This practical, example-based article walks you through a couple of different approaches to calculating the average (the mean) of all elements in a numeric array (an array that contains only numbers) in Swift. No more wasting time;......

This practical, code-centric article will walk you through several different ways to calculate the sum of a numeric array (an array that only contains numerical elements) in Swift. Using the reduce() method You can use the reduce()......

Overview Swift provides several built-in array methods that can help you find the index of an element (when knowing its value or some of its characteristics) in a given array: firstIndex(of:): You can use this method to find the......

When developing applications with Swift, there might be cases where you need to reverse a given array, such as when you want to display an array of messages or comments in chronological order from newest to oldest (or vice versa). This......
