Swift Package Manager - UIKit Dependency

Question

I have a Package.swift in my project like:

import PackageDescription

let package = Package(
    name: "ProjectName",
        dependencies: [
           .Package(url: "https://github.com/intellum/neeman.git", majorVersion: 0)
        ]
 )

When I run swift build I get errors like…

/project/Packages/WebViewController.swift:1:8: error: no such module 'UIKit'
import UIKit
       ^

Where should I tell the swift package manager where to find UIKit?

Answer 1

The Swift Package Manager builds executables to run on OS X (or Linux); UIKit is a framework in iOS and won't be accessible.

It may be iOS, tvOS and others become accessible as Swift Package Manager evolves.

Right, now we only compile for the host platform (OS X or Linux, currently). Among other things, we currently have no knowledge (or options to choose) what SDK or architecture you are targeting. We also have no mechanisms for specifying what platforms targets are compatible with in the manifest.

Answer 2

Currently Swift Package Manager has full Xcode support. I was able to get around this error by specifying in my Package.swift manifest that the platform was iOS.

let package = Package(
    name: "MyPackage",
    platforms: [
        .iOS(.v8)
    ],

Then you can open the Package.swift file in Xcode and it will just work.
