How to change the font of UIButton with Swift?
In Swift, this is very easy to change the font of a button. You can use the titleLabel property of the button which is of type UILabel class. This property provides another property called font to apply the desired font. Let’s see some examples of changing the font. We will follow the below steps to change the font of a button − Step 1 − Initially, we will do the basic setup with button creation and customization. Step 2 − In this step, we will change the system font with size and weight. Step 3 − In this ...
Read MoreSwift Program to print the right diagonal matrix
A matrix is an arrangement of numbers in rows and columns. Matrix can be of various type like square matrix, horizontal matrix, vertical matrix etc. So here we print the right diagonal of square matrix. Square matrix is a matrix in which the number of rows and columns are same. For example 3x3, 5x5, 7x7, etc. In this article, we will learn how to write a swift program to print the right diagonal matrix. Algorithm Step 1 − Create a function. Step 2 − Run for-in loop to iterate through each element of the matrix. Step 3 − Check for ...
Read MoreSwift Program to print the left diagonal matrix
In this article, we will learn how to write a swift program to print the left diagonal matrix. A matrix is an arrangement of numbers in rows and columns. Matrix can be of various type like square matrix, horizontal matrix, vertical matrix etc. So here we print the left diagonal of square matrix. Square matrix is a matrix in which the number of rows and columns are same. For example 3x3, 5x5, 7x7, etc. Algorithm Step 1 − Create a function. Step 2 − Run for-in loop to iterate through each element of the matrix. Step 3 − Check ...
Read MoreSwift Program to Check whether a number is a Perfect Cube or not
A number is a perfect cube if the result of the three time multiplication of a whole number is the number itself. For example: number 5 is a per Number = 125 125 = 5*5*5 Here 125 is a perfect cube. Number = 98 Here 98 is not a perfect cube. In this article, we will learn how to write a swift program to check whether a number is a perfect cube or not. Method 1: Using user defined function To check if the given number is a perfect cube or not, we create a function that check each number ...
Read MoreSwift Program to Check if the given number is Perfect number or not
A perfect number is a positive number that is equal to the sum of its factors, excluding the number itself. For example − Number = 6 Proper divisors = 1, 2, 3 Hence, 6 is the perfect number because the sum of its divisors is 6(1+2+3) Number = 10 Proper divisors = 1, 2, 5 Hence, 10 is not a perfect number because the sum of its divisors is 8(1+2+5) In this article, we will learn how to write a swift program to check if the given number is a perfect number or not. Algorithm Step 1 − Create ...
Read MoreSwift Program to calculate the sum of rows of matrix elements
A matrix is an arrangement of numbers in rows and columns. Matrix can be of various type like square matrix, horizontal matrix, vertical matrix etc.In this article, we will learn how to write a swift program to calculate the sum of rows of matrix elements. Here we are using the following methods to find the sum of the rows elements − Using nested for-in loop Using in-built function Method 1: Using nested for-in loop Here we use nested for-in loop to find the sum of rows of matrix elements. Algorithm Step 1 − Create a function. Step 2 ...
Read MoreSwift Program to Calculate the Sum of Matrix Elements
A matrix is a rectangular array of numbers. Or we can say that a matrix is an arrangement of numbers in rows and columns. Matrix can be of various type like square matrix, horizontal matrix, vertical matrix etc. In this article, we will learn how to write a swift program to calculate the sum of matrix elements. So here, using the following methods we calculate the sum of matrix elements. Sum of square matrix elements Sum of any matrix elements For example, we have the following matrix − $\mathrm{Matrix\:=\:\begin{bmatrix}1 & 4 & 5 & 6ewline4 & 7 ...
Read MoreSwift Program to calculate the sum of columns of matrix elements
A matrix is an arrangement of numbers in rows and columns. The matrix can be of various types like square, horizontal, vertical, etc. In this article, we will learn how to write a swift program to calculate the sum of columns of matrix elements. Here we are using the following methods to find the sum of the column’s elements − Using a nested for-in loop Using in-built function Method 1: Using nested for-in loop Here we use a nested for-in loop to find the sum of columns of matrix elements. Algorithm Step 1 − Create a function. Step ...
Read MoreSwift program to check if string is pangram or not
Pangram string is a string that contains all the English alphabet. For example − String = “The quick brown fox jumps over the lazy dog” Here the string is a pangram string which contains all the alphabetical characters from a to z in it. String = “ Hello! Swati how are you?” Here the string is not a pangram string because it does not contain all the 26 alphabetical characters from a to z. In this article, we will learn how to write a swift program to check if a string is pangram or not. So to check if the ...
Read MoreSwift Program to check whether a given string is Heterogram or not
Heterogram string is a string in which no alphabet occurs more than once. For example, “Sky with cloud” is a heterogram because in the string each alphabet occurred only once. Whereas “colorful balloons” is not a Heterogram because in the string some alphabet like o, u, l, etc appears more than once. Here we will execute different examples that will check whether the given string is heterogram or not using swift programming language. Algorithm Step 1 − Create a function. Step 2 − Remove the white space from the string. Step 3 − Create a separate array to ...
