With an all-new design that looks great on macOS Big Sur, Xcode 12 has customizable font sizes for the navigator, streamlined code completion, and new document tabs. Xcode 12 builds Universal apps by default to support Mac with Apple Silicon, often without changing a single line of code.
Designed for macOS Big Sur.
Xcode 12 looks great on macOS Big Sur, with a navigator sidebar that goes to the top of the window and clear new toolbar buttons. The navigator defaults to a larger font that’s easier to read, while giving you multiple size choices. New document tabs make it easy to create a working set of files within your workspace.
Document tabs.
I am using Xcode10.2 on High Sierra 10.13.6, and can build several projects for my iPhone 5s and 6s Plus which working on iOS12.2. The process is similar to Damnum’s. Change the name of working Xcode like Xcode10.1. Download Xcode 10.2 and copy it into Applications folder. (The name is of course Xcode.). All downloads are hosted by Apple. Links on this site take you directly to Apple’s download pages. This is not an official Apple website. Please consider donating to help maintain it. Looking for an API?
The new tab model lets you open a new tab with a double-click, or track the selected file as you click around the navigator. You can re-arrange the document tabs to create a working set of files for your current task, and configure how content is shown within each tab. The navigator tracks the open files within your tabs using strong selection.
Navigator font sizes.
The navigator now tracks the system setting for “Sidebar icon size” used in Finder and Mail. You can also choose a unique font size just for Xcode within Preferences, including the traditional dense information presentation, and up to large fonts and icon targets.
Code completion streamlined.
A new completion UI presents only the information you need, taking up less screen space as you type. And completions are presented much faster, so you can keep coding at maximum speed.
Redesigned organizer.
An all-new design groups all critical information about each of your apps together in one place. Choose any app from any of your teams, then quickly navigate to inspect crash logs, energy reports, and performance metrics, such as battery consumption and launch time of your apps when used by customers.
SwiftUI
SwiftUI offers new features, improved performance, and the power to do even more, all while maintaining a stable API that makes it easy to bring your existing SwiftUI code forward into Xcode 12. A brand new life cycle management API for apps built with SwiftUI lets you write your entire app in SwiftUI and share even more code across all Apple platforms. And a new widget platform built on SwiftUI lets you build widgets that work great on iPad, iPhone, and Mac. Your SwiftUI views can now be shared with other developers, and appear as first-class controls in the Xcode library. And your existing SwiftUI code continues to work, while providing faster performance, better diagnostics, and access to new controls.
Universal app ready.
Xcode 12 is built as a Universal app that runs 100% natively on Intel-based CPUs and Apple Silicon for great performance and a snappy interface.* It also includes a unified macOS SDK that includes all the frameworks, compilers, debuggers, and other tools you need to build apps that run natively on Apple Silicon and the Intel x86_64 CPU.

Updated automatically
When you open your project in Xcode 12, your app is automatically updated to produce release builds and archives as Universal apps. When you build your app, Xcode produces one binary “slice” for Apple Silicon and one for the Intel x86_64 CPU, then wraps them together as a single app bundle to share or submit to the Mac App Store. You can test this at any time by selecting “Any Mac” as the target in the toolbar.
Test multiple architectures.
On the new Mac with Apple Silicon, you can run and debug apps running on either the native architecture or on Intel virtualization by selecting “My Mac (Rosetta)” in the toolbar.
Multiplatform template
New multiplatform app templates set up new projects to easily share code among iOS, iPadOS, and macOS using SwiftUI and the new lifecycle APIs. The project structure encourages sharing code across all platforms, while creating special custom experiences for each platform where it makes sense for your app.
Improved auto-indentation
Swift code is auto-formatted as you type to make common Swift code patterns look much better, including special support for the “guard” command.
StoreKit testing
New tools in Xcode let you create StoreKit files that describe the various subscription and in-app purchase products your app can offer, and create test scenarios to make sure everything works great for your customers — all locally testable on your Mac.
Get started.
Download Xcode 12 and use these resources to build apps for all Apple platforms.
1) Prerequisites
Before installation, ensure your macOS operating system is current. Select menu -> 'System Preferences' -> 'Software Update' and check whether any OS updates are available. If so, install them first and only then proceed with the rest of this installation guide. In order to install QtCreator, you need to have a version of MacOS that is >= 10.13. If this is not possible for you, please reach out to the course staff ASAP.
2) Install Xcode tools
Apple's developer tools are bundled as a part of Xcode. Installing Xcode provides the C++ compiler that is used by Qt Creator.
To choose the correct Xcode installation, you need to know your macOS version. Select menu -> 'About This Mac' and read the macOS version number.
If your macoS version is Catalina >= 10.15, you can install the latest Xcode directly from the App Store by following these steps:
Select menu - > 'App Store…' and search for Xcode. Download and install the app.
If your macOS version is 10.14 or older, you need to install an older Xcode. Older versions of Xcode are available at Apple Developer Downloads by following these steps
- Visit https://developer.apple.com/downloads/ and sign in with your Apple ID.
- Search for Xcode and select the version that is compatible with your macOS version:
- For macOS 10.14, use Xcode version 11.3
- For macOS 10.13, use Xcode version 10.1
- Do not chose any version labeled 'beta' or 'preview'
- If the Apple developer site disallows you from accessing downloads, create a new Apple ID and try again. (This can happen if your Apple ID was created when your age was too young for some features?)
- Download the appropriate version, open the archive, launch the Xcode installer, and follow through the installer steps.
- After the installer finishes, drag the XCode application into your Applications folder.
Xcode is a very large app, so the download and installation will take some time, and can be anywhere from 1-4 hours depending on your network connection speed. If your computer does not have enough space for Xcode, or if the download will take prohibitively long (more than 24 hours) due to the quality of your internet connection, reach out to the Head TA for alternate installation instructions.
3) Run Xcode once
After downloading Xcode, you have to launch the Xcode application one time to install its components.You can open Xcode using Spotlight (the magnifying glass at the top right of your screen) and typing in 'Xcode'.Click 'Agree' to accept the License Agreement and enter your password if prompted. Watch the progress bar 'Installing components…'. When it finishes, quit Xcode. You will not need to launch Xcode again for this course.
4) Download the Qt Creator installer
The Qt Creator official download site is https://www.qt.io/download-qt-installer.When you go to this site, it should detect that your computer is running MacOS and recommend the installer 'Qt Online Installer for Mac OS'. Click the green 'Download' button to download the installer.
5) Run the Qt Creator installer
The downloaded installer is named something like qt-unified-mac-version.dmg. Double-click to mount the disk image and launch the installer.
The graphical installer launches and walks you through a set of steps. For most steps, you can use the default settings and simply click 'Next' or 'Agree' to move on, with the following exceptions:
- At the Qt Account step, you will have to create your own Qt Account.
- At the Select Components step:
- Select the highest-numbered Qt version. For Fall Quarter 2020, the version number must be at least Qt 5.15.0. Do not select any version labeled 'Preview' or 'Alpha' or 'Beta'.
- IMPORTANT: You must also select the macOS kit component. Expand the 'Qt' triangle, then expand the triangle with Qt version number, then click the checkbox labeled 'macOS'. You can un-check every other checkbox except for 'macOS', as shown in the screenshot below.
6) Install CS106 specific components
After installing Qt, you must install the CS106-specific components and do a complete build and run cycle to confirm all is working properly.
Download CS106 project and extract
- Download this archive file: 📦 CS106.zip
- Un-zip the download contents (on a Windows computer, click 'Extract all') to a location of your choice. You should have a folder named
CS106with several files and folders inside.
Open and configure CS106 project
A Qt Creator project includes a file named with a .pro extension. Double-clicking the .pro file opens the project in Qt Creator.
Find the
CS106.profile and open it now.- When opening a project for the first time, Qt Creator brings up a 'Configure Project' panel for you to select the appropriate build kit (see screenshot below). The default kit should already be selected; it will match the component you selected when installing Qt Creator. Accept the default by clicking the 'Configure Project' button.
- If no kits are shown as available, review the Qt install instructions. You can repeat the steps to re-install if you missed selecting the required components.
Build the program
C++ code must be compiled or built before it is run; this means converting the source code into executable binary code.
- Click the Build icon in the lower-left of the Qt Creator window.
- Watch the build progress meter in the lower-right. The first time you build a project, it can take a minute or more to compile the library code. When the bar turns green, it indicates the program successfully built.
Run the program
Now that the program is built, you are ready to run it.
- Click the Play/Run icon in lower-left of window.
As shown in the screenshot below, the welcome program prints a message to the console window and draws the Stanford logo on graphics window.
Xcode Mac 10.13
✔️ Congratulations, your installation is good to go! You may now discard the CS106 project, you will not need it again.
Xcode Mac 10.13.6
7) Configure settings (optional)
