Can not start Iphone Simulator

Hello everbody,

I downloaded Xcode 6.3 and Unity 5.0.2 on my macbook. Unfortunately, I keep getting the following error message in XCode, if I try to start the app on the Iphone Simulator.

The build is always succesful, but I can not start the Iphone Simulator.

I have already switched in Unity: player settings --> SDK Version --> Simulator SDK.

Was does this error mean and how can I solve it?

 

Thanks for the answer. How can I solve this problem?

I only created a cube in my test-project. I don't have installed any plug in. What shall I do?

 

I've got the same problem. I am using XCdoe 6.2 however.
When I build my app with Unity 5.0.1 everything works well.
When I build my app with Unity 5.0.2 and try to run the simulator the same happens to me.
I am using some plugins (TK2D, l2Localization, WRP iOS Video Player).

The error message is in my case:
dyld: Symbol not found: __ZN5metal16g_CurrentEncoderE

The backtrace:

* thread #1: tid = 0x2fba65, 0x0409a001, stop reason = EXC_BREAKPOINT (code=EXC_I386_BPT, subcode=0x0)

I have no idea, what's going on and how to solve this. Any hints are very appreciated.
Thank you,
Grit.

 

I get the exact same "dyld: Symbol not found: __ZN5metal16g_CurrentEncoderE" error.

From the name, I thought it might be an issue with Metal, but I get the same issue if I force opengl. It happens with both Mono and IL2CPP builds.

I am not using any plugins.

 

Same problem here.

Also posted in this thread: http://forum.unity3d.com/threads/ios8-xcode6-compatibility.249533/page-4#post-2116828

A quick grep tells me that the new libiPhone-lib.a references __ZN5metal16g_CurrentEncoderE
The old libiPhone-lib.a does not.

 

Thank you Alexey,
it would be nice to let us know as soon the fix is there.
Kind regards,
Grit.

 

I tested it with Unity 5.0.2p2. Unfortunately I got the same problem/error.

 

Same problem with Unity 5.0.2:
dyld: Symbol not found: __ZN5metal16g_CurrentEncoderE

Any ETA for the fix? Or must I go back to the previous engine version?

 

I'm getting this error also. Is this an issue only with the simulator sdk? For example, if while reviewing my app, apple decide to use the sim etc....

 

This issue was fixed in
Patch 5.0.2p4

 

This is working for me now. Thanks!

 

Was this fix ported to 5.1.0f3 ? Because it looks like I'm having same issue.

 

Me too with 5.1.0f3 . Worked on 5.0.1 but now this ....

 

Getting the same issue with 5.1.0f3. The device build works fine on my iPad but when I try to run on simulator I get the error: dyld: Symbol not found: __ZN5metal16g_CurrentEncoderE

 

Same issue on 5.1.0f3 .
dyld: Symbol not found: __ZN5metal16g_CurrentEncoderE

 

Perhaps related... On the iOS simulator with 5.1.0p1 and 5.1.0f3:

dyld: Symbol not found: __ZN6il2cpp5utils35RegisterRuntimeInitializeAndCleanupC1EPFvvES3_i

 

Still same error -
dyld: Symbol not found: __ZN5metal16g_CurrentEncoderE
unity 5.1.0f3, xcode 6.3.2

 

Where do you download 5.1.1?

 

dyld: Symbol not found: _AddFixture

Running latest everything. Unity, please help!

 

Symbol not found: __ZN5metal16g_CurrentEncoderE

 

I changed it back to Unity 5.1.0p1 and it works now but not on the latest Unity

 

I'm getting this error recently with 5.2.2

 

Please submit a bugreport.
Thanks!

 

My error is the same (Unity 5.2.3 , Xcode 7.2):
ZN6il2cpp5utils35RegisterRuntimeInitializeAndCleanupC1EPFvvES3_i

How do I submit a bug report. I tried Issue Tracking, but no add button...

 

You can find it in Unity Editor menu Help -> Report a bug

 

Have submitted a bug. Thanks!

 

@jimrota IIRC, I had managed to get around this bug for the simulator by building with the Mono2x scripting backend instead of IL2CPP since the simulator wasn't enforcing 64 bit builds. Things may have changed, but it might be worth a shot.

 

Please try Unity 5.3.1.
Thanks!

 

Now I'm getting this error in tvOS builds from U5.3.1.

 

Could you please share detailed error message?

 

I use XCode 7.2 and Unity3d 5.3.2p1 and it seems I have the same error. The function FooPluginFunction is defined by me and used in a c# script.

 

dyld: Symbol not found: __vtcOnSessionEnd
Unity 5.3.2p2

 

I had the same error caused by a plugin I created for iOS which failed when I built for tvOS. It works fine when I build for iOS. It turned out I was missing an Inspector setting as shown in the attached screenshot. Once I ticked tvOS in the Inspector (for the plugin) it re-built to tvOS without issue.

 

I had the same issue, build your library to iOS Simulator (during debug).

If you build your plugin library for Simulator in Xcode, it will be imported when you run your Unity App in Simulator. But if you build your library for Device, it won't be imported in Simulator builds. Also don't forget -ObjC linker flag when dealing with Categories.

 

Same problem here using Unity 5.3.2f1 + Xcode 7.3.1

Symbol not found: _ivcp_BeginRecordingSession

 

Unity 5.5.0f3 + Xcode 8.2.1

dyld: Symbol not found: __ZN14Il2CppIMarshal3IIDE

 

do you know what the issue with this was? I am getting this problem currently, trying to deploy to iPad 2 on IOS 9.3 through Xcode similator. Only error i get is the one mentioned by himssen

 

I am having the following error at runtime:

dyld: Symbol not found: _UnityPluginLoad


My build is successful in XCode but app crashes at runtime.

Any thoughts?
