Common Protocol for all Dynamic<T> classes? about bond

[srdanrasic]

Hi @rvangraan,

You should be able to do that yourself with extensions, like this:

protocol DynamicProtocol {}
extension Dynamic: DynamicProtocol {}

Then you can declare an array of Dynamics of any generic type:

var dynamicValues = [DynamicProtocol]()

dynamicValues.append(Dynamic<Int>(0))
dynamicValues.append(Dynamic<String>("hi"))

That being said, for whatever reason you might need this, I'm not sure it's good approach. First of all, type information will be lost, so you'll need to cast to right type before binding:

(dynamicValues[1] as! Dynamic<String>) ->> nameLabel

Additionally, if you replace a dynamic element in the array, the binding will be lost. For example, if you do:

dynamicValues[1] = Dynamic<String>("Tim")

Then updating that new dynamic would not propagate to name label because that new Dynamic is not bound to it.

I'd strongly recommend against doing all this.

Thanks

PS You should always declare your Dynamics as constants, using let keyword:

private let dynDescription = Dynamic(description)
private let dynNetAmount = Dynamic(Money())
private let dynVatAmount = Dynamic(Money())
