Setup application in code

MainTabBarController file

override func viewDidLoad() {
        super.viewDidLoad()
        
        searchVC.tabBardelegate = self
        
        var library = Library()
        library.tabBarDelegate = self
        let hostVC = UIHostingController(rootView: library)
        hostVC.tabBarItem.image = #imageLiteral(resourceName: "library")
        hostVC.tabBarItem.title = "Library"

        viewControllers = [
            hostVC, 
            generateViewController(rootViewController: searchVC, image: "magnifyingglass", title: "Search")
        ]
    }

UIKit and SwiftUI

There are two main screens: Search and Library. Search screen made with UIKit, and Library made with SwiftUI. To make work them together in func viewDidLoad() of MainTabBarController (which is main controller for both views) I used UIHostingController().

var library = Library()
library.tabBarDelegate = self
let hostVC = UIHostingController(rootView: library)

Player

TrackDetailView file

Track player made with AVKit

let player: AVPlayer = {
        let avPlayer = AVPlayer()
        avPlayer.automaticallyWaitsToMinimizeStalling = false
        return avPlayer
 }()

func awakeFromNib() anstead of func viewDidLoad(), because TrackDetailView representation made with xib file.

override func awakeFromNib() {
        super.awakeFromNib()
}

Gestures

private func setupGestures() {
        
        miniTrackView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleTapMaximized)))
        miniTrackView.addGestureRecognizer(UIPanGestureRecognizer(target: self, action: #selector(handlePan)))
        addGestureRecognizer(UIPanGestureRecognizer(target: self, action: #selector(handleDismissalPan)))
 }

Animation

If you press play or pause you'll see that track image changes size with animation.

private func enlargeTrackImageView() {
    UIView.animate(withDuration: 1, delay: 0, usingSpringWithDamping: 0.5, initialSpringVelocity: 1, options: .curveEaseInOut, animations: {
       self.trackImageView.transform = .identity
     }, completion: nil)
}
    
private func reduceTrackImageView() {
   UIView.animate(withDuration: 1, delay: 0, usingSpringWithDamping: 0.5, initialSpringVelocity: 1, options: .curveEaseInOut, animations: {
     let scale: CGFloat = 0.8
     self.trackImageView.transform = CGAffineTransform(scaleX: scale, y: scale)
    }, completion: nil)
}

Images and SDWebImage Library

SDWebImage provides an async image downloader with cache support.

miniTrackImageView.sd_setImage(with: url, completed: nil)
trackImageView.sd_setImage(with: url, completed: nil)
