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.
- Experience Mac to the fullest with a refined new design. Enjoy the biggest Safari update ever. Discover new features for Maps and Messages. And get even more transparency around your privacy. Bold new experience. Unparalleled power. Legendary ease of use. Limitless creativity. MacOS Big Sur brings a refined new.
- I am using Mac OS Sierra 10.12.6 and downloaded the xCode version 10.2.1 and it's can't using now. Can anyone recommend for me a version of Xcode comfortable with this version of Mac os? Thanks – huykon225 Jul 19 '19 at 17:44.
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.
Specifically, get 9.2. This is the recent version that works with mac OS Sierra. Edit: Xcode 9.2.1 is no longer an available version. 2: Xcode 9.2 works well for Mac OS Sierra (10.12.6). I installed it today (3rd Feb 2020). 3: For OS Sierra/10.12.6 you need Xcode-8.3 from below link. MacOS 10.12 SDK was first introduced in Xcode 8.0. The last macOS 10.12 SDK was macOS 10.12.4 SDK which was released with Xcode 8.3. Xcode 8.3 saw three bug fix releases with the last one being Xcode 8.3.3. You'll need to download both the desired version of Xcode, and the compatible release of macOS which can run the said Xcode release.
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.
Xcode IDE contain Command-Line utilities. But separate Command-Line installer cause errors for use by Homebrew, Python, and other development tools
- What Has Been Installed?
- Xcode Version
- Xcode IDE install from Terminal
- B) Initial IDE install using web App Store
This tutorial describes the installation and usage of Apple’s Xcode set of utilities for macOS developers.
Xcode is Apple’s free app for developing custom programs for all Apple devices (macOS, iPhone, iPad, Apple Watch). Increasingly, Machine Learning developers are using the Swift language.
Since the Apple Store only handles individual .app files, other mechanisms are needed to install additional programs needed as a pre-requisite by Homebrew, Python, and other development programs.
BTW Xcode only works on macOS. There is no Windows PC version.
About Xcode
PROTIP: Skip Apple’s websites and App. Click here for install instructions (below).
Otherwise, read on for a run-around.
- Use an internet browser to view Apple’s Xcode marketing page at:Xcode “includes everything you need to create amazing apps for all Apple platforms. Now Xcode and Instruments look great in the new Dark Mode on macOS Mojave. The source code editor lets you transform or refactor code more easily, see source control changes alongside the related line, and quickly get details on upstream code differences. You can build your own instrument with custom visualization and data analysis. Swift compiles software more quickly, helps you deliver faster apps, and generates even smaller binaries. Test suites complete many times faster, working with a team is simpler and more secure, and much more.”.BTW the “Apple platforms” include MacOS, iPhone, iPad, Apple TV, and Apple Watch.
Xcode does not come with macOS because of its large size and because many users of macOS don’t need it to do software development.
Developers who use another IDE (such as Visual Studio, Eclipse, etc.) would only need to install Xcode’s command line utilities for the GCC compiler Python needs to build code.
PROTIP: Newer versions of Xcode installer also installs a Git client.
Overlapping installers
Imagine a Venn diagram of overlapping circles:
- The Xcode IDE, which can be installed on a Terminal command line interface (CLI) or
- downloaded as a package from the App Store.
Either way, Xcode contains:
- Command Line Utilities which can be installed separately on a Terminal command line session.
PROTIP: Xcode IDE cannot be installed if Command Utilities has already been installed.
However, you can switch:
So choose which one you want installed.
What Has Been Installed?
- In a Terminal window, find out what has been installed:That’s the same command as:If the Xcode-select command is not found, choose to eitherinstall Command Line Tools or install the full Xcode IDE.You have Command Line Tools installed and not the full Xcode if you see the path where CommandLineTools are installed:If all you need is Command Line Tools, you’re good to go.Alternately, if the full Xcode was installed, you would instead see:
- Get a list of its folders if Xcode IDE was installed:The response would be:
Delete first
- PROTIP: If you want the full Xcode IDE when you have the Command Line Tools installed, first uninstall Command Line Tools, then install the full Xcode IDE.
More version information
Xcode Version
- From within a Terminal, type:If Command Line Tools was installed, you would see:If Xcode is installed, you would get a version code that should match up with the Build Number on the Apple web page:
- For a more precise version number and other info (macOS Mavericks version and up):A sample response, at time of writing:The previous command was constructed based on a search of tools package names:The response:
- Get the version of GCC installed:If Xcode was installed, you would see (at time of writing):Previously, it was instead:If Command Line Utilities is installed, you would see (at time of writing):
- Identify the path where the make utility Java uses:a. If Xcode is installed, the response is:b. If Command Line Utilities is installed, the response is:c. If no Xcode is installed:
Swift version
- Get the version of the Swift program used to develop iOS mobile apps:Sample response at time of this writing:If jamf installed Xcode, you’ll also see:The above appears regardless of whether Command Line Utilities or Xcode is installed.From here, uninstall and install Command Line Tools or install the full Xcode IDE.
UnInstall Command Line Tools
PROTIP: This is also how you upgrade Command Line Tools. - Go to the parent folder where Command Line Tools is installed:
- Get a list of its folders:If Command Line Tools were installed, the response would be :
- Remove all files in that folder, which requires a password for elevated permissions to get all the files:The response is a lot of files removed (to the Trash).Now you can choose to eitherinstall Command Line Tools or install the full Xcode IDE.
Install Command Line Utilities only
See https://developer.apple.com/library/archive/technotes/tn2339/_index.html and http://osxdaily.com/2014/02/12/install-command-line-tools-mac-os-x - To install the whole Xcode IDE:You should see this pop up:
