How to iterate through an array of coordinates to draw a CGPath?

Question

We have an array of coordinates and we want to loop through them to draw a path. This is how it looks with the values hardcoded:

 func createPath(){
        path.move(to: CGPoint(x: 32.7915055, y: -96.8028408))//1
        path.addLine(to: CGPoint(x: 32.79174845, y: -96.80252195))
        path.addLine(to: CGPoint(x: 32.7919914, y: -96.8022031))//2
        path.addLine(to: CGPoint(x: 32.791501100000005, y: -96.80235195))
        path.addLine(to: CGPoint(x: 32.7910108, y: -96.8025008))//3
        path.addLine(to: CGPoint(x: 32.791301700000005, y: -96.8020985))
        path.addLine(to: CGPoint(x: 32.7915926, y: -96.8016962))//4
        path.addLine(to: CGPoint(x: 32.79154905, y: -96.8022685))
        
    }

but we are trying not to hardcode and instead create a function that takes an array of coordinates like this:

 func create(coordinates: [CLLocationCoordinate2D]) {
        for coordinate in coordinates {
            path.move(to: CGPoint(x: coordinate.x, y:coordinate.y))//error
            path.addLine(to: CGPoint(x: coordinate.x, y: coordinate.y))//error
        }
    }

The issue is how to get the first coordinate in array for the "path.move" and then use the additional coordinates to use in the "path.addLine" part of function?

Answer 1

enumerate the array and test its index:

  for (index, coordinate) in coordinates.enumerated() {
        if index == 0 {
            path.move(to: CGPoint(x: coordinate.longitude, y:coordinate. latitude))
        } else {
            path.addLine(to: CGPoint(x: coordinate.longitude, y: coordinate.latitude))
        }
  }

also notice that CLLocationCoordinate2D does not have x nor y but longitude and latitude
