搜到的相關(guān)資料基本來(lái)自這個(gè)帖子Inherit from a Swift class in Objective C
。一樓回復(fù)已經(jīng)說(shuō)的很明確了，Objective-C不能繼承Swift類。

Unfortunately, it's not possible to subclass a Swift class in Objective-C. Straight from the docs: You cannot subclass a Swift class in Objective-C.

那么換個(gè)思路，為什么一定要用繼承呢？用category可以嗎？經(jīng)過(guò)我的測(cè)試是可以的，代碼如下：

Swift文件

import UIKit

@objcMembers open class TestModel: NSObject {
    var testName: String = String()
}

OC的.h文件

#import <Foundation/Foundation.h>
// 橋接文件
#import "****-Swift.h"


@interface TestModel (Add)
- (void)configTestName;
@end

OC的.m文件

#import "TestModel+Add.h"

@implementation TestModel (Add)

- (void)configTestName {
    self.testName = @"12323";
}

@end
