Looping with Grace: Unveiling the 'each' Library for Swift

In the realm of Swift programming, looping through collections is a common chore. But who said chores can't be elegant and fun? Enter 'each', an open-source library on GitHub designed for Swift, aimed at offering a more concise and graceful way to loop through sequences like arrays, dictionaries, and sets.

Unwinding the Loop with 'each':

// Simple Looping
each(1...10) { number in
    print(number)
}

// Modifying Mutable Sequences
var numbers = [1, 2, 3, 4, 5]
each(numbers) { number in
    number *= 2
}
print(numbers) // Outputs: [2, 4, 6, 8, 10]

// Filtering Sequences
each(numbers) { number in
    if number % 2 == 0 {
        print(number)
    }
}
print(numbers) // Outputs: [2, 4, 6, 8]

Engage in the 'each' Loop:

1. Install each.
2. Integrate each into your Swift project.
3. Unroll the loops with each.

The Loop Deepens:

// Nested Looping
each(1...10) { outerNumber in
    each(1...10) { innerNumber in
        print("Outer Number: \(outerNumber), Inner Number: \(innerNumber)")
    }
}

// Utilizing Closures
each(1...10) { number in
    print(number * 2)
}

Moreover, 'each' extends its functionality to sorting and grouping elements within sequences, among other capabilities. A peek into the GitHub README reveals a wider horizon of features awaiting exploration.

A Loop Above the Rest:

'each' isn’t just a looping library; it’s a powerful ally to Swift developers. Its ease of use, potent functionality, and exceptional performance set it apart, making looping through sequences less of a routine and more of a breeze.
