ios – Swift是否可以从轻量级通用Objective-c类继承？

我有两个类,基类在Obj-c中,子类在 Swift中.

Obj-c类使用新的XCode 7的轻量级通用功能,定义如下：

@interface BaseController<T: SFObject *> : UIViewController
@property(nonatomic,strong) T model;
@end

这适用于Obj-c子类.

现在对于Swift,如果我像往常一样定义泛型类型,我会收到以下错误：

Cannot specialize non-generic type ‘BaSEObjcController’.

我的第二课定义如下：

class SwiftController: BaSEObjcController<SFUser> {

}

任何帮助,将不胜感激.
谢谢.

解决方法

从 Interacting with Objective-C APIs开始：

NOTE

Aside from these Foundation collection classes,Objective-C
lightweight generics are ignored by Swift. Any other types using
lightweight generics are imported into Swift as if they were
unparameterized.

所以目前这是不可能的.从你可以看到
“生成接口”助手视图,您的Objective-C类被导入
以斯威夫特为例

public class BaseController : UIViewController {
    public var model: SFObject!
}

这也在Apple开发者论坛中讨论过：

> Objective-C generics not visible from Swift?

随意提交增强错误报告！
