It is wrapper for UserDefaults.
UserDefaultsProxy is Type-safety, and Testable.
class AppSetting {
// String value. It isn't optional. It's needs default value.
static let userName = StringProxy(key: "userName", defaultValue: "unknown")
// Optional int value.
static let age = IntOptProxy(key: "age")
}
func doSomething() {
let userName = AppSetting.userName.value
let age = AppSetting.age.value
}
func updateAge(_ age: Int) {
AppSetting.age.value = age
}
There is no rule in Key. But do not duplicate.
if you would like to duplicate key check in debug build...
#if DEBUG
DuplicateKeyChecker.isCheckDuplicateKey = true
#endif
If you would like to test for UserDefaults, You can use mock objects.
class Tests: XCTestCase {
override func setUp() {
super.setUp()
UserDefaultsContainer.resolve = {
return UserDefaultsMock()
}
}
A new instance of UserDefaults mock is created each time it is executed.
