SKView warning logs

Question

When running my SwiftUI & SpriteKit app, I get the following messages in the logs:

2019-11-18 21:58:57.631912+0000 PixelBattles[2812:1215803]

SKView: ignoreRenderSyncInLayoutSubviews is NO. Call _renderSynchronouslyForTime without handler

What am I doing wrong to receive this log, and should I worry about it? Could it be a bug?

Could it be that SwiftUI cannot figure out how to do the layout for an SKView?

Major edit:

^{If you need code, you can see it in the previous edits. Below I state why I don't think it is any longer relevant.}

I have sent Apple some feedback (FB7456217). I have removed the code, as I no longer suspect it is an issue to do with my code. I created a blank game project, no SwiftUI, and still got the same warning log instantly.

So even with the default project template, the log still appeared for device and simulator. I will update on this issue if I get a useful response.

I still haven't heard anything back - has anyone got any new information since when I posted this over half a month ago? I still have these warnings!

Answer 1

This is Apple's response to this issue:

Hi! You don't really need to fix that. That's a log message that was left by mistake in SpriteKit framework. It was removed and will no longer appear in the future SpriteKit versions. Thanks!

Thank you! They never got back to me, and it was not marked as duplicate either. I have now closed the issue. – Afghan

Answer 2

just figured this out for myself.

In your code change

if let scene = SKScene(fileNamed: "GameScene")

to

if let scene = GameScene(fileNamed: "GameScene")

I believe you'll also get this warning if you have UIKit subviews of the SKView.

Is it a problem to use UIKit inside of an SKView or can the warning be ignored? – Biology

Doesn’t seem to cause any issues, but who knows. – Genaro
