title: Import Swift framework to Obj-C
body: <p>I have framework that written in Swift like this.</p>
  <pre><code>import Foundation
  import WebKit
  import ObjectiveC
  
  public extension WKWebView {
  
      public func someFunc(_ completionHandler:@escaping (_ capturedImage: UIImage?) -&gt; Void) {
          //Some code
      }
  }
  </code></pre>
  <p>When I build the frameworks and import to Objective-C code that use Cocoapods for Dependency Manager. I Can't call above someFunc function. The error said this:</p>
  <blockquote>
  <p>No visible @interface for 'WKWebView' declares the selector 'someFunc'</p>
  </blockquote>
  <p>This is how I implement Swift framework in Objective-C:</p>
  <pre><code>#import &lt;Foundation/Foundation.h&gt;
  #import &lt;ProjectName-umbrella.h&gt;
  @implementation CapturerDefault
  - (void)captureWebViewScreenWith:(UIView *)containerView
              andCompletionHandler:(void (^)(UIImage *))completion {
      WKWebView *webView = [self findWebViewInViewController:containerView];
      
      [webView someFunc: resultImage] //The error show here.
      }
  }
  </code></pre>
  <p>What is wrong? Did i miss something?</p>
