Using Swift Package Manager with iOS

Step 1:

File > New > Project...

Step 2:

Create a Package.swift file in your root project directory, add dependencies, then run swift package fetch on the command line in the same directory. We’re not going to run swift build because it will just complain.

// Protocol for a type that supports a fromRaw(Int) conversion
// (such as "enum Foo: Int { ... }")
protocol ConvertibleFromRawInt {
    class func fromRaw(raw: Int) -> Self?
}

// Note: Tried to use Swift's standard RawRepresentable protocol rather
// than ConvertibleFromRawInt, but couldn't get it to compile.
// Don't know whether it is a Swift bug or something I was doing wrong.
