por Today we talk to you about What are they closures in Swifta language that was designed by Apple and was presented to the public on June 2, 2014.
In case you want to know about other programming resources and functions with this Apple language, in addition to what they are closures in Swift, We recommend that you go to consult the section Mobile App Development from our blog; There you will find a lot of valuable information to answer your questions regarding programming with Swift.
What are closures in Swift?
Closures, also known in English as closures in Swift, they refer to code fragments that perform a task. In Apple terms, the closures They are considered blocks that are autonomous in functionality and that, in addition, can be “passed” and used in our code. This means that they can be “passed” and invoked in places other than their implementation.
In programming languages such as C and Objective-C, there are elements called blocks or blocks which are similar to closures in Swift. In Kotlin it is also possible to find a similarity to the closureswhich is the so-called lambda, which is a way of representing a function.
What are closures for in Swift?
After knowing what they are closures In Swift, the question may arise as to what they are for. Broadly speaking, the so-called closures in Swift are fragments that They allow you to capture and store references to any variable or constant of the context in which they are defined.
How to declare a closure in Swift?
After knowing what they are closures in Swift and what they are for, it is appropriate to also talk about how these code blocks are declared. In summary, we can say that the declaration of the composition of a closure or closure in Swift is done as follows:
{ (inputparameters) -> ReturnType in
code
}
This means that, to declare a closure or closure In Swift, you must set some input parameters and the return type in.
Where to continue?
Now that you know more about what they are closures in Swift, You surely want to continue learning about other concepts related to application development. Therefore, it is important that you know that at we are very aware that the topics that are related to the development of applications, both for mobile and desktop devices, can be complicated to understand and that these are learned, mainly, by putting them into practice. practice. So, to help you in your training process in the field of Mobile development, we have the Full Stack Mobile App Development Bootcamp at your disposal.
With this bootcamp we intend to offer you the opportunity to start your training process in mobile application development alongside professionals with several years of experience in this field of work in the IT sector. Likewise, with our teaching method inspired by the methodology hands onwhich focuses on combining theoretical aspects with practice to strengthen knowledge, we entrust ourselves with the task of helping you learn each topic as easily as possible.
For this reason, with this bootcamp, our goal is for you to learn all the fundamental aspects of Mobile development and design in just a few months and, in this way, you can focus on working on something that you truly like. This is how you will be able to learn fundamental information about what the cross-platform application development processes are like, as well as what the fundamentals are for designing for both iOS and Android and a wide variety of application design guidelines, in addition to several of the languages. essential programming.
