Observable is the easiest way to observe values in Swift.

How to

Create an Observable

var position = Observable(CGPoint.zero)

Add an observer

position.observe { p in
    // handle new position
}

Change the value

position.value = p

Memory management

For a single observer you can store the returned Disposable to a variable

disposable = position.observe { p in

For multiple observers you can add the disposable to a Disposal variable

position.observe { }.add(to: &disposal)

And always weakify self when referencing self inside your observer

position.observe { [weak self] position in

Installation

CocoaPods

Observable is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'Observable'
