I need to use the ios-charts module coded in Swift in a TiUIView, but when I try to generate the native appcelerator module I can't because it generates a static library and Swift can't be used to do that, only is used to generate dynamics libraries.
You've hit a sensitive issue here. Since the Titanium module is a static library it cannot contain swift code (that's xCode limitation not titanium). You can see my question about it here: Swift in Objective-c project: not supported for static libraries
What you would have to do is wrap your swift code in a framework and link that framework in your Titanium module project.
