Chaining tasks of different types

[ir-fuel]

I have tried all kinds of combinations, but it seems impossible to me to chain several tasks (in series) where the tasks have different result types and whereby each task upon error needs to stop the execution of all subsequent tasks. It's compile time error galore for me.

I also think the docs are lacking. They don't really show how to chain multiple tasks using the success/error handlers. The paragraph chaining tasks doesn't even show how to acutally chain tasks.

Can you provide some examples? This compiles for me:

func test() -> Task<Void> {
    let stringTask = Task("123")
    let intTask = Task(123)
    let voidTask = Task<Void>.emptyTask()    
    return stringTask.continueOnSuccessWithTask { task in
        return intTask.continueOnSuccessWithTask { task in
            return voidTask
        }
    }
}

Good point. I tried it again and now I have it working. No idea what happened previously

the emptyTask is internal scope. How can I use it, if I use Bolts as framework(using cocoapods/carthage)
