Hi Ramzy,

Your answer is right! The only reason why you didn't passed the challenge is just because you did the code only for the Eiffel Tower, but you have to do it also for the Great Pyramid and the Sydney Opera House!

here is the code:

func coordinates(for location: String)->(Double, Double){
    var d: Double
    var dd: Double
    if(location == "Eiffel Tower"){
        d = 48.8582
        dd = 2.2945
    }
    else if(location == "Great Pyramid"){
        d = 29.9792
        dd = 31.1344
    }
    else if(location == "Sydney Opera House"){
        d = 33.8587
        dd = 151.2140
    } else {
        d = 0
        dd = 0
    }
    return (d,dd)
}
