A textual representation of this instance.
Calling this property directly is discouraged. Instead, convert an
instance of any type to a string by using the `String(describing:)`
initializer. This initializer works with any type, and uses the custom
`description` property for types that conform to
`CustomStringConvertible`:
struct Point: CustomStringConvertible {
let x: Int, y: Int
var description: String {
return "(\(x), \(y))"
}
}
let p = Point(x: 21, y: 30)
let s = String(describing: p)
print(s)
// Prints "(21, 30)"
The conversion of `p` to a string in the assignment to `s` uses the
`Point` type's `description` property.
Creates an instance initialized to the specified floating-point value.
Do not call this initializer directly. Instead, initialize a variable or
constant using a floating-point literal. For example:
let x = 21.5
In this example, the assignment to the `x` constant calls this
floating-point literal initializer behind the scenes.
- Parameter value: The value to create.
Creates an instance initialized to the specified integer value.
Do not call this initializer directly. Instead, initialize a variable or
constant using an integer literal. For example:
let x = 23
In this example, the assignment to the `x` constant calls this integer
literal initializer behind the scenes.
- Parameter value: The value to create.
