Swift 4: var running error

[marc-medley]

FYI: Swift 4 produces a compile time error for

var running: Bool { @objc(isRunning) get }

ERROR: Unavailable var 'running' was used to satisfy a requirement of protocol 'SBApplicationProtocol'

Here is one possible alternative that compiles and runs OK for me in Xcode 9, Swift 4 beta 6:

@objc optional var isRunning: Bool { get }

Here's another alternative, without using @objc optional, which is also currently running OK for me on macOS 10.12, Xcode 9 beta 6, Swift 4:

@objc
public protocol SBApplicationProtocol: SBObjectProtocol {
    func activate()
    var delegate: SBApplicationDelegate! { get set }
    var isRunning: Bool { get }
}

@marc-medley Thanks for the heads-up. I've yet to look at a Swift 4 update to SwiftScripting. I'll keep this in mind.

I just pushed an update for Swift 4. Please give it a try and see if it resolves this issue.
