    Hi,

    our iOS app is crashing at launch when using the built in analytics plugin with Unity 5.1. We switched from 5.0.2 with the manual installed analytics plugin. I changed the code based on the integration tutorial on the analytics site and removed the old analytics plugin.

    If I delete all the analytics code and remove the cloud project id from the player settings everything is working fine. I can reproduce the crash on an empty project.

    We are testing on iOS 8 devices with the latest non beta release of Xcode. There are no problems with builts on any other platform. The app doesn't crash if we switch back from IL2CPP to Mono.

    Edit: Link to our test project. You must add your cloud project id:

    Best

    This is a IL2CPP bug, probably related to stripping. :oops: Which version of 5.1 do you use? Would it be possible for you to report this as a bug with a minimal reproducible and the steps on how to reproduce it? You can also link this thread in the description! Once reported just post the numbers here so we don't miss it! We will have a look and if there is a temp. workaround until the issue is fixed I'll post it here. :)

    Hi @Tuni - our team is aware of the issue and we're working on a fix. We'll try to push out a fix in the next patch update of 5.1 (hopefully next week). If the meantime, we do have a workaround here.

    Thanks for your patience and sorry for the inconvenience!

    I also struggled with this bug for the last two days, so thanks for this hotfix. It indeed resolves the issue for me.

    Hello there
    @Mint Mobile I need a little more info before being able to help you. Does it happen with all projects? Is there a log or error message anywhere? Does it crash with a message or simply shut down?

    Thank you for your time!

    I am having this same Issue with 5.3.2f1 and 5.3.2.p3 with IOS devices running ARM-64. This only occurs on a Second Unity Build of the project using 'BuildOptions.AcceptExternalModificationsToPlayer' or Append of the xcode project.
    This error can be worked arround if you only with arm-7 support. Is there a fix for this or other work around that will allow me to Append to a project and keep ARM-64 for AppStore Submissions?

    @grag0042 Just to be sure, this happens only when analytics is enabled or also without it? Thank you for your time!
