can somebody help me,,, how can I use the key of dictionaries to assign values for instances?

I want to use the structure to assign instances for urologyResidents array items, but I had error when I want to use doctorBleep and doctorId dictionaries to declare id and bleep properties. this is the code (sorry I don't know how to do it)

struct ResidentInfo {
    var name : String
    var level : String
    var id : [Int]
    var bleep : [Int]
}

var urologyResidents = ["Hussam", "Ahmed", "Alhassan:", "Anas", "Saleh"]

let urologyLevels = [ "R1", "R2", "R3", "R4", "R5"]

var doctorBleep = [
    "Hussam" : 1517,
    "Ahmed": 1784,
    "Alhasaan": 1417,
    "Anas": 1508,
    "Saleh" : 1612
]

var doctorId = [
    "Hussam" : 14977,
    "Ahmed": 15510,
    "Alhasaan": 52291,
    "Anas": 52305,
    "Saleh" : 51542
]


let Hussam = ResidentInfo(name: urologyResidents[0], level: urologyLevels[0], id: doctorId["Hussam"], bleep:  doctorBleep["Hussam"])

Hello,

You can do some changes to your code to make it work, from the dictionary you want to pass an ID, and it should return a Int, therefore in your struct you should change the store property to be of type "Int" instead of "[Int]"

struct ResidentInfo {
    var name : String
    var level : String
    var id : Int          // Instead of [Int]
    var bleep : Int.   // Instead of [Int]
}

var urologyResidents = ["Hussam", "Ahmed", "Alhassan:", "Anas", "Saleh"]

let urologyLevels = [ "R1", "R2", "R3", "R4", "R5"]

var doctorBleep = [
    "Hussam" : 1517,
    "Ahmed": 1784,
    "Alhasaan": 1417,
    "Anas": 1508,
    "Saleh" : 1612
]

var doctorId = [
    "Hussam" : 14977,
    "Ahmed": 15510,
    "Alhasaan": 52291,
    "Anas": 52305,
    "Saleh" : 51542
]


let Hussam = ResidentInfo(name: urologyResidents[0], level: urologyLevels[0], id: doctorId["Hussam"]!, bleep:  doctorBleep["Hussam"]!)
