Can't build with Xcode 8 Beta 6

[randyhill]

I'm trying to use Just in an iOS 10 message extension. Due to various issues, Cocoapods isn't working for me, so I've tried dropping in Just.swift, but I get a whole mess of compile errors, some I don't feel confident about fixing.

Has Swift 3 syntax changed since your last build?

One example

public lazy var headers:CaseInsensitiveDictionary<String,String> = {
    return CaseInsensitiveDictionary<String,String>(dictionary: (self.response as? HTTPURLResponse)?.allHeaderFields as? [String:String] ?? [:])
}()

produces the error Expression type '[String : String]? is ambiguous without more context, on the return line.

This works...
public lazy var headers:CaseInsensitiveDictionary<String,String> = {
if let httpResponse = self.response as? HTTPURLResponse {
let headerFieldsDict = httpResponse.allHeaderFields as NSDictionary? as? [String:String]
return CaseInsensitiveDictionary<String,String>(dictionary: headerFieldsDict ?? [:])
}
return [:]
}()

I have fixed all the other compile errors, will try to check in my version to you after I see if it works.
