I'm having problems trying to override non-class members but I get the error: "'override' can only be specified on class members".
How can I get around this?
override func ^(lhs: Int, rhs: Int) -> Int {
return Int(pow(Double(lhs), Double(rhs)))
}
I thought it would work OK, but I didn't expect an error to come up!
You cannot use override
in only file-scoped place. It uses within class scope.
Don't use ^
sign to make new function as you want. Here below is description of original function ^
:
/// Returns the result of performing a bitwise XOR operation on the two given
/// values.
///
/// A bitwise XOR operation, also known as an exclusive OR operation, results
/// in a value that has each bit set to `1` where *one or the other but not
/// both* of its arguments had that bit set to `1`. For example:
///
/// let x: UInt8 = 5 // 0b00000101
/// let y: UInt8 = 14 // 0b00001110
/// let z = x ^ y // 0b00001011
/// // z == 11
///
/// - Parameters:
/// - lhs: An integer value.
/// - rhs: Another integer value.
public static func ^ (lhs: Int, rhs: Int) -> Int
