Bubble Animation in SwiftUI With AVKit | by Abigail De Micco | Mar, 2022

Animation is without doubt one of the strongest solution to carry out communication. From TV ads to primary smartphone apps, they’re extensively used, even when we don’t discover them.

These days, they’re completely built-in into our purposes as they’re utilized by builders to reinforce the consumer expertise. Animations are certainly helpful as a type of suggestions that makes clear that an motion has been acknowledged by the system. The massive benefit (and likewise drawback) is actually to draw the consumer’s consideration, so you need to watch out in utilizing them.

Via this text, we’ll create a easy and colourful interface to take your first steps on this unbelievable world.

Let’s begin!

There are 3 issues to deal with: the circles, the animation and the background.

In a ZStack, we set up the variety of circles we wish to seem on the display screen. In our case, there are 50. Then we are saying that we randomly need the colours of the circles to maneuver in a spread between shades of purple, inexperienced and blue.

Of those coloured circles, we wish the underside circle to be lightened by the highest layer [line 14].
After that, we arrange the animation. We would like the circles to get greater and smaller by performing a small bounce [line 15], we wish it to repeat ceaselessly [line 16] going at a sure velocity [line 17] and with a sure delay between one circle and one other [line 18 ].

Within the remaining traces, we set up the scale of the circles by saying that we wish them to zoom in a random vary inside a sure area on the display screen and this should occur at each begin.

Transferring on to the background, we are able to select one of many predefined colours or create a brand new one. Let’s create a brand new one that we’ll name rouge. We are going to select its variation of purple, inexperienced and blue [line 5].

We are going to make this shade fill your complete display screen by means of .ignoresSafeArea() [lines 35–38]

Now we are able to combine some stress-free music to create an exquisite environment.

To begin with, we have to add a monitor as an asset, and we are able to do it just by dragging it within the respective part.

NB: At all times take note of copyright, use websites like Pixabay to obtain free music to make use of in your undertaking.

[Line 2, 6] Now we are able to import AVKit and set a brand new variable naming it as audio.

Then we go on the finish of the ZStack and enter the onAppear, indicating that the music must play on startup.

[Line 3–5] So, we create a brand new variable (tune) to which we affiliate the monitor title as it’s known as within the property after which we set the audio participant (audio) by specifying the tune and its file kind.

And we’re completed! Congratulations!

Right here’s the whole code:
