Set request timeout on RXMoyaProvider - alamofire

Question

I am using Moya with RxSwift and I am trying to set the request timeout for the network call (API Calls) using below code as suggested :
which is including the custom Alamofire Manager when declaring your Provider
lazy var provider: RxMoyaProvider<CAPProviderAPI> = {
return RxMoyaProvider<CAPProviderAPI>(endpointClosure: Utility.getEndPointClosure(forProviderType: .authorized), manager: DefaultAlamofireManager.sharedManager, plugins: [NetworkActivityPlugin(networkActivityClosure: networkActivityClosure)])
}()
but I am getting an error saying : Use of unresolved identifier 'networkActivityClosure'

I would like to share with you the way I did it. It might not answer your question, but it shows the way to achieve the desired behavior using RxSwift operators.
I have some function which accepts timeout parameter and makes a request:
func request(timeout: TimeInterval, ...other params) -> Observable<...>
Inside this function I transform timeout to Observable this way:
func observableTimeout(timeout: TimeInterval, ...other params) -> Observable<...> {
return Observable<Int>
.timer(timeout, period: ..., scheduler: ...)
.take(1)
.map(to: ...) // map to timeout error
}
If the timeout takes place - I need to cancel the request. I have made some flatMapLatest analogue which also accepts a cancel signal:
public extension Observable {
public func flatMapLatest<T>(cancel: Observable<T>, factory: #escaping (E) throws -> Observable<T>) -> Observable<T> {
let observableNormal = self
.flatMap({ try factory($0) })
return Observable<Observable<T>>
.of(cancel, observableNormal)
.merge()
.take(1)
}
}
As a result, the request function will work this way:
func request(timeout: TimeInterval, ...other params) -> Observable<...> {
let cancel = observableTimeout(timeout: timeout, ...)
let factory = ...// your observable factory which makes a request using Moya
return Observable
.just((), scheduler: ...)
.flatMapLatest(cancel: cancel, factory: factory)
}
