Product required by package not found. Did you mean `.product(name: "Foo", package: "bar")`?

[alicerunsonfedora]

Is it reproducible with SwiftPM command-line tools: swift build, swift test, swift package etc?

• Confirmed reproduction steps with SwiftPM CLI. The description text must include reproduction steps with either of command-line SwiftPM commands, swift build, swift test, swift package etc.

Description

In my livestream today, I attempted to expose a product (CPlaydate) from a dependent package (PlaydateKit):

products: [
        .library(name: "PlaydateKit", targets: ["PlaydateKit"]),
        .library(name: "CPlaydate", targets: ["CPlaydate"])],

However, upon doing so, I ended up receiving this odd error:

$ swift build -c release
error: 'packageresolved': product 'CPlaydate' required by package 'packageresolved' target 'PackageResolved' not found in package 'playdatekit'. Did you mean '.product(name: "CPlaydate", package: "playdatekit")'?
error: ExitCode(rawValue: 1)

Even though my code was defined as:

.target(
            name: "PackageResolved",
            dependencies: [
                .product(name: "CPlaydate", package: "PlaydateKit"),
                .product(name: "PlaydateKit", package: "PlaydateKit"),
                "Charolette",
                "KDL"
            ],
            swiftSettings: swiftSettingsSimulator
        ),

@rauhul also noticed this error on the livestream.

Expected behavior

The command swift build -c release works as expected.

Actual behavior

However, upon doing so, I ended up receiving this odd error:

$ swift build -c release
error: 'packageresolved': product 'CPlaydate' required by package 'packageresolved' target 'PackageResolved' not found in package 'playdatekit'. Did you mean '.product(name: "CPlaydate", package: "playdatekit")'?
error: ExitCode(rawValue: 1)
