Cannot compile SwiftAA with Swift4

[alex-vasenin]

Even with SWIFT_VERSION=3.2, due to the changes in Swift Standard Library, Xcode 9 says .../SwiftAA/Angles.swift:96:15: Type 'ArcMinute' does not conform to protocol 'Numeric' for all NumericTypes

Hm... I haven't opened Xcode9 yet (but I have it installed!). Too busy elsewhere. I'll have a look!

Hm, Xcode requires to implement these stubs (here for Degree but similar for others):

public static func *(lhs: Degree, rhs: Degree) -> Degree {
    <#code#>
}

public static func *=(lhs: inout Degree, rhs: Degree) {
    <#code#>
}

No idea how to deal with it right now.

I just ran into this as well. I'd be down to help out. I started along the path described above but ran into some issues with public typealias Magnitude = <#type#> in the Xcode suggestion when I hit the Fixit button. I'll have to look at it a bit later.

Hm, I wish we could finish milestone 2.0 before migrating to Swift4...

I renamed the issue, because it is formally possible to compile current SwiftAA with Xcode9. But we have to work on Swift4 (milestone 3.0)

This is now done since quite a while. Closing.

Thank you!
