Build error for Swift 4 on Xcode 9.2

/Users/jianli/iosApp/examples/myTest/SwiftSSDPExample/Carthage/Checkouts/SwiftSSDP/SwiftSSDP/SSDPResponse.swift:174:43: error: 'rangeAt' has been renamed to 'range(at:)'
let capturedRange = match.rangeAt(1)
^~~~~~~
range at:
Foundation.NSTextCheckingResult:25:15: note: 'rangeAt' was obsoleted in Swift 4
open func rangeAt(_ idx: Int) -> NSRange

Changed to let capturedRange = match.range(at: 1), then build successful.

And there is the same error when directly build SwiftSSDP.

Thanks a lot. Your project is really great.

How did you get it to work? When I applied the fix, Carthage complains about range(at:) only available in Swift 4... Is there a way to make it happy?
