[BuildPlan] Moved -Xcxx flags to the end of the chain of arguments (#1380) * [BuildPlan] In reference to SR-6164, moved -Xcxx flags to the end of the chain of arguments. - https://bugs.swift.org/browse/SR-6164 * Commented the constraints for argument ordering to allow user overrides of -Xswiftc, -Xlinker, -Xcc and -Xcxx. - https://bugs.swift.org/browse/SR-6164
The Swift Package Manager is a tool for managing distribution of source code, aimed at making it easy to share your code and reuse others’ code. The tool directly addresses the challenges of compiling and linking Swift packages, managing dependencies, versioning, and supporting flexible distribution and collaboration models.
We’ve designed the system to make it easy to share packages on services like GitHub, but packages are also great for private personal development, sharing code within a team, or at any other granularity.
Note that at this time the Package Manager has no support for iOS, watchOS, or tvOS platforms.
To learn about the policies and best practices that govern contributions to the Swift project, please read the Contributor Guide.
If you are interested in contributing, please read the Community Proposal, which provides some context for decisions made in the current implementation and offers direction for the development of future features.
Instructions for setting up the development environment are available here.
The Swift package manager uses llbuild as the underlying build system for compiling source files. It is also open source and part of the Swift project.
The package manager’s system requirements are the same as those for Swift with the caveat that the package manager requires Git at runtime as well as build-time.
The Swift Package Manager is included in Xcode 8.0 and all subsequent releases.
The package manager is also available for other platforms as part of all Snapshots available at swift.org, including snapshots for the latest versions built from
master. For installation instructions for downloaded snapshots, please see the Getting Started section of swift.org.
You can verify your installation by typing
swift package --version in a terminal:
$ swift package --version Apple Swift Package Manager - ...
/usr/bin/swift is just a stub that forwards invocations to the active toolchain. Thus when you call
swift build it will use the swift defined by your
TOOLCHAINS environment variable. This can be used to easily switch between the default tools, and a development snapshot:
$ xcrun --find swift /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift $ swift --version Apple Swift version 3.0 $ export TOOLCHAINS=swift $ xcrun --find swift /Library/Developer/Toolchains/swift-latest.xctoolchain/usr/bin/swift $ swift --version Swift version 3.0-dev
To use a specific toolchain you can set
TOOLCHAINS to the
CFBundleIdentifier in an
SWIFT_EXEC environment variable specifies the
swiftc executable path used by
swift package. If it is not set, the package manager will try to locate it:
swift-package's parent directory.
xcrun --find swiftc.

For additional documentation on developing the Swift Package Manager itself, see Documentation/Development.
If you have any trouble with the package manager, help is available. We recommend:
If you’re not comfortable sharing your question with the list, contact details for the code owners can be found in CODE_OWNERS.txt; however, the mailing list is usually the best place to go for help.
