Unity iOS 64 bit support

You should disable stripping level, from a recent discussion I had with Unity technical, IL2CPP does byte stripping automatically and can cause issues if it is also enabled in player settings...

change Stripping Level to disable and might solve your issue

 

I know this is really not a helpful, but I am getting the same thing as sscia and I do have byte stripping turned off. Unfortunately I am unlikely to be able to have the time to create an isolated case for a bug report.

What I can say...
- it's also in Bulk_Generics files
- API Compatibility Level is .Net 2.0, stripping level is disabled

 

Hello, my project builds fine in mono 2.x, but is failing at post processing (unity locks up) when I try building in IL2CPP. Anything generic that could be causing this?

Hold that thought, doing things, installing unity 5.1 aswell to see if thats fixes anything.

It does not seem to have fixed anything, I am noticing a large amount of console window hosts, and unity shader compilers in my task manager processes.

 

Building with IL2CPP takes a lot longer and may give the appearance that Unity has in fact locked up.

 

what I am notic

Oh, I'll let it sit for a bit then I suppose. I've actually gotta go for a little bit, but i'm going to give it another shot when I get back. As I was saying though theres atleast 9 instances of shader compiler running in my processes.

Could it maybe be a shader that is not wanting to compile? a substance perhaps?

EDIT: Odd, but it finished, took like 15 minutes, 32 bit takes a minute or two at most, but I cant complain! Also iOS requires 64bit now I believe as of June 1st.

 

On a side note, is it normal to have 402 caution flags when building? Things like value conversion issue and depreciations... It builds and runs fine, but is that going to look bad to the app store reviewers?

 

Are you seeing those in XCode? I think those are normal. It's not going to affect your final build.

 

So what's the problem with all the value conversion issue warnings? I Never saw those before Unity 5, and still seeing them with 5.1 Is the problem going to be fixed?

 

Sorry, not what I meant. I actually started seeing that warning in 4.5 or 4.6, when I first tried using IL2CPP. I continued to see the error in 5.0 and now 5.1.

 

Well, we had 365 of those benign warning messages (value conversion) using 4.6.5 f1 and our 425mb universal RPG game Omber was approved for sale today in the App Store. The benign error messages did not apparently send up any red flag. I was a lot more worried that the code plugging in a link to my website would cause a problem, but not at all.



Very happy and moving on now to Unity 5, where if I still have these error messages will not worry. Hopefully eventually they will disappear. Thanks for a great engine.

 

Hello,
since when we switched to IL2CPP scripting engine (for 64bit compatibility) we have several users report random freezes. After investigation we found out that the function Resources.UnloadUnusedAssets hangs (seems an infinite loop since it's not a crash) with the following call stack that I got by pausing the app.



Due to a large number of textures used to display the user's avatars we put a call to Resources.UnloadUnusedAssets every time an avatar is not used for more than 10 seconds. For this reason, with a lot of connected users, we could execute this function many times at second, but this never did cause problems in the past. We are going to change our code to call the function less frequently and hope it will not hang.
Is anyone else having a similar problem? Are there specific caveats to using the UnloadUnusedAssets function?

We don't have any problem with the Android and PC versions, we patched Unity to version 4.6.6p2.

 

Hi

We are getting the following crash on iOS arm64 and Universal builds (not armv7). The attached screen shot is from a development build, but the crash occurs on normal builds also.

Can you tell from the screenshot what the issue might be? I have not submitted a formal bug report yet.

 

Hi Josh

Thanks for the response, but I managed to move past this issue by updating the Tapjoy plugin that we're using. For some reason I missed the Tapjoy references in the call stack....it was late!

Regarding marshaling directives...you've lost me, I'm not familiar with the term. But if something looks wrong to you, could you elaborate a bit more please?

 

The Resources.UnloadUnusedAssets look like has been resolved in
Patch 4.6.6p3

(700507) - iOS/IL2CPP: Avoid deadlock during UnloadUnusedAssets.

 

Ah I see. Thanks for the explanation. I've not seen any such attribute usage in our code, but there may be in the Tapjoy code. But like you say, all seems to be working now so I'll leave it alone.

Cheers.

 

We use GetManifestResourceStream in our game for embedded resources. It's been working great on 64 bit devices, but today we've discovered that it's not working on 32 bit devices! There's no exception, but GetManifestResourceStream always returns null. We're using Unity 5.0.3p2 at the moment. I'm going to try updating to 5.1.1 and see if that helps, but wanted to post here about it in the meantime in case this is something still outstanding.

 

Hmm, unfortunately I cannot even build for iOS on 5.1.1. I'm getting an exception:

Code (csharp):

12. UnityEditor.HostView:OnGUI()
13.  

Calling PluginImporter.GetAllImporters() reveals there are two null entries. Not sure how I can find out what they are though. If I call PluginImporter.GetImporters(BuildTarget.iOS) I get that exception immediately.

 

Interestingly, in 5.1.1p1 I get an additional error first:

Code (csharp):

1.  
2. NullReferenceException: Object reference not set to an instance of an object
3. UnityEditor.Modules.DefaultPluginImporterExtension+<GetCompatiblePlugins>c__AnonStorey6F.<>m__F9 (UnityEditor.PluginImporter imp) (at /Users/builduser/buildslave/unity/build/Editor/Mono/Modules/DefaultPluginImporterExtension.cs:133)

11. UnityEditor.HostView:OnGUI()

And then what looks to be the same exception:

Code (csharp):

2. NullReferenceException: Object reference not set to an instance of an object
3. UnityEditor.PluginImporter+<GetImporters>c__AnonStoreyE.<>m__F (UnityEditor.PluginImporter imp) (at /Users/builduser/buildslave/unity/build/artifacts/generated/common/editor/PluginImporterBindings.gen.cs:107)

Thanks Josh! I'll see if I can make a small test case for the embedded resource problem and submit a bug.

Comparing GetAllImporters() between PC platform and iOS platform reveals the problem: the missing one (twice) is /Applications/Unity5.1.1/Unity.app/Contents/UnityExtensions/Unity/Networking/Editor/UnityEditor.Networking.dll

The same thing happens on Android platform too.

I noticed that Unity wants to rebuild the project when updating now. We use Fast Platform Switch because switching platforms manually in our project takes several hours (especially for iOS and Android). I updated the project on the PC platform (since that only takes about 15 minutes), so it looks like something in the "rebuild" is platform specific.

Is there a way to get Unity to do that rebuild operation again?

 

@JoshPeterson

I made a small test project for Unity 5.1.1 and found that GetManifestResourceStream doesn't work on device for either 32 bit or 64 bit now. It works in the editor.

I reported a bug through the bug reporter tool and the number is 707132.

 

Looks like we're going back to 5.0.2p2 for the moment because that's the last version I have that fully works. Let me know if there's any more info/etc I can provide!

 

@JoshPeterson


Xcode 6.3.1 and Unity 4.6.6f2, How can I fix it?

 

Attach playersetting capture.

 

I'm abit confused about 64bit requirements... in Unity docs here... http://docs.unity3d.com/Manual/iphone-64bit.html
il2cpp seems like this mode is required for 64-bit ? but I'm pretty sure I shipped an update to an iOS app, without this switiched on, after the Apple deadline...
So question is... is il2cpp required ? or just a new 64bit feature/option with some more performance benefits ?

 

Since Apple now requires 64-bit builds, why is IL2CPP not the default for iOS? Seems like a bug.

 

Odd. Started the project in a 5.0 patch release. It's been Mono2x. 'Course googling eventually got me what I needed, but just looking at the Editor UI, 'Scripting Backend' is less informative than '32-bit only' vs '32+64-bit' for that drop-down's label.

 

Many thanks

 

Please See the following video to understand errors while building for IOS in IL2CPP.

I did not had this issue with same code base in Unity 4.6.6f2 but have this issue in 4.6.9f1

Please help i am stuck and project has already gone way over timeline.

Please explain me to how to report this bug?

 

hi M40 Dev, have you found a solution, I'm in your same situation.
Thanks in advance.

 

Maybe I am incorrect then, IL2CPP may not have been the default until 5.1, sorry. Note also that IL2CPP does not necessarily imply 64-bit. You can us the Architecture option in the iOS player settings to specify armv7 only, which is 32-bit. But for iOS app submissions, you want the Architecture option to be Universal (which should be the default).

 

My game has a lot of features and bugfixes that were introduced in the last two months but I haven't submitted it yet due to the giant binary size (~100 MB for a Mahjong game).

Does anyone know if it's possible to submit a 64-bit only app to the App Store?
