  1. 3.1 SWIFT PACKAGE MANAGER

  2. SWIFTPM PACKAGE MANAGER GOALS The Swift Package Manager is a

    tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies. The Package Manager is included in Swift 3.0 and above. The Big Vision: ‣ https://github.com/apple/swift-package-manager/blob/master/Documentation/ PackageManagerCommunityProposal.md 2
  3. SWIFTPM WHAT IT DOES TODAY ‣ Collect dependencies based on

    a manifest ‣ Resolve dependencies ‣ Suggest how to install related dependencies with brew or apt ‣ swift build, test, and package commands ‣ Build & link C and Swift code ‣ Generate xcode project file ‣ Pass through CLI flags to llbuild/clang layers 3
  4. SWIFTPM CONSTRAINTS AND LIMITS (SWIFT 3.1) ‣ Only git for

    source control ‣ minimal fork support ‣ Limited ability to have configurable “C” builds ‣ c++ support starting in dev ‣ Minimal integration with Xcode ‣ project generation only ‣ No integration with Objective-C/IOS ‣ external package support coming in swift 4 4
  5. SWIFTPM INFLUENCES Cocoapods Carthage Javascript’s NPM Rust’s Cargo … and

    really quite a number of others - PyPi, CPAN, etc. 5
  6. SWIFTPM GETTING STARTED ▸ swift package init --type=executable ▸ .gitignore

    ▸ Package.swift ▸ Sources/main.swift ▸ Tests 6
  7. SWIFTPM DEMO & EXAMPLES ▸ (more complex) ▸ Vapor ▸

    https://github.com/vapor/vapor ▸ (simpler) ▸ Guaka ▸ https://github.com/oarrabi/Guaka 7
  8. SWIFTPM C LIBRARY EXAMPLES ▸ YAMS https://github.com/jpsim/Yams ▸ Sources/CYaml ▸

    Sources/Yams ▸ Kitura's CCurl https://github.com/IBM-Swift/CCurl ▸ Brew/apt of underlying library ▸ module.modulemap 8
