Why a call could not produce its normal result.

Members

!=(_:_:) ( lhs : Self , rhs : Self ) → Bool functionstatic ¶ functionstatic ¶ !=(_:_:)

Inherited from Equatable.!=(_:_:)

Returns a Boolean value indicating whether two values are not equal.

Inequality is the inverse of equality. For any values a and b, a != b implies that a == b is false.

This is the default implementation of the not-equal-to operator (!=) for any type that conforms to Equatable.

description : var description: String property [source] ¶ property [source] ¶ description: 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.
