    Hi Unity iOS developer,

    4.6.7p3

    Xcode version:
    6.3.2

    iOS version have been tested:

    It looks like this problem occurs in a p/invoke call from managed code to native code. Can you provide the signature of the native method (chartBoostInit) and the signature of the corresponding extern declaration in managed code (including the DLLImport attribute). I would like to see how this is being called.
