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.
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.
This page describes how to download and install the analyzer. Oncethe analyzer is installed, follow the instructions on using scan-build toget started analyzing your code.
Packaged Builds (Mac OS X)
Semi-regular pre-built binaries of the analyzer are available on MacOS X. These are built to run on OS X 10.7 and later.
Builds are released frequently. Often the differences between buildnumbers being a few bug fixes or minor feature improvements. When usingthe analyzer, we recommend that you check back here occasionally for newbuilds, especially if the build you are using is more than a coupleweeks old.
The latest build is:
Packaged builds for other platforms may eventually be provided, butwe need volunteers who are willing to help provide such regular builds.If you wish to help contribute regular builds of the analyzer on otherplatforms, please email the ClangDevelopers' mailing list.
Using Packaged Builds
To use a package build, simply unpack it anywhere. If the buildarchive has the name checker-XXX.tar.bz2 then thearchive will expand to a directory called checker-XXX.You do not need to place this directory or the contents of thisdirectory in any special place. Uninstalling the analyzer is as simpleas deleting this directory.
Apple Mac Os X Download
Most of the files in the checker-XXX directory willbe supporting files for the analyzer that you can simply ignore. Mostusers will only care about two files, which are located at the top ofthe checker-XXX directory:
scan-build: scan-build is the high-level command line utility for running the analyzer
scan-view: scan-view a companion comannd lineutility to scan-build, scan-view is used to viewanalysis results generated by scan-build. There is an optionthat one can pass to scan-build to cause scan-view torun as soon as it the analysis of a build completes
Mac Clang Version
Running scan-build
For specific details on using scan-build, please seescan-build's documentation.
To run scan-build, either add thechecker-XXX directory to your path or specify a completepath for scan-build when running it. It is also possible to usea symbolic link to scan-build, such one located in a directoryin your path. When scan-build runs it will automaticallydetermine where to find its accompanying files.
Other Platforms (Building the Analyzer from Source)
Mac Os X Download Dmg
For other platforms, you must build Clang and LLVM manually. To doso, please follow the instructions for building Clang fromsource code.
Once the Clang is built, you need to add the following to your path:
Clang Mac Os X Download
The location of the clang binary.
For example, if you built a Debug+Asserts build of LLVM/Clang (thedefault), the resultant clang binary will be in $(OBJDIR)/Debug+Asserts/bin(where $(OBJDIR) is often the same as the root source directory). Youcan also do make install to install the LLVM/Clang libraries andbinaries to the installation directory of your choice (specified when you runconfigure).
The locations of the scan-build and scan-viewprograms.
These are installed via make install into the bin directorywhen clang is built.
