-

when take .dae file , file, info on osx's finder see 

kind: digital asset exchange (dae)

.rtfd shows 

kind: rich text document attachments

but osx. now, how discover kind of file on ios nsurl of file?

there may other ways, 1 way use uniform type identifier (uti) services provided mobilecoreservices.

import mobilecoreservices

just description associated extension's uti:

if let uti = uttypecreatepreferredidentifierfortag(kuttagclassfilenameextension, pathextension, nil)?.takeretainedvalue(), let description = uttypecopydescription(uti)?.takeretainedvalue() {     print(description) }

see how system identifies type of content in file in file system programming guide.
