4.6 iOS 64-bit beta

Thank you. It is compiling in release and even something does run! We have huge project and i think we will catch a lot of errors. Right now it fail somewhere in JSON deserializer with this error:

It seems not all ComponentModel is present, or may be it was stripped, even thou it present in link.xml

 

Hi, I'm unity used in the database is NOSQL database iboxDB, the previous version are all no problem, when I use the latest version of 4.6.1.p3 to compile the 64 bit IOS is wrong.

 

This helps a lot and gives me some direction for troubleshooting. Thanks for the clarification!

 

Sorry for the delay. I tried ljmeier's suggestion but it didn't help. I'll try to get a sample reproducing project done soon. We happened to finish our game so we could release it as 32bit

 

Thanks @joncham we saw this issue in our previous builds !
Keep going guys, you did well !

 

That's awesome!

Sorry I didn't get back to you on this with more details, I haven't had the opportunity to test it more. I've mostly been testing 3rd party libraries I use (when I'm not on non-IL2CPP related tasks of course), so far so good.
I'll make sure to try the next beta releases as they come up. Thanks!

 

I worked around the first Serialization problem so I am not addressing it this time, but I have made a sample app reproducing the second problem. Bug report case is 664604.

 

I just want to know when will you release the p4 IL2CPP unity version ? Or maybe you'll release it in a later patch ?

 

If you have your game ready, then the best solution is to submit now with mono scripting backend and then start upgrading to il2cpp backend.

 

Glad to know 250MB size is not the problem. There is still one more problem that, to run my App, there is specific dependency and procedures you have to follow, this exist in my test environment, but it would be difficult for you to duplicate my environment.

Thanks anyway.

 

Hi, I have another C# PInvoke problem to report.

I have a struct ContentMessage which is one of the PInvoke parameter. There are two data member thumbnailDataPtr and contentDataPtr, if their type is “byte[]”, PInvoke will crash. If their type is “string”, there would be NO crash.

Before IL2CPP, “byte[]” as struct member is OK.

I have been careful, thumbnailDataPtr and contentDataPtr are not null byte array.

############# With IL2CPP, “byte[]” as struct member causes crash#######

[StructLayout (LayoutKind.Sequential)]
public struct ContentMessage
{
public string description;
public string thumbnailUrl;

public byte[] thumbnailDataPtr;

public string contentMimeType;
public byte[] contentDataPtr;
public int contentDataLength;
public string contentActionPrompt;
public bool hasConverter;
}

############# With IL2CPP, “string” as struct member is OK #######

Hi

I am also experiencing this reported bug:
http://fogbugz.unity3d.com/default.asp?662886_oor2q3klpvtjri99

Wasn't sure how/if to vote bugs up . ..
Also any sort of release schedule for making the February 1 DL?

 

Hi, is performance and level loading time something which is planned to be improved in next patch releases? Now I have 1.6 x longer level loading times and 5 to 10 FPS less for IL2CPP build (compared to Mono build, both ARM64 and ARM7 devices)

 

I'm probably just missing something obvious, but is there a reliable way to verify on-device that the running build is in fact 64-bit, and not 32-bit like we've been deploying thus far?

I've been able to build, deploy, and run successfully, but I'd feel much better if I could prove that I'm actually running 64-bit.

 

I had the same thought. If you already have some native code in your project, or are familiar with plugin development, you can just add something like this:

extern "C" int _processorBits()
{
if(sizeof(void*) == 4)
return 32;
if(sizeof(void*) == 8)
return 64;
return 0;
}

I call this function from C#, and display either "32b" or "64b" under my frame rate counter. Shows 32b on my iPad 3rd gen, 64b on iPhone 6, looks good to me

 

I've managed to produce pre-alpha quality runnable build of our project, it still crashes in random places, but many thinks are working already. Main problems that i had to circumvent and/or disable:

1) Prime31 GameCenter plugin didn't link even after update
2) Had to add explicit mentioning of types from ComponentModel in order for JSON deserializer to work (big thank to Unity admin that pointed out the solution). I think IL2CPP should take types from link.xml and add them itself, but right now it does not:

Code (CSharp):

1.     private static System.ComponentModel.Int64Converter _unused = new System.ComponentModel.Int64Converter();
2.     private static System.ComponentModel.DecimalConverter _unused2 = new System.ComponentModel.DecimalConverter();
3.     private static System.ComponentModel.ByteConverter _unused3 = new System.ComponentModel.ByteConverter();
4.     private static System.ComponentModel.CollectionConverter _unused4 = new System.ComponentModel.CollectionConverter();
5.     private static System.ComponentModel.CharConverter _unused5 = new System.ComponentModel.CharConverter();
6.     private static System.ComponentModel.SByteConverter _unused6 = new System.ComponentModel.SByteConverter();
7.     private static System.ComponentModel.Int16Converter _unused7 = new System.ComponentModel.Int16Converter();
8.     private static System.ComponentModel.UInt16Converter _unused8 = new System.ComponentModel.UInt16Converter();
9.     private static System.ComponentModel.Int32Converter _unused9 = new System.ComponentModel.Int32Converter();
10.     private static System.ComponentModel.UInt32Converter _unused10 = new System.ComponentModel.UInt32Converter();
11.     private static System.ComponentModel.Int64Converter _unused11 = new System.ComponentModel.Int64Converter();
12.     private static System.ComponentModel.UInt64Converter _unused12 = new System.ComponentModel.UInt64Converter();
13.     private static System.ComponentModel.DoubleConverter _unused13 = new System.ComponentModel.DoubleConverter();
14.     private static System.ComponentModel.SingleConverter _unused14 = new System.ComponentModel.SingleConverter();
15.     private static System.ComponentModel.BooleanConverter _unused15 = new System.ComponentModel.BooleanConverter();
16.     private static System.ComponentModel.StringConverter _unused16 = new System.ComponentModel.StringConverter();
17.     private static System.ComponentModel.DateTimeConverter _unused17 = new System.ComponentModel.DateTimeConverter();
18.     private static System.ComponentModel.EnumConverter _unused18 = new System.ComponentModel.EnumConverter(typeof(<any your enum>));
19.     private static System.ComponentModel.TimeSpanConverter _unused19 = new System.ComponentModel.TimeSpanConverter();

3) Reflection did't work! Here's relevant stack trace: http://monosnap.com/image/Lp8mOsb8soix0sixF2nRI2W6HKJIBu . I can share relevant code to Unity's admin in pm. But in essence it just looks for fields with certain Attribute in class and change their value.

4) IsDefined on enum always produced ArgumentException:

Code (CSharp):

1. ArgumentException: The value parameter is not the correct type.It must be type String or the same type as the underlying typeof the Enum.
2.   at System.Enum.get_underlying_type (System.Type enumType) [0x00000] in <filename unknown>:0

The code is trivial:

Code (CSharp):

1.   public static bool TryParse<TEnum>(object value, out TEnum val)
2.   {
3.     val = default(TEnum);
4.     Type enumType = typeof(TEnum);
5.     if (!enumType.IsEnum) return false;
6.     string strValue = value.ToString();
7.  
8.         // This line FAILS in IL2CPP
9.     if (!Enum.IsDefined(enumType, value)) return false;
10.  
11.     val = (TEnum)Enum.Parse(enumType, strValue);
12.     return true;
13.   }

It can be that type equivalence is wrong in this case and IL2CPP version can't understande that 'value' is actually is int and can be checked by enum.

 

Engineers can now, iboxDB modify and issued new plug-in, can run well in unity.

 

When I was in unity4.6.1. Used in p3 AudioToolkit v6.5.3 errors:
Serialization the depth limit exceeded the at 'AudioItem. There may be an object composition cycle in one or more of your serialized classes.

Before this version is ok.

 

To save some time, disable the indexing process by going to a terminal and type
defaults write com.apple.dt.XCode IDEIndexDisable 1

On your next build it should only do Indexing Text process. The Index | Processing Files will be skipped.

 

I'm not seeing any difference in loading times between Mono and IL2CPP. Also CPU usage is slightly lower with IL2CPP and FPS higher in CPU-limited scenarios. Are you sure you've set Xcode to build with the Release configuration?

 

My project has errors which might be due the same bug reported by ArjunN. Seems like a problem with serialization. The project is too large to submit for a bug report, but if you need any more details let me know.

Code (CSharp):

1. Exception loading data: System.Runtime.Serialization.SerializationException: Could not find type 'System.Collections.Generic.List`1[[LevelInfo, Assembly-CSharp, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null]]'.

Full device log.

 

Build successful but crashes.
Using Facebook SDK 6.1(https://developers.facebook.com/docs/unity/downloads) which works fine in MonoDevelop 2.x causes EXC_BAD_ACCESS with IL2CPP
It seems to crash after trying to access some FBSettings property which is a scriptable object. The crash seems to be on properties such as frictionlessRequests, e.g.

Code (CSharp):

1. void AssemblyU002DCSharp_FBSettings_CustomAttributesCacheGenerator_frictionlessRequests(CustomAttributesCache* cache)
2. {
3.     cache->attributes = (Il2CppObject**)il2cpp_gc_alloc_fixed(sizeof(mscorlib_System_Object *) * cache->count, 0);
4.     {
5.         UnityEngine_UnityEngine_SerializeField * tmp;
6.         tmp = (UnityEngine_UnityEngine_SerializeField *)il2cpp_codegen_object_new (&UnityEngine_UnityEngine_SerializeField_il2cpp_TypeInfo);
7.         UnityEngine_UnityEngine_SerializeField_m__ctor(tmp);
8.         cache->attributes[0] = (Il2CppObject*)tmp;
9.     }
10. }

 

You could also archive your project in Xcode, then validate it against iTunes Connect. Right now if you validate/upload 32 bit archives, you get a lengthy warning. If your archive has 64 bit it should pass the validation... That would be the ultimate litmus test :-0

 

I'm facing a similar issue to Dimitry when trying to do TripleDES encryption. It throws this error:

I don't see any mention of a fix from unity or a bug report from him. Is this a known issue, or should I submit a new bug?

Note that I tried adding all sorts of namespaces to link.xml, but if Lucas from Unity Tech is right, this file isn't being parsed by IL2CPP so it doesn't solve anything! Right?

 

Thanks for the suggestion @ljmeijer and @JoshPeterson. Unfortunately that didn't seem to make any difference.

Some more info:
Both the classes causing errors are serialized structs. The data is being saved/loaded from byte files. For example, a LevelInfo.bytes file is stored in the Resources folder. The file is assigned in the LevelLoader script inspector as a TextAsset. In LevelLoader.Start, the text asset's bytes are deserialized using BinaryFormatter.

 

@JoshPeterson

I singled out some of the offending code and created an example project. Submitted bug report case 665162

 

Do you know if that's specific to some recent versions of XCode? I'm on 6.0.1, I tried validating a Mono build, and I'm not getting any warning, just "validation successful".

 

If you send the app archive to iTunes Connect it should respond with any errors or warnings. The "is not 64 bit" warning is just a warning at this point.

 

generally in my project I see errors when deserializing stuff. Serializing seems to work however.

This works:

Code (CSharp):

1.     public static string MySerialize(object serializableObject) {
2.         MemoryStream memorystream = new MemoryStream();
3.         BinaryFormatter binaryformatter = new BinaryFormatter();
4.         binaryformatter.Serialize(memorystream, serializableObject);
5.         string tmp = System.Convert.ToBase64String(memorystream.ToArray());
6.         return tmp;
7.     }

This never (?) works:

Code (CSharp):

1. public static T MyDeserialize<T>(string serializedData) {
2.         MemoryStream dataStream = new MemoryStream(System.Convert.FromBase64String(serializedData));
3.        
4.         BinaryFormatter binaryformatter = new BinaryFormatter();
5. #warning THIS FUNCTION CAUSES ERROR ON IL2CPP!
6.         T deserializedObject = (T)binaryformatter.Deserialize(dataStream);
7.         return deserializedObject;
8.     }

I rely on serializing/deserializing like this a lot. I serialize a game engine object to a string so I can save it to PlayerPrefs as a string. Then I read that string back and deserialize it. It worked on mono, granted I used the MONO_REFLECTION_SERIALIZER env variable. http://answers.unity3d.com/questions/30930/why-did-my-binaryserialzer-stop-working.html?sort=oldest This means that yes, this kind of serialising did not work on iOS/mono unless you set that flag to yes. I guess this kind of functionality is not in il2cpp (yet). Does anyone know of a good workaround for this? I'd really like to clear this problem out of the way for now with any workaround, so I can test other parts of my iOS 64 bit app....
