[2017.3.0f3] iOS Build crashes all the time

Hi all,

Just upgraded to 2017.3.0f3, and our game now crashes on iOS all the time.Code builds and runs without any issues on 2017.2.0p4.

Some times, we get this EXC_BAD_ACCESS in ShouldUpdateTransformBefore (as shown in the attached pic).

Other times, we don't get any exception, but the game just freezes.

And the crash is at different times, some ties we get further along in the game initialization, some times is right from the stat.

Any idea what's causing this? And is there a workaround?

Thanks!

 

I got it today...while i update my Unity : 2017.2 -> 2017.3

 

Yeah. We gave up on 2017.3 until it gets stable. We found a lot of issues with 2017.3.

• Crash on iOS (mentioned on first post), random, 100% of the time.

• Building Asset Bundles, really slow, on 2017.2 takes us about 2-3 minutes, to build 180 MB in AssetBundles. . in 2017.3, it takes 1.5 hours.

• Really slow importing assets

• Every time the 2017.3 Editor receives focus, spends 5-10 seconds refreshing files. While test running the game, it becomes really annoying. We disabled automated refresh, and this fixed it, but then we had to press Command-R every time we had changes to source code.

Ultimately the crash / freeze on device 100% is what made 2017.3 unusable for us. We are back on 2017.2, and everything is moving smoothly..

 

Just wanted to second this - I'm getting the same EXC_BAD_ACCESS in ShouldUpdateTransformBefore error in cases where previously everything was working swimmingly. This seems limited to instances where I'm using ScrollRect.

EDIT: I'm on Unity 2017.3.0p1. Will try downgrading to 2017.2 - app icons fix be damned - and see if it fixes things.

EDIT: Downgraded to 2017.2 and the issue no longer occurs. Made absolutely no changes to the code, so this must be related to 2017.3.

 

+1 I've been experiencing the same issue. Will also try downgrading to 2017.2

 

Experiencing the same, something to do with unity UI. I haven't been able to find the specific reason.

 

Similar issue here.
The error happen when sending logs with unitywebrequest
The app crash because of that, didnt happened with 2017.1
Here are some logs of my crash, running 2017.3.0f3 on an iOS device (ipad)

I got this on 2017.3 as well

 

Could you please submit a bug-report, following the advice given in this document.

It's important that at least one person, who experiences this issue, reports it to Unity Technologies. Otherwise they're probably not going to fix it. Downgrading Unity is a temporary workaround, but if they don't have a bug-report, you might be stuck with that old version forever.

From past experience, Unity isn't looking for bugs on the forum, but they do look at the bug-reports submitted using their Bug Reporter Tool as described in the posted link.

 

I've experienced this problem as well. I'll try to make a bug report for this. Their bug report servers for project uploads are really slow. Last time a watered down project <20MB took close to 10 minutes to submit.

Same here

 

I'm getting the same crash. Crashes on startup and return from suspend sometimes. Can't really say how to reproduce it since it doesn't happen all the time. Started since 2017.1, same on 2017.1p1

 

Could you submit a bug-report as asked here?

 

Done, sent one today.

 

Got the same crash.

Hi,

Do you have a RectTransform with a scale = 0?

I have a feeling ..

No news on this, haven't gotten any response on my bug report either. Feels like this is a fairly usual crash on iOS and 2017.3.

 

I got this on 2017.3.0p1 + iOS 10.3.3.
But doesn't occur on 2017.3.0p1 + iOS 11.2.2.

 

Yup, happening here. 2017.3, ios 11.2.1

 

Same here, random BackgroundWorker (32): EXC_BAD_ACCESS error

 

I've been getting the same error on device only, happens at random times. I've been trying to pinpoint the problem for a few days but haven't had any success.

 

#meToo
2017.3.0p1 + iOS 10.3.3 iPhone6S plus

 

Just to add that, before I downgraded to 2017.2, the issue occurred on iPhone 6, iPhone X, and Ipad Air 1. In other words, I'm inclined to think it's not device-specific.

 

mee too, same crash!

 

Downgrading to 2017.2 worked for us.

submitted a bug report: https://fogbugz.unity3d.com/default.asp?986584_91sr34144jmcfca7

 

Just updated to 2018 beta and the game still crashes

 

I got a email from a guy from Unity that was working on it. Sent him my project so I guess he is investigating it. Hopefully it can be solved soon.

 

Same here...

 

Same here. And back to 2017.2.1p2 solved the problem.

 

Same here. Still happened with 2017.3.0p2

 

Bug report is up now guys:
https://issuetracker.unity3d.com/is...n-instantiating-gameobjects-into-a-scrollrect

 

Still having it everything is updated to the latest stable build but still
Any idea? Tips?

 

Hi, Same problem here, spent all night trying to find what causes the crashes before I found this thread, 2017.2. solved it for me too ! Thanks

 

I am having this issue as well

 

Anyone got any leads on this? Or found mitigations? Seems like there is something that triggers it. I suspect we may have the occasional scale of 0 in our scenes, or possibly camera positions with NaN in them.

 

By the look of things, this is caused by instantiating objects into a ScrollRect. You can mitigate either by downgrading to 2017.2 or by hardcoding ScrollRect contents.

 

I don't think I even have a ScrollRect

 

Still present in Unity 2018. I was only able to get around this by downgrading to 2017.2

 

Same here.
Unity version: 2017.3.0f3

I am changing the screen orientation in code, when I go from Portrait to Landscape I don't have problems, but when I go back I get the crash.

Image of stack trace attached.

 

Witch version you used? 2017.2.0 or 2017.2.1 ?

 

It works with both.

 

Same issue here for us, not good!

 

Hi guys, I have this problem and a huge performance drop on 2017.3.0f3. Have you experienced this too? As far as I can see, it is on the UI, the profile shows a bottleneck on UI methods:

https://forum.unity.com/threads/ui-...r-blames-ugui-rendering-updatebatches.514207/

Have any of you seen this? It completely blocked me from releasing a new version to iOs.

Thanks everyone.

 

We also encounter this issue with Unity 2017.3.0f3...

 

Just to chip in, I had a go at making sure no recttransforms ever had a scale of 0 and that their scale as uniform across the whole project. It may have removed some of the errors but it's still occurring 50% of the time. Using 2017.2.1p2 resolved for me

 

A bug report had already been filed some time ago and a fix is currently in review:

https://issuetracker.unity3d.com/is...n-instantiating-gameobjects-into-a-scrollrect

 

Damn. I was looking at info to upgrade to 2017.3, looks like Im staying 2017.2.
