You can use the @objcMembers attribute on your whole class or struct. You need to choose the classes on which you want to apply the @objcMembers attributes.

You can follow this tutorial.

According to Apple doc:

When a Swift class introduces many new methods or properties that require behavior from the Objective-C runtime, use the @objcMembers attribute in the declaration of that class. Applying the @objcMembers attribute to a class implicitly adds the @objc attribute to all of its Objective-C compatible members. Because applying the @objc attribute can increase the compiled size of an app and adversely affect performance, only apply the @objcMembers attribute on declarations when each member needs to have the @objc attribute applied.
