UISwitch Status 到 Firestore

Question

我目前正在构建一个用户创建机制，我有 8 个 UI 开关来确定某人是否对食物过敏。我为每个开关创建了一个@IBOutlet，现在将它们包含在文档中。我在添加文本字段时没有问题：

let db = Firestore.firestore()
db.collection("users").addDocument(data: ["firstname":firstname, "lastname":lastname, "username":username, ]

我想做的是扩展该语法以在用户创建时添加 8 UISwitch 的状态。

Firebase 和应用程序开发的新手，但尝试了谷歌搜索我能想到的一切。预先感谢您的帮助！

更新好的，所以我一定还是在这里做错了什么，但我想我已经接近了：

import FirebaseAuth

您可以使用 isOn 获取 UISwitch

的状态

let peanutAllergySwitch = UISwitch()    

let db = Firestore.firestore()
let data = [
  "firstname":firstname, 
  "lastname":lastname, 
  "username":username, 
  "allergicToPeanuts": peanutAllergySwitch.isOn
]

db.collection("users").addDocument(data: data)
