Before they start coding something, most programmers begin by creating a data flow diagram to know exactly how each piece of code is supposed to work (how it should behave). If the behavior of the application is not complicated, you do not have to sketch it (although it is a good habit, even with simple things), but with more complicated behavior, it is hard to properly code such flow.
iOS 10 offers many new features. One of them is CallKit, the framework which allows our application to seamlessly integrate with the user interface of a phone. CallKit may be used in applications to allow users to receive incoming calls and perform outgoing calls with the phone-provided UI. VoIP call can be muted or suspended. It is also possible to make video calls.
In iOS 10 we can use SFSpeechRecognizer API, which allows transcription in real-time or using pre-recorded audio files. The outcome of such transcription is not only a text, but also alternative interpretations of the audio, length of spoken words and level of accuracy of recognized words (range 0.0 - 1.0). API allows for the analysis of more than 50 languages. Using SFSpeechRecognizer API in an application is trivial, it boils down to four steps.
I would like you to get acquainted with a switch conditional statement in Swift, using the rubber duck method. I assume that you already know the concept of the switch statement, therefore, I will show you what is new in Swift.
Clean-swift architecture is very simple and does not require any additional libraries. It consists of 3 layers that nicely separate views from logic; the flow of information in clean-swift is unidirectional as shown in the image attached below. This means that if, for example, after pressing the button we have to change the value of text field, the information (after pressing the button) should go to interactor that will prepare the model and send it to presenter, which will “enhance” the text by setting the type of font, color, etc. and will pass it as new model to ViewController for displaying.
The new version of iOS introduces a number of changes concerning both local and server notifications. We can use a new framework, UserNotifications, which enables both delivering and handling notifications. New notifications allow you to add images (jpg, png, gif) and videos, and to perform other actions. Moreover, we can now use Notification Content Extension through which we can design the exact appearance of notification in our application.
Recently, the new 3.0 version of the Swift language has been presented. Some of the noticeable changes include modifications involving the removal of functions which have already been removed in Swift 2.2. Changes involving modernisation of the language are also present.
Introducing 10th version of iOS, Apple gave developers a new tool – UIViewPropertyAnimator. It enhances options of creating animation in our application. New options include stopping animation and resuming it (also with other time parameters), finishing animation at any time, reversing animation or moving it to any chosen moment, and many more. Another novelty is the fact that apart from previously used timing options of animation, such as EaseInEaseOut we now also have the ability to define our own time function based on checkpoints of cubic function.
Today, I will talk about one of the frameworks added in iOS 9: Core Spotlight . API allows you to add content to spotlight search engine, so that, for example, an application used for watching movies allows for adding movies, actors, directors and reacting if users select an item, so that we can move them to the desired location within the application.
