#Swift share extension tutorial code#
Rather than using a data format, like JSON or XML, Swift package manifest files are written using actual Swift code - with a Package instance representing the declaration of the package.Īs an example, let’s say that we’re working on a todo list app, and that we want to create a TodoKit package for all of our core logic that’s shared across the app - including things like our database layer, our model code, and so on. The contents of a package is declared using a Package.swift manifest file, which is placed in the root directory of each package. Packages can either be public libraries that are shared using services like GitHub, or internal tools and frameworks that are only shared within a small number of projects. The anatomy of a Swift packageĪ Swift Package is essentially a group of Swift source files that are compiled together to form a Module - which can then be shared and imported into other projects as one unit. However, while the server-side Swift community quickly embraced the Swift Package Manager as the go-to tool for managing dependencies when building server applications, it’s taken quite a while for it to become fully integrated into the rest of Apple’s developer toolchains.īut now, starting with Xcode 11, the Swift Package Manager is finally becoming a true first class citizen within Apple’s suite of developer tools - so this week, let’s take a look at how it can be used to manage a project’s various dependencies - both internal and external ones.
While it wasn’t the first dependency manager for Swift projects, it was the first that was officially provided and supported by Apple, which many developers saw as really good news. When Swift was open sourced at the end of 2015, one of the most surprising and interesting new projects that was introduced along with it, was the Swift Package Manager.
