Accessing UIWindow from AppDelegate.swift in Objective-C file

Question

I am working on swift project where I need to use my old Objective-C code.

I did managed to create -Bridge-Header.h file and it works for me.

now in my Objective-C code I need to refer UIWindow from AppDelegate.swift,

Can any one has done this before?

Please guide me!

First to access the Swift classes in ObjC ,you could import the compiler generated header file to expose those files to ObjC. It would be like ProductModuleName-Swift.h.(This file doesn't really exists to see,but Xcode will automatically create it for you)

#import "YourProductName-Swift.h"

Then you can access the window property in the app delegate from the ObjC file like

AppDelegate *delegate = [[UIApplication sharedApplication]delegate]; UIWindow *window = delegate.window;

how can i import the compiler generated header file?

Like importing any other file #import "YourProductName-Swift.h". YourProductName will be same as app target name

i did import "#import "MyProjectName-Swift.h" but it shows me an error "file not found".
