Swift Package Manager or Let’s make dependency manager great, Finally!
Kostiantyn Koval @Agens AS • Swift from day 1 •
Swift Hight Performance • Swift Package Manager • @KostiaKoval
pod install
How it used to be ! ... • Static libraries
lib.a • Copied source • Subproject + Workspace • Submodules
The problems ! • Closed code / Precompiled • Hard
to discover • No versioning • Duplicate Symbols a->c, b->c App ->(a, b) Duplicate 'c'
CocoaPods - Easy • Centralized • Podspec • Static Libs
+ Frameworks • Modifies Xcode projects + workspace Res: Workspace
Carthage - Simple • Decentralized • No Podspec • Git
+ Xcode • Frameworks Res: Frameworks
Happy
Problems • Not integrated with ! • Xcode private API
and Format • Custom scripts • Limited
SwiftPM
Why it was built? iOS Linux
SwiftPM Cross platform, Convention approach, Decentralized is a tool to
automate the process of downloading, compiling, and linking dependencies. — Swift .org
SwiftPM Fetch Build Test swift package swift build swift test
"swift package" clean Delete build artifacts describe Describe the current
package dump-package Print parsed Package.swift as JSON fetch Fetch package dependencies generate-xcodeproj Generates an Xcode project init Initialize a new package reset Reset the complete cache/build directory show-dependencies Print the resolved dependency graph update Update package dependencies
What is a Swift Package ?
What is a Swift Package ? Package.swift import PackageDescription let
package = Package( name: "Empty" )
What is a Swift Package ? • Swift, C, C++,
Objective-C, Objective-C++ One language per module • library (static, dynamic), executable, system-module
Package Convention Source in - /Sources Tests in - /Tests
Executable - main.swift Lib - SomeLib.swift C headers - /include/Baz.h

Package + Git = ! • Step N1: git init,

no Step N2 !

But is it ready for Production and big Projects?
SwiftPM uses SwiftPM to "build and test" SwiftPM
SwiftPM • 19 Modules • 31 Targets • 13 Test
Modules • A lot of Code an Tests
None
It does handle the Scale
The iOS !
Does the SwiftPM solves the issue? YES!, kind off, it
will. ! • Painless config • Right Xcode project integration • Full Build & Tests control • Open Source • Many, many more ...
swift build The new -
