Ok.. I followed the advice here: https://stackoverflow.com/questions/47788568/avplayer-is-unable-to-play-sound-in-device and after calling the function in episode didSet method (in PlayerDetailsView), it seems to be working. but I am curious if this is a hack or is that the right place to add this method

Ah awesome.. thanks for clarification.. I should stick to the pace of course rather getting ahead of myself. Thanks

ended up using a simple notification, but if you have a better idea I'd be happy hear it!

I used 'accessibilityViewIsModal = true' In PlayerDetailsView initializer (when the player opens up) Here's more info: https://developer.apple.com/documentation/objectivec/nsobject/1615089-accessibilityviewismodal

yes me too , u need to move this line self.view.layoutIfNeeded() to the end of the block of animation in minizePlayerDetails function and minizePlayerDetails function in MainTabBarController.swift file that will solve the pushing up when press Dismiss button but there is still small glitch of tabbar , if u solved it tell me pls .

minizePlayerDetails and maximizePlayerDetails functions

The problem arrises when calling layoutIfNeeded() before you call .identity on the tabBar transform. @objc func minimizePlayerDetails() { // the order of these calls prevents layout warnings maximizedTopAnchorConstraint.isActive = false bottomAnchorConstraint.constant = view.frame.height minimizedTopAnchorConstraint.isActive = true UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 0.7, initialSpringVelocity: 1, options: .curveEaseOut, animations: { self.tabBar.transform = .identity self.view.layoutIfNeeded() self.playerDetailsView.maximizedStackView.alpha = 0 self.playerDetailsView.miniPlayerView.alpha = 1 }) }
