Issues building the latest version

[SirWellington]

Trying to build this using Carthage on XCode 9.4.1.

Getting the following errors:

public typealias LayoutAttribute = NSLayoutConstraint.Attribute
                                   ~~~~~~~~~~~~~~~~~~ ^

Did you mean to use NSLayoutAttribute.

For anyone still having trouble with this: NSLayoutAttribute was renamed to NSLayoutConstraint.Attribute in Swift 4.2.

I opened a PR to add swift_version = 4.2 to the podspec, which will remove the requirement that Cartography is integrated into a target that also uses 4.2 (for those using Cocoapods, at least).
