extension Reactive where Base: Permission {
    
    /// Reactive wrapper for `Permission` instance.
    public var permission: Observable<PermissionStatus> {
        return Observable.create { (observer) in
            self.base.request { observer.onNext($0) }

Usage

RxPermission makes a rx.permission Observable that you can subscribe in order to receive signals.

Sample code

Permission
    .contacts
    .rx.permission
    .subscribe(onNext: { status in
        print("Status: \(status)")
    })
    .addDisposableTo(disposeBag)

Available statuses

public enum PermissionStatus {
    case authorized
    case denied
    case disabled
    case notDetermined
}
