Accessing Objective-C block from Swift

Question

I have this Objective-C code in FileManagerHelper:

+(void)getMyVideoObject:(NSString *)videoId completion:(void (^)(MyVideoObject *myVideoObject, NSError *error)) completionBlock
{

}

For calling from Objective-C:

 [FileManagerHelper getMyVideoObject:videoId completion:^(MyVideoObject *myVideoObject, NSError *error) {

}];

But how do I call this getMyVideoObject from Swift?

FileManagerHelper.getMyVideoObject( .....?

Yes, when you import header file into bridge header then Swift will generate Swift version of function signature and you can call it like that. — andykkt

1) Add into your bridging header (-Bridging-Header.h file generated when you add .swift file to Objective-C project)

#import "FileManagerHelper.h"

2) In swift code use the following call

FileManagerHelper.getMyVideoObject("id") { (video, error) in

}
