I haven't done any work building mobile apps with Rails, but I followed the very informative RailsConf demo from Sam Stephenson on Turbolinks 5 as a tool for building cross platform Apps with rails, Turbolinks 5 Demo and it looks great. The only part I can't replicate is how to get the "Turbolinks.framework" file that needs to be embedded in the iOS app shell.
The documentation at github's Turbolinks-ios page refers to a number of package managers for iOS (Carthage and CocoaPods) with which I am unfamiliar, or alternatively suggests "building Turbolinks manually and linking to my project." I think he demos the linking part, but no idea how to "build Turbolinks manually". Can someone give me a clue?
