In Swift, you can use a for loop to repeat code. For example, let’s use a for loop to calculate the sum from 0 to 10: Output: Loops are extremely common in Swift and other programming languages. As you can imagine, when working with data, you need to be able to repeatedly perform the same […]

In Swift, you can use the switch statement to turn lengthy if-else statements into more concise and structured expressions. For example, take a look at this if-else statement. There is a lot of repetition and the code is quite long and somewhat verbose. In this case, you can tidy up the code by replacing the

In Swift, you can use an if-else statement to let your program make decisions. For example, let’s check if a person can drive based on their age: This results in the following output in the console: If-else statements are everywhere. They are the basic building blocks of programming. With if-else statements, you can start implementing

In Swift, there are three logical operators: &&, ||, and !. Here is a table that describes these operators: Operator Name Description Example && Logical AND operator. If and only if both the operands are true, the condition is true. true && false = false || Logical OR Operator. If either one of the two

In Swift, you can compare values using the comparison operators, such as the greater-than operator. For example, let’s check if 1 is less than 2: Output: Here is a table of all the comparison operators in Swift: Operator Name Description == equals Checks if two values are equal to one another. != not equal Checks

In this chapter, you are going to learn the basic math operators in Swift. The four common math operators in Swift are: For example, let’s perform some basic maths with these operators and store the results into variables: In this guide, you are going to learn how to do basic math in Swift. If you

In Swift, each variable/constant holds a value that represents some data type. There are lots of data types in Swift. As a beginner, it is important to learn these 5 basic data types first: Here are some examples of variables and constants that represent different data types: In this article, we are going to take

In Swift, a variable represents a value that can be changed later on. The idea of a variable in programming is the same as variables in math. To create a variable in Swift, use the var keyword. For instance, let’s create an integer variable that represents the number 10: A constant is a value that

To create an iOS app, you need to install an app called Xcode on your Mac. Xcode is a code editor where you write your iOS programs and run them. In this chapter, you are going to learn how to install Xcode, create a program file, and run the program. Because this is a beginner-level

So you want to become an iOS developer? It is a great choice! Developing iOS apps is an in-demand skill that is still definitely worth learning and is going to be such for a long time. However, building apps takes a lot of time. Probably a lot more than you thought. An integral part of
