Swift provide an in built function named as shuffle() to shuffle the elements of an array. This function takes a sequence or array and then shuffle the places of the elements present in the given array. Syntax func shuffle() Where this function does not take any parameter. Also it ... Read More

In Swift, super keyword in used to access or call the methods, properties, and initialisers of the superclass from the base class. Or we can say that super keyword add more functionality to the superclass by adding its own unique behaviour. You can use super keyword with class properties, methods, ... Read More

In Swift, static keyword is used to define or create type-level properties and method that only belongs to the class itself rather than to its instances. Or we can say that we can directly access the static properties and methods of a class with help of class itself instead of ... Read More

In Swift, to search elements in a set we can use either contains(_:) function or linear search. Both the methods efficiently search an element in a set. Lets discuss both the methods in detail along with examples. Method 1: Using contains(_:) Function Swift provide an inbuilt function named as contains() ... Read More

In Swift, we create a user defined function to rotate the elements of an array. In this function, first we find the total number of rotation and then rotate the array by the specified number of rotation. For example − Array = [3, 5, 2, 1, 7, 9] Rotation = ... Read More

In swift, a set is a unordered collection that only contain unique values. As we known that a set is an unordered collection so their is no direct way like an array to reverse the elements of the set. However you can reverse a set by converting it into an ... Read More

In Swift, linear search is the most easiest search algorithm. It is also known as sequential search because it check all the elements of the given array or sequence one by one. If the target element is found, then return the index of that array otherwise return element not found. ... Read More

Just like other programming languages Swift also supported two- dimensional array. A two dimensional array is known as an array of array that store same type of data in a tabular format. Or we can say 2-D array is an array which represent homogeneous data in rows and columns. ... Read More
