iOS/swiftで緯度・経度から2点間の距離を算出する

Posted at
let 現在地の緯度: Double = 135.5258549
let 現在地の経度: Double = 34.6873527
let 行き先の緯度: Double = 139.75313186645508
let 行き先の経度: Double = 35.68525668970075
let 現在地の位置情報: CLLocation = CLLocation(latitude: 現在地の緯度, longitude: 現在地の経度)
let 行き先の位置情報: CLLocation = CLLocation(latitude: 行き先の緯度, longitude: 行き先の経度)
距離 = 行き先の位置情報.distanceFromLocation(現在地の位置情報)
