Swift Bitwise operators allow you to perform operations on the binary form of numbers. You can specify a binary literal by prefixing the number with 0b, so for example 0b110 is equivalent to the binary number 110 (the decimal number 6). Each 1 or 0 is a bit in the number. Bitwise NOT ~: var number...
