[2017.3.0f3] iOS Build crashes all the time

AlienMe · December 20, 2017, 9:22pm

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

AlienMe · December 22, 2017, 3:32pm

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

Fonserbc · December 30, 2017, 12:56pm

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

Peter77 · January 1, 2018, 1:25pm

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.

qoobit · January 2, 2018, 3:34am

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

Zilk · January 3, 2018, 11:49am

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

Peter77 · January 3, 2018, 11:54am

Could you submit a bug-report as asked here ?

Zilk · January 3, 2018, 2:27pm

Done, sent one today.

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.
