Parse results from JSON to a list dynamically - json

Question

I do a JSON Request and get some information.
func parseJSON(poiData: Data) {
let decoder = JSONDecoder()
do {
let decodedData = try decoder.decode(POIData.self, from: poiData)
POIManager.POIname_One = decodedData.results[0].name
POIManager.POIplaceid_One = decodedData.results[4].place_id
POIManager.POIvicinity_One = decodedData.results[4].vicinity
POIManager.POIlong_One = decodedData.results[0].geometry.location.lat
POIManager.POIlat_One = decodedData.results[0].geometry.location.lng
POIManager.POIname_Two = decodedData.results[1].name
POIManager.POIplaceid_Two = decodedData.results[1].place_id
POIManager.POIvicinity_Two = decodedData.results[1].vicinity
POIManager.POIlong_Two = decodedData.results[1].geometry.location.lat
POIManager.POIlat_Two = decodedData.results[1].geometry.location.lng
POIManager.POIname_Three = decodedData.results[2].name
POIManager.POIplaceid_Three = decodedData.results[2].place_id
POIManager.POIvicinity_Three = decodedData.results[2].vicinity
POIManager.POIlong_Three = decodedData.results[2].geometry.location.lat
POIManager.POIlat_Three = decodedData.results[2].geometry.location.lng
} catch {
print(error)
}
}
In a different Swift file it put the results from the request in a list like this:
#IBAction func kategorieEins(_ sender: UIButton) {
//Eigene Standort soll hier gezeigt werden/aktualisierter Standort
locationManager.delegate=self
let marker1 = GMSMarker()
marker1.position = CLLocationCoordinate2D(latitude: POIManager.POIlong_One, longitude: POIManager.POIlat_One)
marker1.title = POIManager.POIname_One
marker1.snippet = "Marker1_0"
marker1.map = mapView
let marker2 = GMSMarker()
marker2.position = CLLocationCoordinate2D(latitude: POIManager.POIlong_Two, longitude: POIManager.POIlat_Two)
marker2.title = POIManager.POIname_Two
marker2.snippet = "Marker2_0"
marker2.map = mapView
let marker3 = GMSMarker()
marker3.position = CLLocationCoordinate2D(latitude: POIManager.POIlong_Three, longitude: POIManager.POIlat_Three)
marker3.title = POIManager.POIname_Three
marker3.snippet = "Marker3_0"
marker3.map = mapView
}
As you can see this whole thing is not dynamic it is static. I write down how many markers i want to have created.
Is there a way to do this automatically? Especially when I dont know how much information there is in the json file and how many markers should be created.

Answer 1

I solved it now.
I tried:
decodedData.results.forEach {
print($0.name)
print($0.place_id)
}
