RemoteConfig supports property wrappers for Swift 5.1 or later

[fumito-ito]

Property wrapper is the feature available for Swift 5.1 or later.

A property wrapper adds a layer of separation between code that manages how a property is stored and the code that defines a property.

This function has great compatibility with Remote Config. In my use case , it will be able to use fetching feature flags.

struct FeatureFlags {
    @RemoteConfig(forKey: "is_new_feature_available")
    var isNewFeatureAvailable: Bool
}

Wrapped Value

It returns just remote config value as following.

@RemoteConfig(forKey: "is_new_feature_available")
var isNewFeatureAvailable: Bool // return remote config value

and also provides binding for SwiftUI as DynamicProperty

@RemoteConfig(forKey: "is_new_feature_available")
var isNewFeatureAvailable: Bool

Toggle(isOn: isNewFeatureAvailable) {
     Text("wonderful new feature")
}

Other APIs

It provides additional information for Remote Config value

@RemoteConfig(forKey: "is_new_feature_available")
var isNewFeatureAvailable: Bool

_isNewFeatureAvailable.key // return 'is_new_feature_available'
_isNewFeatureAvailable.lastFetchStatus // return Last fetch status. The status can be any enumerated value from `RemoteConfigFetchStatus`.
_isNewFeatureAvailable.lastFetchTime // return Last successful fetch completion time
