Question

How to check if a point is inside a rectangle in Swift

Answer 1

import Foundation

struct Point {
    var x: Double
    var y: Double
}

struct Rectangle {
    var topLeft: Point
    var bottomRight: Point
}

func isPointInsideRectangle(_ p: Point, in rect: Rectangle) -> Bool {
    return p.x >= rect.topLeft.x && p.x <= rect.bottomRight.x &&
           p.y >= rect.topLeft.y && p.y <= rect.bottomRight.y
}

let rect = Rectangle(topLeft: Point(x: 0.0, y: 0.0), bottomRight: Point(x: 7.0, y: 7.0))
let point = Point(x: 3.0, y: 2.0)

if isPointInsideRectangle(point, in: rect) {
    print("The point is inside the rectangle.")
} else {
    print("The point is outside the rectangle.")
}



/*
