Mandatory use_frameworks! in podfile

[kleytonlopes]

Some projects may not use use_frameworks! because of the limitations of its dependencies. When I remove use-frameworks!, the project does not compile:
/MapboxGeocoder.swift/Swift Compatibility Header/MapboxGeocoder-Swift.h:171:9: error: 'MapboxGeocoder/MapboxGeocoder.h' file not found
#import <MapboxGeocoder/MapboxGeocoder.h>
^
:0: error: could not build Objective-C module 'MapboxGeocoder'

Why the import is not: <MapboxGeocoder.swift/MapboxGeocoder.h>?
