AppleMapsMiddleware

This package provides middlewares for SwiftRex handling MapKit related actions.

ETA

In order to estimate the time of arrival, the first step is to create a Journey object containing facts about the intended route. This object can then be used to create an ETAAction, which, after it is dispatched, is handled by the eta middleware (AppleMapsMiddleware.eta). The accompanying reducer (AppleMapsReducer.eta) updates the state (ETAState) accordingly.

struct ETAAction {
    static let cancel: ETAAction
    static func calculateETA(for journey: Journey) -> ETAAction
}

enum ETAState {
    case initial
    case estimating
    case failed(error: Error, journey: Journey)
    case received(MKDirections.ETAResponse)
    case canceled
}

Local Search

A dispatched LocalSearchAction object initializes a map related search, which is conducted by AppleMapsMiddleware.localSearch based on either a search query filtered by region and/or results types or a MKLocalSearchCompletion object. The AppleMapsReducer.localSearch object updates to current state with the resulting output of the middleware.

struct LocalSearchAction {
    static let cancel: LocalSearchAction
    static func search(for query: String, in region: MKCoordinateRegion?, resultTypes: MKLocalSearch.ResultType) -> LocalSearchAction
    static func search(for completion: MKLocalSearchCompletion) -> LocalSearchAction
}

enum LocalSearchState {
    case initial
    case searching
    case canceled
    case received([MKMapItem])
    case failed(Error)
}

Local Search Completer

The related AppleMapsMiddleware.localSearchCompleter middleware provides completions for a query fragment received by an incoming LocalSearchCompleterAction object. Before the middleware sends completions, it needs to be activated (or: initialized) with an action containing result types, an optional points of interest filter and a possible region to reduce the search spectrum.

struct LocalSearchCompleterAction {
    static let cancel: LocalSearchCompleterAction
    static func initilize(resultTypes: MKLocalSearchCompleter.ResultType, filter: MKPointOfInterestFilter?, region: MKCoordinateRegion?) -> LocalSearchCompleterAction
    static func requestCompletionsFor(queryFragment: String) -> LocalSearchCompleterAction
}

enum LocalSearchCompleterState {
    case initial
    case initilized
    case searching
    case received([MKLocalSearchCompletion])
    case failed(Error)
    case canceled
}
