How to check if the object returned is Array in Swift

Question

I have a declaration..

var cabResults = Dictionary<CabType, [CabResult]>()

Now I want to check if the object is present in the dictionary for a particular key.. which can be don by

if self.cabResults[currentCabType] != nil

Now I also want to check if the object returned by self.cabResults[currentCabType] is of type [CabResult]

How can I get this..?

if varName is Array<CabResult>{...}

I would use if let ... as? ...:

if let cabs = self.cabResults[currentCabType] as? [CabResult] {
    // yep
} else {
    // nope
}

You don't need to check is the object is will and do another check is that of any particular type, you can just do:

if let myObject = self.cabResults[currentCabType] as? [CabResult] {
    // myObject is not till and is of type myObject
} else {
    // the object is nil or it's not of type myObject
}
