Unable to get details for a place using Google Places API - "Cannot invoke 'lookUpPlaceID' "

I'm trying to get details about a place using the Google Places API for iOS. When attempt to call the lookUpPlaceID function, receiving the following Swift compiler error:

Cannot invoke 'lookUpPlaceID' with an argument list of type '(String, callback: (GMSPlace!, _) -> Void)'

    let placeID = "ChIJV4k8_9UodTERU5KXbkYpSYs"

    placesClient!.lookUpPlaceID(placeID, callback: { (place: GMSPlace!, error) -> Void in
        if error != nil {
            println("lookup place id query error: \(error.localizedDescription)")
            return
        }

        if place != nil {
            println("Place name \(place.name)")
            println("Place address \(place.formattedAddress)")
            println("Place placeID \(place.placeID)")
            println("Place attributions \(place.attributions)")
        } else {
            println("No place details for \(placeID)")
        }
    })

I'm using the example code available in the Google Places API documentation here:

https://developers.google.com/places/ios/place-details#get-place

The placesClient is an object of type GMSPlacesClient. Earlier in the code, I am able to successfully call the placesClient autcompleteQuery function, so I don't think it's a problem with my placesClient.

Any help or suggestions would be greatly appreciated.

In the callback, you need to replace the type (GMSPlace) with the variable name that you want to use, which you correctly did for error.

It should be something like:

let placeID = "ChIJV4k8_9UodTERU5KXbkYpSYs"

placesClient!.lookUpPlaceID(placeID, callback: { (place, error) -> Void in
    if error != nil {
        println("lookup place id query error: \(error!.localizedDescription)")
        return
    }

    if let p = place {
        println("Place name \(p.name)")
        println("Place address \(p.formattedAddress)")
        println("Place placeID \(p.placeID)")
        println("Place attributions \(p.attributions)")
    } else {
        println("No place details for \(placeID)")
    }
})

Also, make sure to unwrap those optional variables (both place and error) before using them, by doing force unwrapping (!), like I did for error above, or by using if let, like I did for place.

Hope this helps.
