Can I use an Objectice-C class in my Swift framework library?

I have created a Swift Framework that I use in multiple projects. There is an Objectivce-C class that I would like to use in that is difficult to port in straight Swift. Lets say that class is SFTest

#import <CommonCrypto/CommonCrypto.h>
@interface SFTest {
} 
+ (NString *)myMethod(NSString *data);
@end
@implementation SFTest
+ (NString *)myMethod(NSString *data) {
    // does some crypto stuff
    retu cryptoData;
}
@end

Can I somehow use this in my Swift framework project? As far as my research goes, Swift frameworks can't generate bridging headers.
