    We are trying to update our project to .net 4x runtime, API level .net 4x and IL2CPP backend compilation. When running our project in debug mode on a device, we are hitting an exception we haven't seen in any other configuration.
    We are seeing the same error using 2018.2.11f1 and the most recent beta 2018.3.0b4.

    Any help would be really appreciated on this.

    Are you able to submit a bug report about this along with project to reproduce this?

    This appears to be IL2CPP specific so we will need the IL2CPP folks at Unity to take a look at this.

    I just testing an empty project with only one text mesh pro text object added to the scene. Using IL2CPP and .net 4 runtime and api compatibility, there is a runtime error thrown using the most current beta 2018.3.05b. It's not the same runtime error though we're seeing in our own project.

    As per my previous post, can you submit a bug report on this so we can have the IL2CPP team (scripting team) take a look.

    The exact same issue is happening to us.

    It happens only on Debug builds.
    Testing on:
    • Xcode v10.0.0 (10A255)
    • MacOS High Sierra v10.13.6.
    • Unity v2018.2.12f1
    • iPad Mini 2, iOS v11.4.1 (15G77)

    I checked internally and this should be fixed in the latest 2018.3 release.

    Please verify on your end and let me know if you still have this issue.

    I have been battling with this issue also, I just updated my project to 2018.3.0b11 and can confirm that the bug is still present. I am able to reproduce this issue whenever running the project as a Debug build.

    Any update on this? I've updated both bugs I entered with the latest exception thrown in xcode. Still can't get past this issue and debug our ios release.
