A simple GPX file parser written in Swift, which only depends on Foundation and CoreLocation. This parser is published under the GNU Affero General Public license. The main purpose of this parser is to extract way-points, route-points or track-points from a GPX file. All remaining metadata for these points is places inside a properties
dictionary. No further parsing is performed for nested data structures.
let url = URL(...)
let parser = try GPXParser(file: url)
parser.parse { result in
switch result {
case .success():
// The way-points
let waypoints = parser.waypoints
// All route-points from all routes combined
let routepoints = parser.routes.flatMap { route in
route.routepoints
}
// All track-points from all track segments for each track combined
let trackepoints = parser.tracks.flatMap { track in
track.segments.flatMap { segment
segment.trackpoints
}
}
case .failure(let error):
print("Error parsing the gpx file!")
}
} catch (let error) {
print("Error opening the gpx file!")
}
