swift 混编OC 使用OC NSDictionary

 

OC 属性

@property (nonatomic, strong) NSDictionary * _Nullable extraData;

 

swift使用 打印

?

1	Dictionary<AnyHashable, Any>

?

1 2 3 4 5 6 7 8 9 10 11

(lldb) po extraData ▿ Optional<Dictionary<AnyHashable, Any>>   ▿ some : 2 elements     ▿ 0 : 2 elements       ▿ key : AnyHashable("localAddress")         - value : "localAddress"       - value : "江苏省无锡市锡山区厚桥街道厚安路无锡锡东科技产业园"     ▿ 1 : 2 elements       ▿ key : AnyHashable("virtual")         - value : "virtual"       - value : true

　　

 

直接使用  下边代码会失败

if let dict = self.extraData as? [String:Any]{

}

 

应该使用

        if let dict = self.extraData as? Dictionary<String, Any>{
            let aVirtual = dict["virtual"] as? Bool ?? false
            let localAddress = dict["localAddress"] as? String ?? ""
        }
