Symbol not found: _UnitySendMessage with iOS simulator

Hello,

We recently moved our project from Unity 2017.2.1 to 2018.3, but ever since we upgraded, we're getting crashes every time a native plugin tries to call UnitySendMessage from the iOS simulator, with the following error.

dyld: lazy symbol binding failed: Symbol not found: _UnitySendMessage

Referenced from: <path to app>

Expected in: flat namespace

I know using the simulator isn't recommended, but we do use it sometimes and builds made with the older Unity version work perfectly fine. Anyone know if there were any changes that we might have missed?

Thanks!

 

i'm getting this same error using unity and facebook

 

So do I!
Broke on this line

[FBUnityUtility sendMessageToUnity:FBUnityMessageName_OnInitComplete userData:userData requestId:0];

 

I'm getting the same error when I can FB.init() function from within the unity.

dyld: Symbol not found: _UnitySendMessage

Exact same issue! Up.

 

Same here, it's a complete showstopper because in order to complete our facebook app review, we need to submit a working simulator build.

Has anyone tried upgrading to Facebook SDK 7.15.1 and can confirm if this fixes it?

 

Crap, I just upgraded to Facebook's Unity SDK 7.15.1 and the same thing happens. UNITY PLEASE FIX

 

I already reported this bug to Facebook Team and they told me the bug lies in Unity 2018.3 and this bug still happen in Unity 2019.1b I have tested, anyone report this bug to Unity?

 

I did the workaround facebook team give me by checking symlink libraries Unity but the issues still stay. anyone pls report this bug to Unity as soon as possible

same issue here, needless to say everything works on actual device....
can't pass facebook review, awesome stuff

unity 2018.3.8f1 , facebook sdk: 7.15.1

anyone has any solution how to bypass this, or perhaps any version where it might be working
according to https://issuetracker.unity3d.com/is...simulator-when-trying-to-login-to-facebooksdk 2019.2.0a9 (latest 2019 version) doesn't fix it... even though it is marked as fixed in 2019.2 - anyone can confirm this?

 

Same issue, I do not use FB, but if it happens with Onesignal, although I do not think it has to be done because I deleted it from the project to try and the error still occurs but instead of the plugin it happens to me in the main.

I think it's related to using any type of internet connection.

Unity 2018.3.9f1

 

awesome news, will test it today and report back - THANKS for addressing this for us!

 

I just tested in 2018.3.12f1 and it still appears to be broken. Same issue: dyld: Symbol not found: _UnitySendMessage.
