  *(_:_:)

Declaration

Swift

  static 
 func 
 * 
 ( 
 lhs 
 : 
 Camera 
 , 
 rhs 
 : 
 Double 
 ) 
 -> 
 Camera

  
  
  +(_:_:)

Adds two values and produces their sum.

The addition operator ( + ) calculates the sum of its two arguments. For example:

You cannot use + with arguments of different types. To add values of different types, convert one of the values to the other value’s type.

  let 
 x 
 : 
 Int8 
 = 
 21 
 let 
 y 
 : 
 Int 
 = 
 1000000 
 Int 
 ( 
 x 
 ) 
 + 
 y 
 // 1000021

Declaration

Swift

  static 
 func 
 + 
 ( 
 lhs 
 : 
 Camera 
 , 
 rhs 
 : 
 Camera 
 ) 
 -> 
 Camera

Parameters

`lhs`	The first value to add.
`rhs`	The second value to add.

+=(_:_:)
Adds two values and stores the result in the left-hand-side variable.
Declaration
Swift

static func += ( lhs : inout Camera , rhs : Camera )
Parameters

lhs

The first value to add.

rhs

The second value to add.

  
  
  -(_:_:)

Subtracts one value from another and produces their difference.

The subtraction operator ( - ) calculates the difference of its two arguments. For example:

You cannot use - with arguments of different types. To subtract values of different types, convert one of the values to the other value’s type.

  let 
 x 
 : 
 UInt8 
 = 
 21 
 let 
 y 
 : 
 UInt 
 = 
 1000000 
 y 
 - 
 UInt 
 ( 
 x 
 ) 
 // 999979

Declaration

Swift

  static 
 func 
 - 
 ( 
 lhs 
 : 
 Camera 
 , 
 rhs 
 : 
 Camera 
 ) 
 -> 
 Camera

Parameters

`lhs`	A numeric value.
`rhs`	The value to subtract from `lhs` .

-=(_:_:)
Subtracts the second value from the first and stores the difference in the left-hand-side variable.
Declaration
Swift

static func -= ( lhs : inout Camera , rhs : Camera )
Parameters

lhs

A numeric value.

rhs

The value to subtract from lhs .

  
  
  /(_:_:)

Declaration

Swift

  static 
 func 
 / 
 ( 
 lhs 
 : 
 Camera 
 , 
 rhs 
 : 
 Double 
 ) 
 -> 
 Camera

==(_:_:)
Returns a Boolean value indicating whether two values are equal.

Equality is the inverse of inequality. For any values a and b , a == b implies that a != b is false .
Declaration
Swift

static func == ( a : Camera , b : Camera ) -> Bool
AnimatableData

Parameters

`center`	The center coordinate of the camera.
`heading`	The heading of the camera in degrees.
`tilt`	The tilt of the camera in degrees.
`roll`	The roll of the camera in degrees.
`range`	The distance from the camera to the center coordinate in meters.
`fieldOfView`	The field of view of the camera.
`altitudeMode`	The altitude mode of the camera. Note that `altitudeMode` is only relevant for `flyCameraTo` and `flyCameraAround` animations.
