How to create and add values to Dictionary in swift
提问by Varun Naharia
I want to create a Dictionary in swift with different type of data(array, string,dictionary)I am able to insert new data to a key but having difficulty in appending more values to them here is the json for the dictionary
我想用不同类型的数据（数组、字符串、字典）快速创建一个字典我能够将新数据插入到一个键中，但在向它们附加更多值时遇到困难，这里是字典的 json
{
"GenInfo": {
"First Name":"Varun",
"Last Name":"Naharia",
"Phone No":"123456789"
},
"LangInfo": ["Hindi","English","Urdu","French"],
"EduInfo":
[
{
"Collage":"CIITM",
"Year":"2009",
"Degree":"BCA"
},
{
"Collage":"Dept. Of Comp. Sci. & Infor. University Of Kota",
"Year":"2013",
"Degree":"MCA"
}
]
}
I want to add these values to dictionary one by one like first GenInfo, then first language of LangInfo then EduInfo
我想将这些值一个一个地添加到字典中，例如第一个 GenInfo，然后是 LangInfo 的第一种语言，然后是 EduInfo
Lang Info
朗信息
EduInfo
教育资讯
I Used dict["GenInfo"] = ["FirstName":first,"LastName":last,"Phone":phone]to add the GenInfo in the dic where first and last is the variable with value.
我曾经dict["GenInfo"] = ["FirstName":first,"LastName":last,"Phone":phone]在 dic 中添加 GenInfo，其中 first 和 last 是带值的变量。
EDIT #1var dict = Dictionary<String, Any>()
编辑#1var dict = Dictionary<String, Any>()

This is a known issue, apparently not fixed yet (see Is it possible to have a dictionary with a mutable array as the value in Swift)
这是一个已知问题，显然尚未修复（请参阅是否可以将具有可变数组的字典作为 Swift 中的值）
The workaround would be to create a new variable with your array and then assign it back:
解决方法是使用数组创建一个新变量，然后将其分配回：
var dict = [String: AnyObject]()
dict["GenInfo"] = ["FirstName":"first","LastName":"last","Phone":"phone"]
dict["Language"] = ["langage1", "langage2"]
if var languages = dict["Language"] as? [String] {
languages.append("langage3")
dict["Language"] = languages
}
