CVPixelBuffer not supported

[cyberhenoch]

Hi there! Firstly thanks for sharing this concept. It may be very useful and much more convenient than exporting framework from xcode. 👍

I have an issue though with passing CVPixelBuffer parameter to function. A minimal example:

import Foundation
import CoreVideo
import CoreImage

@objc(HelloWorld)
public class HelloWorld : NSObject {
    @objc(helloWorldWithPixelBuffer:)
    public class func helloWorld(pixelBuffer: CVPixelBuffer) -> String {
        return "HeLLo WorLd!"
    }
}

During sync with gradle I get:

Task :shared:cinteropSwiftIosArm64
Warning: Failed to generate cinterop for :shared:cinteropSwiftIosArm64: Process 'command '/Applications/Android Studio Preview 3.app/Contents/jbr/Contents/Home/bin/java'' finished with non-zero exit value 1

generated header is:

SWIFT_CLASS_NAMED("HelloWorld")
@interface HelloWorld : NSObject
+ (NSString * _Nonnull)helloWorldWithPixelBuffer:(**[ERROR POINTS HERE]**CVPixelBufferRef _Nonnull)pixelBuffer SWIFT_WARN_UNUSED_RESULT;
- (nonnull instancetype)init OBJC_DESIGNATED_INITIALIZER;
@end

When I change CVPixelBuffer to String it works fine.
