我必须将目标C代码转换为swift3.0，尝试进行在线转换时出现错误

Question

NSURL *contentURL = [[NSURL alloc] initWithString: @"http://en.wikipedia.org/wiki/Facebook"];

NSURL *imageURL = [NSURL URLWithString:@"http://upload.wikimedia.org/wikipedia/commons/thumb/9/95/Facebook_Headquarters_Menlo_Park.jpg/2880px-Facebook_Headquarters_Menlo_Park.jpg"];

button.shareContent = [[FBSDKShareLinkContent alloc]

                                       ref: @"myRefId"];

Answer 1

I had no problem converting it online (compiler only complains that I haven't defined FBSDKShareLinkContent:

func dummy(button: UIButton) {
    //  Converted with Swiftify v1.0.6276 - https://objectivec2swift.com/
    var contentURL = URL(string: "http://en.wikipedia.org/wiki/Facebook")
    var imageURL = URL(string: "http://upload.wikimedia.org/wikipedia/commons/thumb/9/95/Facebook_Headquarters_Menlo_Park.jpg/2880px-Facebook_Headquarters_Menlo_Park.jpg")
    button.shareContent = FBSDKShareLinkContent(contentURL: contentURL, contentTitle: "My Share Title", contentDescription: "Lorem ipsum dolor sit amet.", imageURL: imageURL, peopleIDs: ["1561082740838259"], placeID: "166793820034304", ref: "myRefId")

}

I included a link to an online converter as a comment (actually I just left it in, the converter adds it!)
