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

I’ve been kicking the wheels on Xcode 12 and its potential to make use of frameworks and packages with playgrounds. Up till now, I’ve solely been capable of import packages which might be both downloaded or developed domestically on my house system. Nevertheless, numerous the packages I wish to work with are hosted from GitHub.

I made a decision to comply with a hunch and see if I may import my dependency by way of an area Forwarding bundle after which use that code. Lengthy story brief: I may.

Right here’s my playground, efficiently working.

The RuntimeImplementation is said in a GitHub-hosted bundle referred to as Swift-Normal-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 bundle that is determined by the distant bundle and forwards it to the playground. It seems 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, aside from (as I discussed in my different publish about the way to use SwiftPM packages in playground workspaces) that you could have to stop and re-open the primary beta earlier than you may import the forwarding.

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