我有这套从Firebase获得的字典数据。但是，如何将其保存到阵列中？我想要的数据是移动数据和名称。

这是我的代码：

func retrieveLists() {

    ref = Database.database().reference()

    ref.child("users").child("60123456789").child("contact_lists").observeSingleEvent(of: .value, with: { (snapshot) in

        let value = snapshot.value as? NSDictionary
        print("value:\(value)")

    }) { (error) in

        print(error.localizedDescription)

    }


    }

Answer 1

使用以下代码作为参考：-

if let firebaseDic = snapshot.value as? [String: AnyObject] {
    for (_, value) in firebaseDic.enumerated() {
        let mobileNumber = value.value["mobile"]!! as! String                               
    }
}

Answer 2

您可以尝试

struct Item {
    let mobile:String
    let name:String
}

//

var content = [Item]()

for k in value.allKeys {

    if let res = value[k] as? [String:String] , let mobile = res["mobile"] , let name = res["name"] {

        content.append(Item(mobile: mobile, name: name))
    }

}

将数据保存到数组[Swift]
