Building requires Swift 4.2

[LoryB]

Swift 4.2 is only available on Xcode 10 beta... Is there a way to build the console application with the previous Swift version (4.1)?
Otherwise you should write "Xcode 10 beta required" on instructions
You did an amazing job ;)
P.S. Form application will be better for users in the future imo :)

Please edit Package.swift file. You have to change this line:

swift-tools-version:4.2

to that one:

swift-tools-version:4.1

It's only information for your Swift console tool. The source code is compatible with Swift 4.1 and 4.2.
