I just started programming in Swift and I am a complete beginner.
I wanted to write a function or class that, by receiving the coordinates, if there is a photo in MKLookAround.request, saves a photo of the desired location using MKLookAround.Snapshotter, but I don't know how to use the mapkit ready classes.
I don't want to use swiftUI, I just want to save pictures for a number of coordinates from different places.

That uses this Error object:
enum LookaroundError: Error {
case unableToCreateScene
}
For more information, see WWDC 2022 What’s new in MapKit or check out the use of MKLookAroundSnapshotter in their sample project.
And if you want to write that to a file get either the PNG (pngData) or JPG (jpgData) representation and write it to a file:
let image = try await snapshotImage(for: coordinate)
let url = try FileManager.default
.url(for: .applicationSupportDirectory, in: .userDomainMask, appropriateFor: nil, create: true)
.appending(component: "test.png")
try image.pngData()?.write(to: url)
Or alternatively, you might want to present a user a UI whereby they can specify what they want to do with the image, via UIActivityViewController:
let share = UIActivityViewController(activityItems: [image], applicationActivities: nil)
self.present(share, animated: true)
