How can I make an Array with Dictionaris in SwiftUI, and then call them?-CodePudding

so simple / hard question here.. So I want to have a list of dictionaries titles in an array, then use the array to call a random dictionary

in the textfield I want dic1 "A" ("first")

how can I get this?

 let dic1 = [
"A" : "first",
"B" : "second"]
 let dic2 = [
"A" : "one",
"B" : "two"
]

var dicArray = ["dic1", "dic2"]

text("\(dicArray[0])")

CodePudding user response：

Besides removing the quotes when you instantiate dicArray, you need to do more work in Text. The way you instantiated dicArray, you made it an [String], not an [[String:String]]. The full view would be:

struct DictView: View {
    let dic1 = [
        "A" : "first",
        "B" : "second"]
    let dic2 = [
        "A" : "one",
        "B" : "two"
    ]
    
    var dicArray: [[String:String]]
    init() {
        dicArray = [dic1, dic2]
    }
    
    var body: some View {
        Text("\(dicArray[0]["A"] ?? "")")
    }
}

Remember, because it is a dictionary, there is no guarantee that there is a key:value for "A" so you have to deal with the optional as well.
