How to remove all data by a suite name from UserDefaults in Swift?

Question

I have created user defaults with names below,

let prefs1 = UserDefaults.init(suiteName: \"UserAccount\")
let prefs2 = UserDefaults.init(suiteName: \"UserInfo\")         


        

Answer 1

You can try

UserDefaults.standard.removeSuite(named: "UserAccount")

If you want to just remove the keys. You can go for following

func removeAllFor(defaults: UserDefaults) {
        let dictionary = defaults.dictionaryRepresentation()
        dictionary.keys.forEach { key in
            defaults.removeObject(forKey: key)
        }
    }

Then you can call it on default that you want to clear data for

removeAllFor(defaults: prefs1)

removeSuite(named:) : Removes a sub-searchlist added via -addSuiteNamed method

removePersistentDomain(forName: ) : Removes all values from the search list entry specified by ‘domainName’.
