GPS Track Navigation with MapKit?

I want to create a MKRoute from a list of MKMapPoints or coordinates. But apparently MKRoute can only be generated from a MKDirections request from Apple's servers.

The primary use of my app will be activities (eg hiking) in the back country where (1) a network connection likely won't be available and (2) there likely will not be a trail in Apple's map network.

For example I want to provide navigation for following a recorded GPS track or my only MKPolyLines.

Note that I am required to use MapKit (3rd party map SDKs are not an option for a number of reasons). It feels like a huge missed opportunity if MapKit doesn't allow Routes to be created from a predetermined list of coordinates.

Does anyone know of any solutions for this problem either somehow creating a MKRoute from a list of coordinates or a 3rd party library? I've searched but haven't had any luck finding a solution. It seems like something like this must exist so I thought I'd ask.

I had assumed that MKRoute could be used to provide real-time route guidance like in Apple Maps, but apparently it just creates an instruction list and display a polyline. So I guess even if I could create a MKRoute from a list of coordinates I couldn't accomplish what I want.

Is there any existing ways to provide realtime route guidance like in Apple Maps using MapKit?

There is not — you have found the available APIs where the system provides you with data and steps in a MKRoute, but you cannot create the MKRoute yourself. Enhancement requests are always welcome!
