在Swift中将任何字典数组转换为String

Question

Convert [String:Any] dictionary array to [String:String] in Swift

I have an array of dictionary <String,Any> type. Now I want to convert to string because I want to show data in textField and text field not understand Any data type.

My data like this:

var myarr = [[String:Any]]()

[
    [
        "Area" : "",
        "Good" : "-",
        "Level" : 2,
        "Link" : "<null>",
        "Photo" : "-",
        "Repair" : "-",
        "Section" : "Others"
    ],

    [
        "Area" : "",
        "Good" : "N",
        "Level" : 2,
        "Link" : "http://google.com",
        "Photo" : 1,
        "Repair" : "Y",
        "Section" : "Grounds"
    ]

]

and I want new Array Dictionary:

var myarr = [[String:String]]()

Answer 1

Map is your friend, maybe something like

let stringDictionaries: [[String: String]] = myarr.map { dictionary in
    var dict: [String: String] = [:]
    dictionary.forEach { (key, value) in dict[key] = "\(value)" }
    return dict
}

Here is one solution that actually gives the correct results:

let myarr = [
    [
        "Area" : "",
        "Good" : "-",
        "Level" : 2,
        "Link" : "<null>",
        "Photo" : "-",
        "Repair" : "-",
        "Section" : "Others"
    ],

    [
        "Area" : "",
        "Good" : "N",
        "Level" : 2,
        "Link" : "http://someurl",
        "Photo" : 1,
        "Repair" : "Y",
        "Section" : "Grounds"
    ]
]


var newarr = [[String:String]]()
for dict in myarr {
    var newdict = [String:String]()
    for (key, value) in dict {
        newdict[key] = "\(value)"
    }
    newarr.append(newdict)
}
print(newarr)

Output:

[["Level": "2", "Area": "", "Good": "-", "Link": "<null>", "Repair": "-", "Photo": "-", "Section": "Others"], ["Level": "2", "Area": "", "Good": "N", "Link": " http://someurl ", "Repair": "Y", "Photo": "1", "Section": "Grounds"]]

You can create new dictionary using following code:

var newArray:[[String: String]] = []
for data in myarr {
    var dict: [String: String] = [:]
    for (key, value) in data {
        let strData = String(describing: value)
        dict[key] = strData
    }
    newArray.append(dict)
}
