por Today we talk to you about what is casting in Swift. To develop an app, you need to know the basic concepts related to programming, since you may need them in your development projects.
If you want to learn more about the programming language designed by Apple, We invite you to read our post What is Swift and what are its main features?, where we mention the general aspects of this language that, currently, is one of the most used.
What is casting in Swift?
In general terms, when we ask what casting is in Swift, we are asking how to cast one type of data to another. This means that the action of casting refers to convert one type of data to another type of data.
For example, Imagine that you want to multiply a type of data integrate with a float; At first, you can’t do it because they are two different types of data, but you can do it through the cast action.
How to cast in Swift?
Now that you know what casting is in Swift, we can tell you how to perform this action. The first thing you should know about how to cast in Swift is that the keyword for this is “cast”.
Following the example that we mentioned before, related to multiplying two values that correspond to different data types in Swift, you could do it in the following way:
Something you should know about casting in Swift is that It all depends on the process you want to carry out, that is, what type of data you want to convert, since this changes the code you must write.
Where to continue?
After telling you what casting is in Swift and a possible case where you can implement this action, You probably want to know more concepts and aspects related to the entire process of developing and designing a mobile application. If you have a particular interest in entering this field of work, we invite you to learn all the knowledge you need for this with our Full Stack Mobile App Development Bootcamp.
