My app has been rejected twice because it crashed at launch. I’ve tested the app on both iPhone 4, iPhone 3Gs and an iPod Touch 1st gen. It runs flawlessly and doesn’t crash at any time.

My problem is that I cannot reproduce the crash, so how can I fix it?

The crash report from Apple states:

Any suggestions?

I’ve submitted a game a month ago running iOS 4.2 which got approved right away. Could this be an issue related to iOS 4.3?

Thanks

your game work on IOS 4.3 ?

there is some problem with Unity and 4.3 ...

**glenwn** · Posted: 08:31 AM 03-24-2011

Yes, it works perfectly. The first time I make a build there are thousands of warnings. If I build again all the warnings are gone. I have tried installing the game on about six different devices and it runs without any problems, but it crashes instantly on the review team's phones.

You may have to wait until Unity supports 4.3, there maybe something you can't see.

**glenwn** · Posted: 09:26 AM 03-24-2011

Yeah. I'll guess you are right. I just have to be patient

I'm not an expert in crash report, but something tells me that "Crashed Thread: 0" is something that are way out off my hands.

Thanks for your quick replies anyway

Hi do you have an EXec bad access when running with last version of Xcode ? (crash when launched by xcode, but then run with no bug if launch from device)

See this thread for more info : http://forum.unity3d.com/threads/80573-iOS-4.3

**danielsonchris** · Posted: 02:22 AM 03-25-2011

What version of Unity are you running?

**danielsonchris** · Posted: 03:42 PM 03-25-2011

Just as an additional note. It looks like Apple just released a new version of XCode 4.0.1 yesterday. That may or may not help anything...

**synapsemassage** · Posted: 03:14 AM 03-26-2011

I also experienced problems that are maybe related to yours. During development I always used to build with script call optimisations "slow and save" (player settings) and everything was running without any problems on every device but for release builds I switched to "fast and no exceptions" that gave me some EXC_BAD_ACCESS. EXC_BAD_ACCESS means usually that something is missing or cannot be found like empty variable/gameobject. Checking for this I found a script that missed an object. Weird that this wasn't catched earlier by the debugger.

**francksitbon** · Posted: 03:59 AM 03-26-2011

Is there any strong fps enhancement using fast but no exception in stead of slow and safe ?

**glenwn** · Posted: 08:16 AM 03-27-2011

Downgraded to iOS 4.2 and it got approved right away.

@francksitbon My experience tells me that there are little fps enhancement using fast but no exceptions.

@glenwn - interesting workaround downgrading to 4.2 SDK - I thought it was a submission requirement to build with the current version of the SDK.

I'm using SDK 4.3 with XCode 3. Just for comparison, when you were building with SDK 4.3 were you using XCode 3.x or XCode 4.x? -Thanks!

Me too....EXC_BAD_ACCESS (SIGBUS)

@sealiongames I've tried building for iOS 4.3 in both Xcode 3 and 4 with no luck using any of them. The app got rejected with the same error log on both of them.

**Minevr** · Posted: 11:06 PM 03-29-2011

Hi,
are you using any of third party libraries? There have been cases when using thumb-compiled third party libraries were causing random crashes. If you aren't using such library please submit a bugreport with repro case attached to it.
Thanks!

Unity 3.3 supports iOS SDK 4.3 (with Xcode 3.x) not worse than iOS SDK 4.2 (when setting iOS SDK version to "iOS latest" in Player Settings).

All the trouble reports for iOS SDK 4.3, which we received, were not caused by the iOS SDK version change. Top reasons for failures were (usually reported as EXC_BAD_ACCESS in Xcode):
- Using third party thumb-compiled libs (which are not supported by Unity).
- Using features that are not supported on iOS platform, like Terrain. (There is known issue with Unity Editor, which allows you to build project with unsupported features).
- User script problems, where scripts access uninitialized variables.

If you have problems other than mentioned above please report a bug with repro case attached to it.
Thanks!

apple rejected my build using iOS SDK 4.3 with Xcode 4.

I built the application again on iOS SDK 4.2 with Xcode 3.x and it got approved right away.

Something is wrong with Unity3D and iOS SDK 4.3 w/ Xcode 4
