If your host app uses a UITabBarController, the StreamLayer Launch Button can overlap the tab bar. To prevent overlap, add a bottom offset to the overlay view container’s constraints (for example, 84 points). See PresentStreamSceneViewController.swift for the relevant function here.

Replace the following code in the demo app:

// Portrait
overlayVC.view.snp.remakeConstraints { [weak view] make in
   guard let videoPlayer = videoPlayer else { return }
   $0.top.equalTo(videoPlayer.view.snp.bottom).offset(-40)
   $0.left.right.bottom.equalTo(0)
}

with this updated version that adds a bottom offset:

// Portrait (with bottom offset)
overlayVC.view.snp.remakeConstraints { [weak view] make in
   guard let videoPlayer = videoPlayer else { return }
   $0.top.equalTo(videoPlayer.view.snp.bottom).offset(-40)
   $0.left.right.equalToSuperview()
   $0.bottom.equalToSuperview().offset(-84)
}
