Thanks for reporting this. Could you share a complete stack trace the next time this happens? We won't be able to do anything until we have more steps. |
|
There is actually no crash just randomly seeing it in our logs |
|
Hmm, since that's an exception being thrown, it should crash your app, unless you're catching exceptions, which isn't something I'd advise... Unless I'm missing more context here. I don't think we ever translate this specific exception to an |

I have just experience the same thing after update carthage dependencies. I opens the debugger in the following file "group_shared.hpp" at line 911 in method I am saving an object which i have in a Result where i listen to changesets Here is my cart file when updating carthage dependencies i also get this strange warning |
|
I'm having the same issue when launching my app.
No crash and everything is working fine. It seems to only appear once in the log. |
|
Sounds like I'm not the only one |

Can anyone here actually share steps to reproduce? Seems like this might happen if you're calling |

Not calling realm.refresh() anywhere in our project. Ill set a symbolic break point and see if I can catch it |

|
Managed to get a stack in Simulator (iOS 10.2 / Realm(Swift) 2.1.1 / XCode 8.2). I can't find any pattern that would triggers the exception. |
|
Same here; I've just encountered this as well in tvOS / Xcode 8.2 / Swift (Cocoapods dependency manager). I was Googling for hints and found this issue :) |
|
We'd love to address this, but to make progress we'll likely need a sample project that reproduces this issue. Can anyone who's experienced this provide us with steps to trigger? |
|
I have faced this same problem when i update my carthage file: carthage update --toolchain com.apple.dt.toolchain.Swift_2_3 --no-use-binaries --platform iOS My cart file contains: github "realm/realm-cocoa" I got uncaught exception in "group_shared.hpp" file. I throws this exception : LogicError(LogicError::bad_version) |
|
@kirtiparghi can you share a project that triggers this? What you shared is a way to install Realm, which we're familiar with already, and is not at fault here. |
|
Just a quick ping of this issue. If anyone can provide us with a project that triggers this issue, that would be much appreciated. Thanks a lot! :) Happy holidays! |

Hullo Tim and team, I'm seeing this intermittently with the It seems to happen more often if I take out the NSLog statements... I added the That code is running on thread 1. The exception is occurring in The

I encounter this bug using my app with realm 1.0.2 right after I update Realm up to 2.1.1. It causes db update listener to break. UPD: according to our testers, it breaks even on pure 2.1.1 (without any updating from 1.0.2 to 2.1.1) |
|
I'm having the same issue, realm version: 2.1.1 |
|
First I got a -[__NSArrayM insertObject:atIndex:]: object cannot be nil error then I set an exception breakpoint to try to get this error again but instead I keep getting this N5realm10LogicErrorE: Bad version number exception. Edit: On further investigation, I see that the the array problem is unrelated. |

Ok, I came across this issue as I was trying to figure out why my Realm file was ballooning to over a gigabyte sometimes. Here is where I am at:

This should be fixed by realm/realm-object-store#355. |

Realm v2.4.0 seems to fix that warning for me. |
