Unarchive Array with NSKeyedUnarchiver unarchivedObject(ofClass:from:)

Question

Since upgrading to Swift 4.2 I\'ve found that many of the NSKeyedUnarchiver and NSKeyedArchiver methods have been deprecated and we must now use the type method static

You are likely looking for this:

if let widgetsData = UserDefaults.standard.data(forKey: USER_DEFAULTS_KEY_WIDGET_DATA) {
        if let widgets = (try? NSKeyedUnarchiver.unarchivedObject(ofClasses: [NSArray.self, WidgetData.self], from: widgetsData)) as? [WidgetData] {
            // your code
        }
    }
