu.
Test your app with simulators, debuggers, and instruments
Before submitting your app to the App Store, you need to test your app with simulators, debuggers, and instruments in Xcode 12. Simulators are virtual devices that let you run your app on different types of Apple devices and operating systems. Debuggers are tools that let you find and fix errors and bugs in your code. Instruments are tools that let you measure and optimize the performance and memory usage of your app. Here's how:
To use simulators, open your project and click on the scheme pop-up menu in the toolbar. You will see a list of available simulators for different devices and operating systems. Choose the one that you want to test your app on and click on the Run button. Your app will launch on the simulator and you can interact with it as if it was a real device.
To use debuggers, open your project and click on the Debug navigator in the navigator area. You will see a list of breakpoints and watchpoints that you have set in your code. Breakpoints are points where your app will pause execution when it reaches them. Watchpoints are points where your app will pause execution when a variable or expression changes value. You can use the debugger console and the variables view to inspect and modify the state of your app when it is paused.
To use instruments, open your project and choose Product > Profile. You will see a list of templates for different types of analysis, such as CPU, Memory, Energy, etc. Choose the one that you want to perform on your app and click on the Record button. Your app will launch on a device or simulator and instruments will start collecting data about its performance and memory usage. You can use the timeline, the detail pane, and the inspector to analyze and optimize your app.
Submit your app to the App Store with Xcode Organizer
After testing your app, you can submit your app to the App Store with Xcode Organizer. Xcode Organizer is a tool that helps you manage your app's certificates, profiles, devices, archives, and submissions. You can use Xcode Organizer to upload your app's binary, metadata, and screenshots to the App Store Connect website. Here's how:
To use Xcode Organizer, open your project and choose Product > Archive. This will create an archive of your app that contains all the necessary files for submission.
Once the archive is created, go to Window > Organizer and select your archive from the list.
Click on the Distribute App button and choose App Store Connect as the destination.
Follow the instructions to sign in with your Apple Developer Program account and select your team.
Choose whether you want to automatically manage signing or manually manage signing for your app.
Review the summary of your app's information and click on Upload.
Wait for the upload process to complete and check for any errors or warnings.
Go to the App Store Connect website and sign in with your Apple Developer Program account.
Select your app from the list and review its status and details.
If everything is OK, click on Submit for Review and wait for Apple's approval.
