Hi. Replia enables the import of data from Sketch.
Replia is a Mac App which generates iOS app source code (Obj-C/swift/Storyboard) from the Photoshop source file of an appís design data.
We make Sketch plugins to export data for Replia, and now we've released a free demo version of Replia. The demo version of Replia limits the export of source code to show a small-scaled view. Try it.
