Hi all. My project works perfectly on all platforms and MacOS Editor, but on iOS device crashes.

I think its something about this bug:

But i’m not sure. Any suggestion will be very helpful.

Unity: 2019.3.1f1

transport: preview.0 - 0.2.3
entities: 0.5.0-preview.17
jobs: 0.2.3-preview.9

I have some updates. Problem was solved by temporary solution.
The reason was in Unity.Transport package. My game starts the udp socket connection with server. There are some Unity.Jobs schedulling in NetworkDriver Class of transport package. I’m sure, that this is bug of preview Unity.Transport Package. I gave some info about this issue into unity issuetracker - Unity Issue Tracker - [iOS] iOS player crashes on UnityFramework`::ExecuteJob() at JobsBindings.cpp:381:13 [opt] when running as a server client
Temporary Solution - use NetworkDriver.ScheduleUpdate() without using Unity.Jobs.
Before:

public JobHandle ScheduleUpdate(JobHandle dep = default(JobHandle))
        {
            long timeNow = Stopwatch.GetTimestamp() / TimeSpan.TicksPerMillisecond - m_updateTimeAdjustment;
            if (m_NetworkParams.config.maxFrameTimeMS > 0 && (timeNow - m_updateTime) > m_NetworkParams.config.maxFrameTimeMS)
            {
                m_updateTimeAdjustment += (timeNow - m_updateTime) - m_NetworkParams.config.maxFrameTimeMS;
                timeNow = m_updateTime + m_NetworkParams.config.maxFrameTimeMS;
            }
            m_updateTime = timeNow;
            var job = new UpdateJob {driver = this};
            JobHandle handle;
            var clearJob = new ClearEventQueue
            {
                dataStream = m_DataStream,
                eventQueue = m_EventQueue,
#if ENABLE_UNITY_COLLECTIONS_CHECKS
                logger = m_Logger,
                stringDB = m_StringDB,
                connectionList = m_ConnectionList,
                internalState = m_InternalState
#endif
            };
            handle = clearJob.Schedule(dep);
            handle = job.Schedule(handle);
            handle = m_NetworkInterface.ScheduleReceive(this, handle);
            var logJob = new LogJob {logger = m_Logger};
            handle = logJob.Schedule(handle);
            return handle;
        }

After:

public JobHandle ScheduleUpdate(JobHandle dep = default(JobHandle))
         {
             long timeNow = Stopwatch.GetTimestamp() / TimeSpan.TicksPerMillisecond - m_updateTimeAdjustment;
             if (m_NetworkParams.config.maxFrameTimeMS > 0 && (timeNow - m_updateTime) > m_NetworkParams.config.maxFrameTimeMS)
             {
                 m_updateTimeAdjustment += (timeNow - m_updateTime) - m_NetworkParams.config.maxFrameTimeMS;
                 timeNow = m_updateTime + m_NetworkParams.config.maxFrameTimeMS;
             }
             m_updateTime = timeNow;
             JobHandle handle = dep;
             m_DataStream.Clear();
             m_EventQueue.Clear();
             InternalUpdate();
             handle = m_NetworkInterface.ScheduleReceive(this, handle);
             /*
             var job = new UpdateJob {driver = this};
             JobHandle handle;
             var clearJob = new ClearEventQueue
             {
                 dataStream = m_DataStream,
                 eventQueue = m_EventQueue,
#if ENABLE_UNITY_COLLECTIONS_CHECKS
                 logger = m_Logger,
                 stringDB = m_StringDB,
                 connectionList = m_ConnectionList,
                 internalState = m_InternalState
#endif
             };
             handle = clearJob.Schedule(dep);
             handle = job.Schedule(handle);
             handle = m_NetworkInterface.ScheduleReceive(this, handle);
             var logJob = new LogJob {logger = m_Logger};
             handle = logJob.Schedule(handle);
             */
             return handle;
         }
