Here are Swift 3 details that is obtained from [here](http://swift-arm.ddns.net/job/Swift-3.0-ARMv7-ubuntu1410/29/artifact/swift-3.0-2016-11-03-armv7-ubuntu14.04.tar.gz):

When the package in the attached zip is built using `swift build`, the following compilation error is seen:

root@20115a3ec356:/tmp/iot.publisher# swift build
Compile Swift Module 'iot_publisher' (3 sources)
/tmp/iot.publisher/Sources/Connection.swift:21:9: error: type 'Stream' has no member 'getStreamsToHost'
        Stream.getStreamsToHost(withName: address, port: port, inputStream: &inputStream, outputStream: &outputStream)
        ^~~~~~ ~~~~~~~~~~~~~~~~
<unknown>:0: error: build had 1 command failures
error: exit(1): /tmp/swift-3.0/usr/bin/swift-build-tool -f /tmp/iot.publisher/.build/debug.yaml

The same package compiles and runs fine on macOS under Swift 3. The attached Dockerfile shows the base OS image as well as all the libraries that were installed.

For some reason I could not delete the above comment. It's work-in-progress and not ready, since we don't have `AutoreleasingUnsafeMutablePointer` on Linux – will probably just change the signature to return a tuple instead.
