Could not build Objective-C module '_SwiftUIKitOverlayShims'

Hi,


I am developing an application using Swift 3.3 and it is working fine with XCode 8.3.3 version. But I am getting following error with XCode 9.1



<module-includes>:1:9: note: in file included from <module-includes>:1:
#import "UIKitOverlayShims.h"
^
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/shims/UIKitOverlayShims.h:24:11: error: use of undeclared identifier 'UIFocusSystem'
return [UIFocusSystem environment:environment containsEnvironment:otherEnvironment];
^
<unknown>:0: error: could not build Objective-C module '_SwiftUIKitOverlayShims'



I tried Build Clean and deleted Derived folder. But no luck.


Please help.
