Plotting values from an NSArray in MapKit

Question

Edit: added Dump(lat) Edit2: tried compactMap

I am having trouble retrieving values from an SQL database and plotting longitude and latitude from each row in the database as a new pin on the Map. The problem arises from when I try to retrieve the values from the array

var feedItems: NSArray = NSArray()

func itemsDownloaded(items: NSArray) {
    
    feedItems = items
    var i = 0
    for selectedLoc in feedItems {
        i+=1
        let lat = selectedLoc
        let lati = 55.74  /// should be gathered from the json extracted from the sql
        let longi = 10.88 /// should be gathered from the json
        let annotation = MKPointAnnotation()
        annotation.coordinate = CLLocationCoordinate2D(latitude: lati, longitude: longi)
        mapView.addAnnotation(annotation)
        }

    }

dump(lat) looks like this:

▿ Name: Optional("1"), Time_in: Optional("2021-11-13 00:00:00"), Latitude: Optional("55.73390° N"), Longitude: Optional(" 12.57243° E") #0
  - super: NSObject
  ▿ name: Optional("1")
    - some: "1"
  ▿ time_in: Optional("2021-11-13 00:00:00")
    - some: "2021-11-13 00:00:00"
  ▿ latitude: Optional("55.73390° N")
    - some: "55.73390° N"
  ▿ longitude: Optional(" 12.57243° E")
    - some: " 12.57243° E"
▿ Name: Optional("2"), Time_in: Optional("2021-11-13 00:00:00"), Latitude: Optional("54.73390° N"), Longitude: Optional(" 11.57243° E") #0
  - super: NSObject
  ▿ name: Optional("2")
    - some: "2"
  ▿ time_in: Optional("2021-11-13 00:00:00")
    - some: "2021-11-13 00:00:00"
  ▿ latitude: Optional("54.73390° N")
    - some: "54.73390° N"
  ▿ longitude: Optional(" 11.57243° E")
    - some: " 11.57243° E"
▿ Name: Optional("3"), Time_in: Optional("2021-11-13 00:00:00"), Latitude: Optional("56.73390° N"), Longitude: Optional(" 13.57243° E") #0
  - super: NSObject
  ▿ name: Optional("3")
    - some: "3"
  ▿ time_in: Optional("2021-11-13 00:00:00")
    - some: "2021-11-13 00:00:00"
  ▿ latitude: Optional("56.73390° N")
    - some: "56.73390° N"
  ▿ longitude: Optional(" 13.57243° E")
    - some: " 13.57243° E"

I just need to retrieve the latitude from this and insert it into the "lati" and " longi" variables. I have tried many many things such as

    let lati = lat[latitude]
    let lati = lat.latitude

These give the error: "Value of type 'NSArray.Element' (aka 'Any') has no member 'latitude'". I am sure it is just very simple but I am stuck. Can anyone help out a stupid newbie?

    let locs = feedItems.compactMap{ Int($0 as! String)}
