For the purposes of this exercise we will be working with the binary representation of two numbers. Firstly, the decimal number 171 is represented in binary as:

For the purposes of this exercise we will be working with the binary representation of two numbers. Firstly, the decimal number 171 is represented in binary as:

10101011

<tt>10101011</tt>

Secondly, the number 3 is represented by the following binary sequence:

Secondly, the number 3 is represented by the following binary sequence:

00000011

<tt>00000011</tt>

Now that we have two binary numbers with which to work, we can begin to look at the Swift bitwise operators:

Now that we have two binary numbers with which to work, we can begin to look at the Swift bitwise operators:

The Bitwise NOT is represented by the tilde character and has the effect of inverting all of the bits in a number. In other words, all the zeros become ones and all the ones become zeros. Taking our example 3 number, a Bitwise NOT operation has the following result:
