Mobile [5.4B10] iOS and general - 7 problems (3 solved)

Hello everyone!
When building for iOS, i notice two things:
- The build size is about twice as big as the Unity 5.2.2 version.
- Building the project takes much longer than it takes using Unity 5.2.2.

Also, there is an error showing up when trying to run it on a device via Xcode:
"
ld: '[path to build]/Libraries/Plugins/IOS/libOneSignal.a(OneSignal.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture arm64

clang: error: linker command failed with exit code 1 (use -v to see invocation)
"
OneSignal.o is a script from the asset store. So I don't really know what's going on there. But it never caused any problems with 5.2.2.

Any ideas?
Greetings,
Shu

EDIT:
Alright, I fixed the bitcode issue:
Project -> Build settings -> All -> Build options -> Enable Bitcode -> No
Is this bad? I don't know if bitcode should be enabled and this is just a bad workaround.

Also, now that it's running:
There are still major performance hiccups just like the ones introduced with 5.3.

EDIT2:
I just wanted to compare the profiler to 5.2.2, but if I try to run the game in the editor, the editor will crash. Tested that multiple times. There are no errors or anything. Just a plain crash.
Just some more information on this: I cloned a project completely for testing with 5.4 beta. And this exact project is running 100% fine in Unity 5.2.2.

Those problems show up using Unity 5.4.0B10 and Xcode 7.1.1.

 

I think Bitcode is enabled by default on the new versions of Unity, there is a check box in xcode to disable it.
I assume your app dont use it.. so its safe

 

Thanks for your reply! Unfortunately, it's still unusable, though, because of editor crashes and still even worse performance on iPhone 5S than I get on iPhone 4S when using 5.2.2. (low framerate like on 4S, but additionally every few seconds there is lag)
I didn't test the 5.4 build on 4S, but I assume it's going to be about 10 FPS.

 

Ah okay, have you test the latest 5.3.4 to compare, its not surprise we all have to install a few versions of Unity to get things working correctly :-(

 

I'm not sure, but I guess 5.3.3 was the latest version that I tested and the performance problems were still the same. So I doubt 5.3.4 will have changed something. Actually, I'd need 5.3.x for IAPs and 5.4.x because of IAP testing. Would have been glad to use Unity IAP, but I guess there's no way of doing so. I just have to stick with 5.2.2. But I will try 5.3.4 anyway, just to make sure those problems here are 5.4-related.

EDIT:
Alright, I just tested 5.3.4 and those are the results:

same as in 5.4:
- build size twice as big as 5.2.2, too
- bitcode issue present, too

better than in 5.4:
- did not take as long to build as 5.4
- performance slightly better than 5.4, not as many hiccups, but still unusable (on 5.2.2 no hiccups at all)
- editor will not crash when running the game

worse than in 5.4: (actually, this is the same in 5.4) - EventTrigger PointerDown/PointerUp not working properly (PointerUp seems to call PointerDown as well)

EDIT2:
I just noticed <OpenGL 4.1> in the editor title, even though there is no OpenGL 4.1 in the Player Settings's "Graphics APIs". Changing the order of the given APIs (Metal, OpenGLES2 and OpenGLES3 (when activated manually)) will not result in different performance.

EDIT3:
Alright, awesome news:
In 5.4B10, the hiccups are gone when I close Xcode and relaunch the app without it being linked to Xcode. Concerning overall performance, I will have to take a further look with an in-game FPS counter or test on 4S.
It still says "<OpenGL 4.1>", however.

EDIT4:
There is another problem now: The Unity splash screen is gone. In 5.4B10, a white splash screen (different for builds with beta versions?) will show for a very short time just before the game starts. Now, the old issue that I faced back a few months ago, reappears: The splash screen is gone, even in 5.2.2.

Thread for this issue is here:
http://forum.unity3d.com/threads/i-broke-the-unity-splashscreen-sorry.353374/#post-2343703

EDIT5:
Another issue:
Not only will the editor crash when I try to start the game there, but also when navigating in the scene view.
I'm deinstalling 5.4B10 now, though. It's just not working.
Maybe 5.3.4 builds will work without being linked to Xcode. But that's a different topic.

 

Alright, I reported all of them.
If somebody figures out the problem with OpenGL ES 2.0 on iPhone 4S, feedback would be nice.

 

Could you list the bug numbers here so we can inspect specifically?

 

@Alex Lian
Here you go:
(Case 781621) iOS build size doubled*
(Case 781624) iOS Bitcode enabled = Yes?
(Case 781627) iOS - App not running on iPhone 4S
(Case 781630) Unity 5.4.0B10 Editor crashes

*(includes the problem with slow builds)
However, I didn't report the missing splash screen (again), because it's pretty much the same issue I have reported a few months back. So if the report is still there, you can flag it as unsolved? Case number for that issue is here:
(Case 725746) I broke the Unity splashscreen (iOS

 

These two were discussed on http://forum.unity3d.com/threads/unity-5-3-x-build-size-increase-faq.383533
. Basically Bitcode will be added and submitted alongside with your app. Though it will be stripped by Apple servers when end users will be downloading your app from App Store.

I passed 781627 and 725746 to our QA, though they might need your project to reproduce 781627 issue.

 

@Mantas Puida
Thanks for the link! QA already forwarded this to me as well, but the thing is: Build size doesn’t increase by 130-150MB as mentioned there. It actually increases by almost 500MB on an empty project (694,6MB in Unity 5.2.2 and 1,16GB in Unity 5.3.4).

For 781630, I am downloading B11 right now and I will try again.
For 781627, I update Shader Forge and I will try again, because as it seems to be a graphics problem, this might be connected to Shader Forge being outdated.

EDIT:
Alright, B11 didn't solve 781630, but I tried a different project and it works there. Maybe I can figure out what causes the problem.

EDIT2:
Same with 781627: Different project works fine. Solid 30FPS at 19% CPU usage. Will try to figure out what's the difference.

EDIT3:
While I have no idea whether or not this has something to do with the issue (781627), when building the project that doesn't work on 4S (using 5.3.4 or 5.4.0), the following message will show up:

I always click "Skip bundle".

EDIT4:
Updated Shader Forge now and all of the Shader Forge shaders. However, 781627 and 725746 persist.

EDIT5:
Somewhat solved: 781630's crashes were related to Shader Forge shaders. I updated Shader Forge and the shaders from 1.18 to 1.25 and the editor doesn't crash anymore. However, when navigating in the scene view, there is lag.
Here are screenshots of the profiler that shows the effect of navigating:



EDIT6:
781630 persists. I was just getting lucky with sporadic non-failure. So it's not a Shader Forge issue.

EDIT7:
781627:
Just in case this might be helpful:
This is what Xcode tells me after trying to run the build on iPhone 4S:

When the last line shows up, it takes about 30 seconds until Xcode tells me the application quit due to memory pressure.

 

@Shushustorm
I always click "Skip bundle".

Why don't you load the bundle?
I always click load bundle.

 

@Lars Steenhoff
I am just not going to risk corrupting my Xcode.

 

I do the same, never had issues, but to be honest I dont know what it means, always thought it was something needed related to Unity

 

Most like it's a plugin needed to control XCode from Unity, no reason to not load it.

 

I posted my analysis of Unity iOS distribution and installation sizes: I did analysis of recent iOS empty app installation and distribution sizes, might be useful: http://forum.unity3d.com/threads/unity-5-3-x-build-size-increase-faq.383533/#post-2568795
and yes, you should be loading Xcode plugin, as otherwise Build & Run won't work. This pop-up usually reappears when you switch between Unity versions, because Unity will reinstall different version of plugin.

 

@Mantas Puida
Alright, I really don't know why my build sizes will increase like that then.
For now, I will have to stick with 5.2.2 anyway, due to some other problems like (still happening in 5.4.0B11):
http://forum.unity3d.com/threads/fantastic-shadows-not-so-fantastic-unity-5-4-0b11.377685/

 

Whats the latest with your issues out of curiosity?

 

@MrEsquire
I don't use anything newer than 5.2.2 anymore since I just can't keep going with any version above that, but here are the latest results that I had:

(Case 781621) iOS build size doubled*
unresolved

(Case 781630) Unity 5.4.0B10 Editor crashes*
unresolved

(Case 782331) Bad shadow quality (low texture resolution*
unresolved

Performance hiccups*
unresolved, but only appearing when linked to Xcode

(Case 781624) iOS Bitcode enabled = Yes?*
solved (I should probably have updated an addon, but for a short-term solution setting "Bitcode" to "No" worked just fine)

(Case 781627) iOS - App not running on iPhone 4S**
solved

(Case 725746) I broke the Unity splashscreen (iOS**
solved

*not appearing in 5.2.2
**not specifically 5.4.x or 5.3.x problems. Eventually, I had similar problems in 5.2.2.
So basically, everything works in 5.2.2 now, but not in newer versions.

 

@Alexey
I'm sorry, I cannot provide you with a stripped down project. This just takes too much time.
But I don't think the problem comes from a simulation like that, because sometimes the resolution would turn high again for whatever reason (rarely and as far as I see completely sporadic) and the shadows of a 5.2.2 build are even magnitudes better on actual devices than the shadows I got in 5.3.x or 5.4.x in the editor.
