Specify minimum macOS version for Swift Package Manager with Swift 5

In order to have some code compile with SwiftPM, without adding #if available, I'm building the project with the following parameters:

swift build -Xswiftc "-target" -Xswiftc "x86_64-apple-macosx10.11"

Swift Package Manager also works with Xcode .xcconfig files, but only when generating an Xcode project.

Is there an easy way in Swift 5 to specify the minimum version of macOS when building from the command line with swift build?

Compiler error example:

error: 'archivedData(withRootObject:)' is only available on OS X 10.11 or newer
        let data = NSKeyedArchiver.archivedData(withRootObject: value)

Alex 's answer is useful

But when i try to run an old project, still error. The file header needs to be modified to

// swift-tools-version:5.0

'platforms' is affective after 5.0

let package = Package(
    name: "NAME",
    platforms: [
        .macOS(.v10_11)
    ],
    products: [
        .library(name: "NAME", targets: ["NAME"]),
    ],
    targets: [
        .target(name: "NAME"),
    ]
)

One way to do this is with Deployment Settings in SPM.
