Custom init with id to ViewController in Objective-C from Swift code

Question

I need help you with convert my Swift code to Objective-c.

There is my Swift code.

 self.show(ChatViewController(conversation: conversation!), sender: self)

I have no idea how to convert them to with init "conversation". This is Id of conversation for my chat in Socket.

 ChatViewController *chatVC = [[ChatViewController alloc] init];
            [vc showViewController: chatVC sender:self];

Answer 1

All Swift stuff must be marked @objc public to be visible in Objective-C. In this case that would be the ChatViewController class, its init(conversation:) , and whatever the conversation type is.

If you do that correctly, Objective-C should be able to import your generated interface header (find this in your build settings, it usually looks like "AppName-Swift.h").

Then the Swift methods would be automatically converted to Objective-C style methods so you would be able to call

ChatViewController *chatVC = [[ChatViewController alloc] initWithConversation:converstaion];

Answer 2

May be Swift can't bridge your conversation object

Answer 3

It is not clear what conversation type is, but swift constructor

ChatViewController(conversation: conversation!)

in Objective-C is

ChatViewController *chatVC = [[ChatViewController alloc] 
    initWithConversation:conversation];
