How to retrieve and assign a NSDate object from NSUserDefaults?
Swift 3/4/5 version using Date
(type alias) instead of NSDate
:
let yourDate = UserDefaults.standard.object(forKey: "yourKey") as? Date
UserDefaults.standard.set(yourDate, forKey: "yourKey")
Remember to use conditional cast operator as?
to avoid crash if there is no date yet under "yourKey" in UserDefaults
.
Set your date object as follows:
UserDefaults.standard.set(Date(), forKey:"yourKey")
Retrieve it using:
UserDefaults.standard.object(forKey: "yourKey") as? Date
Date will be optional of course, because it might never have been set.
