问题
I have defined two Swift classes in my Xcode project. Everything else is Objective-C.
To use the classes in Objective-C I'm trying to import ProductModuleName-Swift.h but the file contains only the definition for one of the Swift classes. (SearchViewController)
This class is being exported:
class SearchViewController : UIViewController {
but this isn't:
public class Socket {
回答1:
From "Migrating Your Objective-C Code to Swift" in the "Using Swift with Cocoa and Objective-C" documentation:
To be accessible and usable in Objective-C, a Swift class must be a descendant of an Objective-C class or it must be marked @objc.
When you bring Swift code into Objective-C, remember that Objective-C won’t be able to translate certain features that are specific to Swift. For a list, see "Using Swift from Objective-C".
SearchViewController is a descendent of an Objective-C class, but Socket is not.
To make it usable in Objective-C, declare it as a subclass of NSObject:
public class Socket : NSObject { ...
or declare it as
@objc public class Socket { ...
