Swift 插入filterSelections:[字符串：任意]

我有一个字符串：任意数组，如下所示

public var filterSelections: [String: Any] = [
    "myFilter": ["all"],
    //"fromDate": Date = Date()
    //"searchByName": String = ""
]

我想将值“sampleFilterValue”添加到默认值“all”中，因此数组如下所示

[
  "myFilter": ["all", "sampleFilterValue"]
]

你可以试试

if var res = filterSelections["myFilter"] as? [String] { 
   res.append("sampleFilterValue")
   filterSelections["myFilter"] = res
}

---

如果var filters=filterSelections[“myFilter”]as？[String]{filters.append（“sampleFilterValue”）；filterSelections[“myFilter”]=filters}

？应避免使用具有异构值类型的词典。改用结构或类。
