I’m getting Auto Layout constraint conflict warnings related to AVPlayerController in my tvOS project.

This issue can be reproduced in an empty tvOS project either by simply using an AVPlayerViewController as a initial view controller or by presenting it.

tvOS 26.2

Simple empty project with only one controller:

import UIKit
import AVKit

class PlayerViewController: AVPlayerViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
    }
}

After presenting that view controller, the following Auto Layout constraint conflict warnings appear in the console:

Unable to simultaneously satisfy constraints.
	Probably at least one of the constraints in the following list is one you don't want. 
	Try this: 
		(1) look at each constraint and try to figure out which you don't expect; 
		(2) find the code that added the unwanted constraint or constraints and fix it. 
(
    "<NSLayoutConstraint:0x60000212f5c0 UIStackView:0x103222520.width >= 217   (active)>",
    "<NSLayoutConstraint:0x60000212f610 H:|-(>=95)-[UIStackView:0x103222520]   (active, names: '|':UIView:0x103216630 )>",
    "<NSLayoutConstraint:0x60000212f660 UIStackView:0x103222520.trailing == UIView:0x103216630.trailing - 95   (active)>",
    "<NSLayoutConstraint:0x60000212f7a0 H:|-(0)-[UIView:0x103216630]   (active, names: '|':_AVFocusContainerView:0x10333aea0 )>",
    "<NSLayoutConstraint:0x60000212f7f0 UIView:0x103216630.trailing == _AVFocusContainerView:0x10333aea0.trailing   (active)>",
    "<NSLayoutConstraint:0x6000021309b0 '_UITemporaryLayoutWidth' _AVFocusContainerView:0x10333aea0.width == 0   (active)>"
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x60000212f5c0 UIStackView:0x103222520.width >= 217   (active)>

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.

How can I fix this issue? Thanks.

Thanks for the post and description. Unfortunately I don’t see the code or how you are presenting the AVPlayerViewController but this is very interesting as if you look at the documentation doesn't support subclassing AVPlayerViewController. From the official docs:

The framework doesn't support subclassing AVPlayerViewController. Please read the note on the documentation:

https://developer.apple.com/documentation/avkit/avplayerviewcontroller

Can you provide more information? My recommendation is to download this sample and see how is been build https://developer.apple.com/documentation/avkit/playing-video-content-in-a-standard-user-interface
