To create an observable array using RxSwift
in Swift 2, I use to do this:
[1, 2, 3].toObservable().subscribeNext { print($0) }
But in Swift 3, it doesn't work anymore, I got this error:
Value of type '[Int]' has no member 'toObservable'
How can I create an RxSwift
observable array from a swift array?
In Swift 3 using RxSwift 3.0
I will do that like this:
var array: Variable<[Int]> = Variable([1, 2, 3])
array.asObservable().subscribe(onNext: {
updatedArray in
print(updatedArray)
})
array.value.append(4) // it will trigger `onNext` event
So the main difference is that you have to create an Variable
object instead of using an explicit array.
