Importing Internet-based SwiftPM packages to your Xcode Playground — Erica Sadun

I’ve been kicking the wheels on Xcode 12 and its means to make use of frameworks and packages with playgrounds. Up till now, I’ve solely been capable of import packages which are both downloaded or developed domestically on my dwelling system. Nonetheless, a variety of the packages I need to work with are hosted from GitHub.

I made a decision to comply with a hunch and see if I might import my dependency by means of a neighborhood Forwarding package deal after which use that code. Lengthy story brief: I might.

Right here’s my playground, efficiently working.

The RuntimeImplementation is asserted in a GitHub-hosted package deal referred to as Swift-Basic-Utility:

What I did to make this work was that I created what I referred to as a Forwarding Utility, whose sole job is to create a shell package deal that is determined by the distant package deal and forwards it to the playground. It appears like this. It’s a single file referred to as “Forwarding.swift” (no, the title is in no way magic.) in Sources/. I exploit @_exported to ahead the import.

/*
 
 Use this to ahead web-based dependencies to Swift Pkg
 
 */

@_exported import GeneralUtility

Its Bundle.swift installs the dependency:

    dependencies: [ .package(url: "https://github.com/erica/Swift-General-Utility", .exact("0.0.4")), ],
    targets: [
        .target(
            name: "ForwardingUtility",
            dependencies: [ .product(name: "GeneralUtility"), ],
            path: "Sources/"
        ),
    ],

And that’s just about all that there’s to it, apart from (as I discussed in my different put up about tips on how to use SwiftPM packages in playground workspaces) that you might have to stop and re-open the primary beta earlier than you’ll be able to import the forwarding.

Let me know something that I tousled. But in addition let me know if this was useful to you!
