How to validate UserDefault value will or empty using Swift

Question

I am implementing UserDefault string value ! = nil or !="" ! = nil or !="" but my validation not working. How do I solve this?

if((UserDefaults.standard.string(forKey: "name")) != nil || UserDefaults.standard.string(forKey: "name") != "") {
    self.items.insert(UserDefaults.standard.string(forKey: "name") ?? "", at: 5) // Always reaching here....
}

Answer 1

Check if there is value for the key by optional unwrapping. Then check if it is not empty. Then insert it to the array.

if let value = UserDefaults.standard.string(forKey: "name"), !value.isEmpty {
    items.insert(value, at: 5)
}

The reason the if is executed every time in your case is because you are using an OR ( || ) instead of AND ( && ). So, the second condition is true even when there is no value for the key in the UserDefaults .

PS: Make sure the array has at least 6 items before you call insert at 5.
