Structure

# CGPoint

A structure that contains a point in a two-dimensional coordinate system.

## Topics

### Creating Point Values

`init(x: Double, y: Double)`

Creates a point with coordinates specified as floating-point values.

`init(x: Int, y: Int)`

Creates a point with coordinates specified as integer values.

`init(x: CGFloat, y: CGFloat)`

Creates a point with coordinates specified as `CGFloat` values.

### Special Values

`static var zero: CGPoint`

The point with location `(0,0)`.

`init()`

Creates a point with location `(0,0)`.

### Geometric Properties

`var x: CGFloat`

The x-coordinate of the point.

`var y: CGFloat`

The y-coordinate of the point.

### Transforming Points

`func applying(CGAffineTransform) -> CGPoint`

Returns the point resulting from an affine transformation of an existing point.

### Alternate Representations

`var dictionaryRepresentation: CFDictionary`

Returns a dictionary representation of the specified point.

`init?(dictionaryRepresentation: CFDictionary)`

Creates a point from a canonical dictionary representation.

`var debugDescription: String`

A textual representation of the point’s coordinate values.

`var customMirror: Mirror`

A representation of the point’s structure and display style for use in debugging.

`var customPlaygroundQuickLook: PlaygroundQuickLook`

A representation of the point for use in Playgrounds.

Deprecated

### Comparing Points

`func equalTo(CGPoint) -> Bool`

Returns whether two points are equal.

## Relationships

### Geometric Data Types

`struct CGFloat`

The basic type for floating-point scalar values in Core Graphics and related frameworks.

`struct CGSize`

A structure that contains width and height values.

`struct CGRect`

A structure that contains the location and dimensions of a rectangle.

`struct CGVector`

A structure that contains a two-dimensional vector.

`struct CGAffineTransform`

An affine transformation matrix for use in drawing 2D graphics.
