Am trying to convert a custom label class which is in objective c to swift. Post making the conversion in same .m and renamed it to .swift file. custom label in xib not linked to .swift file. we need to visit each xib file and update the class name manually and select inherit module from target in attribute inspector to link xib. since we use custom label in over 500 places is there any other way to link this.
See this recent post.
I have gone through that post as well but there are no changes in xib files.
No idea then. 
Long term - would recommend getting rid of xib's. And UIKit
