A stack is a data structure which works on LIFO(last in first out) principle. It is used to store and manage data where the recently added item is the first one to be removed from the stack. Stack support the following operations − Push − It is used to add elements to the stack. So in Swift, we achieve push operation by the append() method. Syntax func push(_ items: T) { item.append(items) } Here, the append() function pushes a new element in the item stack. Pop − It is used to remove ... Read More
In Swift, sorting of a string means arranging the characters of the string in the specified order either in ascending or descending order. For example − Input: String = "color of the bird is pink" Output:" bcdefhiiiklnoooprrst" Here, the resultant string is sorted in ascending order. So to sort a string Swift provides an inbuilt function named sorted() function. This function returns a sorted string in which the characters of the string are stored in either ascending or descending order. This function can be defined in two types with and without parameters. ... Read More
In Swift, we can adjust the size of the string by trimming some specified number of characters from both sides of the string. Or we can also trim the extra whitespaces which we do not want from both sides of the original string using the following methods. Method 1: Trim a string from the both sides To trim a specified number of characters or a substring from both sides of the string we create a user-defined function which takes an input string and the length of the characters which we wanted to remove from both sides of the original ...

In Swift, we can adjust the size of the string by trimming some specified number of characters from the left side of the string. Or we can also trim the extra whitespaces which we do not want on the left side of the original string using the following methods. Method 1: Trim a string from the left side To trim a specified number of characters or a substring from the left side of the string we create a user-defined function which takes an input string and the length of the characters which we wanted to remove from the left side ...

In Swift, we can adjust the size of the string by trimming some specified number of characters from the right-hand side of the given string. Or we can also trim the extra whitespaces which we do not want on the right-hand side of the given string using the following methods − Method 1: Trim a string from the right side To trim a specified number of characters or a substring from the right side of the string we create a user-defined function which takes an input string and the length of the characters which we wanted to remove ...

Fahrenheit is the commonly used temperature-measuring unit. In this scale, the freezing point and boiling point of the water are 32 degrees and 212 degrees. Whereas Celsius is also a temperature-measuring scale. In the Celsius scale, the freezing point and the boiling point of the water are 0 degrees and 100 degrees. So in Swift, we can convert Celsius to Fahrenheit using the following methods − Using Formula Using converted() method Method 1: Using Formula We can easily convert Celsius to Fahrenheit using the mathematical formula. It is the easiest way to convert Celsius to Fahrenheit. Syntax ... Read More

In Swift, a string is a sequence of characters. So a string can contain small and larger words. Hence using the following methods we can find the largest word in the string. Using component() method Using user-defined method Example Input String: "Rabbit run fast" Output String: "Rabbit" Here, the largest word among all the given words in the string is “Rabbit”. Method 1: Using component() method The components() method is used to create an array of substrings from the given string, where each substring is separated by the specified separator. So here we use the components(separatedBy:.whitespaces) method ... Read More
Tween.js is a JavaScript library that is mainly used when we want to tween or animate an HTML5 or JavaScript property. It can work standalone as well as when integrated with Easel.js. In this tutorial, we will learn how we can make use of Tween.js with the help of a few examples. Before we go on to the main example, let's first discuss a few simple tweens so that when we use them in the main example, you don't get overwhelmed. Simple Tween In this tween, we will tween the alpha property of the target from 0 to 1 for ... Read More
A password is a combination of various characters of a specified length and is used to authenticate or gain access to the system or login to an account. It is designed for security purposes and ensures that only an authorized user can access or log in to the specific account. It is important to select a strong password so that other people cannot crack it. It is generated according to the following conditions − Contains at least one uppercase letter. Contains at least one lowercase letter. Contains at least one number. Length must be 8 characters Contains at ... Read More
