Add the package to Your SwiftPM package dependencies:
.package(
name: "swift-generic-color",
url: "https://github.com/capturecontext/swift-generic-color.git",
.upToNextMinor(from: "0.5.0")
)
then add GenericColor
dependency to your target
.product(
name: "GenericColor",
package: "GenericColor"
)
