Sorting a Nested String Array by a Corresponding Numbered Array in Swift

Sorting arrays can be a tricky task, especially when you have a nested string array that cannot be sorted alphabetically. This article will guide you through how to sort such an array using a corresponding numbered array to maintain the relationships between elements.

Understanding the Problem

Imagine you have a nested string array that looks like this:

Step-by-Step Solution

To solve this, we will take advantage of Swift's powerful array sorting capabilities. Here’s a breakdown of the procedure:

Step 1: Sorting the Nested String Array

You can get an index from the nestedArray and sort using the values from the numberArray. Here's how you can achieve this:

Conclusion

Sorting a nested string array based on a corresponding numbered array in Swift can be a smooth process when you utilize proper indexing. This method ensures that both arrays are sorted according to the right relationships without losing their connections.

Utilize this technique whenever you find yourself faced with similar sorting challenges in your Swift applications. Happy coding!
