Issue when compiling under Swift 4?

[TempaGoGo]

Guys, When I try to complete a project under Swift 4, using S3SignerAWS, Xcode suggests a code change in the following function:

internal func canonicalHeaders(
	headers: [String: String])
	-> String
{
		let headerList = Array(headers.keys)
			.map { "\($0.lowercased()):\(headers[$0]!)" }
			.filter { $0 != "authorization" }
			.sorted { $0.localizedCompare($1) == ComparisonResult.orderedAscending }
			.joined(separator: "\n")
			.appending("\n")
		
		return headerList

}

to

internal func canonicalHeaders(
headers: [String: String])
-> String
{
let headerList = Array(headers.keys)
.map { "($0.lowercased()):(headers[$0]!)" }
.filter { $0 != "authorization" }
.sorted { $0.0.localizedCompare($0.1) == ComparisonResult.orderedAscending }
.joined(separator: "\n")
.appending("\n")

		return headerList
}

This then causes other syntax issues.

Kind regards, Phil

Hey Phil,

Just updated project for swift 4 compatibility. You should be good to go.
