Wow, I didint expect such a complex answer! Many thanks dor your help and for the quicktype url - it would be useful for the next time. Your solution works fine, but the songs are changing, while on my labels data is still the same. Do you know a solution how to force an update from my api? Is it possible? Data in it is changing when the song is changing, so when the api data is changing. Thank you in advance.

Cool! Thank you. My mistake was that I was trying to add pause.png and play.png in sender.setImage(playImage, for: .normal). I did one change - I have replaced pauseImage and playImage. Now it looks more logical :) Have a nice day and thank you for your time.

Hi @Claude31, I would like to have one button, which change the image from play.png to pause.png, whether the stream is playing or not. Now, as you can find in my code, I have two buttons: play and stop. I just need one button with play and pause image depending on whether stream is playing or not. When the user open the app, the play image on the button should be visible and the button should start an action of playing the stream, than when the stream is playing, user should see pause button to stop the stream etc.

Ok, my mistake - Just added mapView.addOverlays(circles!) in viewdidload. Outside viewdidload it wasnt initialized.

Yes, sorry it is: class ViewController: UIViewController, MKMapViewDelegate{ Now, the new struct is correct: struct Szczyt { var name: String var describtion: String var lattitude: CLLocationDegrees var longtitude: CLLocationDegrees var coordinate: CLLocationCoordinate2D { .init(latitude: lattitude, longitude: longtitude) // here Im trying to create var for this property to set it for all objects         }     } }
