create a bitset in swift

To create a bitset in Swift, you can use the built-in UInt (unsigned integer) data type. Each bit of a UInt represents a binary value of either 0 or 1. You can use boolean operations to manipulate the binary values of the bits.

Here's an example of how to create a bitset in Swift:

main.swift
var bitset: UInt = 0b1010_0101 // Initial bitset value: 0xA5

// Bit operations:
bitset &= ~(1 << 3) // Set the 4th bit to 0 (0xA1)
bitset |= (1 << 6) // Set the 7th bit to 1 (0xE1)
bitset ^= (1 << 1) // Toggle the 2nd bit (0xE3)
let isSet = (bitset & (1 << 5)) != 0 // Test if the 6th bit is set

print(bitset) // Output: 227
print(String(bitset, radix: 2)) // Output: 11100011
print(isSet) // Output: true
408 chars
12 lines

In this example, we start with a UInt value of 0b1010_0101 (or 0xA5 in hexadecimal). We manipulate the bits using bitwise boolean operators (&, |, and ^), and we test if a specific bit is set using a bitwise AND operator (&).

You can also use binary literals (e.g., 0b0000_0001) to assign bit values directly in your code.
