how much wood could a woodchuck chuck if a woodchuck could chuck wood in swift

Here's an implementation of a function in Swift that calculates an estimate of how much wood a woodchuck could chuck if it could chuck wood:

main.swift
func woodChuckChuckEstimate(_ chuckFactor: Int) -> String {
    if chuckFactor < 1 {
        return "Invalid Chuck Factor"
    }
    
    var totalChuckableWood = 0
    for num in 1...chuckFactor {
        totalChuckableWood += num * 2
    }
    
    let resultString = "A woodchuck could chuck approximately \(totalChuckableWood) cubic inches of wood if it could chuck wood!"
    return resultString
}

// Example usage
let estimate = woodChuckChuckEstimate(10)
print(estimate)

The function takes in a chuck factor, which is an integer value that represents how many times a woodchuck can chuck wood in one day. The function uses a for-loop to calculate the total amount of wood that can be chucked by the woodchuck based on the chuck factor. Finally, the function returns a string with the estimate of the amount of wood that the woodchuck can chuck in cubic inches.

Note that this estimate is not based on actual scientific research, but rather on a popular tongue-twister.
