Access to saved UserDefaults

Forums > Swift

Hi all,

in my App I am saving some data to UserDefaults like this (taken from SwiftUI in 100 Days):

class Expirations: ObservableObject {
    @Published var items = [ExpItem]() {
        didSet {
            let encoder = JSONEncoder()
            if let encoded = try? encoder.encode(items) {
                UserDefaults.standard.set(encoded, forKey: "Items")
            }
        }
    }

    init() {
        if let items = UserDefaults.standard.data(forKey: "Items") {
            let decoder = JSONDecoder()
            if let decoded = try? decoder.decode([ExpItem].self, from: items) {
                self.items = decoded

                return
            }
        }

        self.items = []
    }
}

Now I would like to access to UserDefaults "Items" from another SwiftUI Class. But I assume that I get a Struct of ExpItem back; I would like to get those values and present them in a "picker" (using List + ForEach), but I do not know how to do it.

Any hints?

Thanks

   

Hi MarcoGT

Your need to create an instant of it let expirations = Expirations() then you can access the proprety.

struct ContentView: View {
    let expirations = Expirations()

    var body: some View {
        List {
            ForEach(expirations.items) { item in
                Text("\(item.name) is \(item.age) years old")
            }
        }
    }
}
