I'm trying to come up with a simple observable object in Swift and thought to use RxSwift. I couldn't find a simple example to do something like this:
protocol PropertyObservable {
typealias PropertyType
var propertyChanged: Event<(PropertyType, Any)> { get }
}
class Car: PropertyObservable {
typealias PropertyType = CarProperty
let propertyChanged = Event<(CarProperty, Any)>()
dynamic var miles: Int = 0 {
didSet {
propertyChanged.raise(.Miles, oldValue as Any)
}
}
dynamic var name: String = "Turbo" {
didSet {
propertyChanged.raise(.Name, oldValue as Any)
}
}
}
The above is pure Swift solution for observables from this blog post; I really like how it's a protocol-based solution and not invasive. In my case, I have an object in my project where each property is set asynchronously under the hood (bluetooth device). So I need to observe/subscribe to the changes instead of getting/setting the properties in real-time.
I keep hearing RxSwift will do just that and more. However, I can't find a simple example to match above and beginning to think RxSwift is overkill for my need? Thanks for any help.
