to make it short, my iOS app download some data from a server and put it into an array. I wanna share the array count with the widget using the AppGroups. I save the array count number to UserDefaults like this:
if let userDefaults = UserDefaults(suiteName: "group.com.etc") {
// I save just a simple Int
userDefaults.set(loaded.count, forKey: userDefaultsKey)
}
Then on the widget side I have this class to retrieve the data:
class MyDataProvider {
static func getCountFromUserDefaults()-> Int {
if let userDefaults = UserDefaults(suiteName: "group.com.etc") {
let myFlag = userDefaults.integer(forKey: userDefaultsKey)
print("myFlag is \(myFlag)")
return myFlag
}
print("my flag is 0")
return 0
}
}
Last, my getTimeLine func is this
func getTimeline(in context: Context, completion: @escaping (Timeline<Entry>) -> ()) {
var entries: [SimpleEntry] = []
// Generate a timeline consisting of five entries an hour apart, starting from the current date.
let currentDate = Date()
for hourOffset in 0 ..< 5 {
let entryDate = Calendar.current.date(byAdding: .second, value: hourOffset * 30, to: currentDate)!
let entry = SimpleEntry(date: entryDate, myString: "\(MyDataProvider.getCountFromUserDefaults())")
print("my entry is \(entry)")
entries.append(entry)
}
let timeline = Timeline(entries: entries, policy: .atEnd)
completion(timeline)
}
The issue is that the number is always 0. On iOS side I'm sure the number is saved correctly but the widget get always 0 even when the iOS app is opened.
Do i mistake something?
