Usage
import UserDefault
struct Defaults {
@UserDefault("is_discount_provided", defaultValue: false)
static var isDiscountProvided: Bool
}How to Modify?
Well, that's pretty simple. You only have to access the variable through the Defaults struct, and set it the value.
Defaults.isDiscountProvided = trueIn addition, Custom models which conforms Codable protocol can be stored too.
Custom models
struct User: Codable {
let firstName: String
let lastName: String
}
struct Defaults {
@UserDefault("default_user")
static var defaultUser: User?
}You can specify any UserDefaults suite for each one. If you want to store on standard suite, no needed to specify it. Default is UserDefaults.standard.
Usage of custom UserDefaults suite
struct Contact: Codable {
let firstName: String
let lastName: String
let phoneNumber: String
}
private let appSuite = UserDefaults(suiteName: "com.strawb3rryx7.userdefault.appsuite")!
private let customSuite = UserDefaults(suiteName: "com.strawb3rryx7.userdefault.customsuite")!
struct Defaults {
@UserDefault("primary_contact", suite: appSuite)
static var primaryContact: Contact?
@UserDefault("has_seen_purchase_screen", defaultValue: false, suite: customSuite)
static var hasSeenPurchaseScreen: Bool
}
