RxSwift equivalent BehaviorSubject's .modify() method

Reactive BehaviorSubject has a modify method while exposes the values as inout and allows you to modify them. Any RxSwift property that allows similar behaviour?

I'm not aware of any property that allows this, but you could write your own extension for this.

extension BehaviorRelay {
    var inoutValue: Element {
        get { return value }
        set { accept(newValue) }
    }
}

// for example
extension BehaviorRelay where Element == Int {
    func increment() {
        inoutValue += 1
    }
}
