Flutter application crashes on iOS 15 #313
Comments

I have the same problem. This is an IOS 15 vs objectbox incompatibility issue. If I change the simulator version to IOS 14.3, everything is fine. |

@ebadta81 you're totally right! I downloaded the iOS 14 simulator and yes, it's working fine. I just changed the title, thanks for that info. |

I can confirm this is reproducible with the example in the repo by wrapping Still trying to figure out an alternative without sacrificing performance. I've also opened an SO question https://stackoverflow.com/questions/69324507/ios-15-sdk-memcpy-not-exported |
|
So far no reaction on SO; maybe also try the Dart bug tracker? Are stdlib functions treated differently (e.g. less calling overhead) than "our" code? If not, we could provide our own C wrapper for memcpy, I guess? |
|
I've also encountered a similar issue in our application, but this only seems to be a problem on iOS Simulators. So far, there have been no issues reported on real devices. |
|
I've created a Flutter GH issue flutter/flutter#90896 |
Yes, that's an option I've had in mind as a "last resort" (because it requires more symbols just for dart/flutter). There should be no performance degradation. |
|
It seems to be a confirmed issue with Flutter itself; can someone confirm it's fixed in the Flutter beta channel? See flutter/flutter#90896 (comment) |

Issue doesn't seem to be fixed yet on Flutter beta channel 2.6.0 Stack Trace: |

I have the same problem when making a query with conditions. The information I have is summarized in the following paragraphs. |
|
Update: not fixed by latest Flutter versions flutter/flutter#90896 (comment) |
On iOS use Dart API instead of memcpy
|
We have released the preview version |
|
Updating to the preview version fixed it for me. |
|
it also works for me with the new version |

1.2.1-dev.0 on IOS 15 box.getAll() FIXED. Nice... |
|
It still doesn't work on each machine with XCode 13.1. Also this 1.2.1-dev.0 version contains Android bug: |
|
@slavamarchenko A little more information would be nice; e.g. to reproduce and ensure it's not a local configuration issue on your side. |
For the Android issue I am using 1.2.1-dev.0 (Flutter 2.5.3, XCode 13.1) release and running: return boxStorage.store.runInTransaction<void>(TxMode.write, () {
// remove all properties with such key
box.removeMany(_findPropertiesByKey(key).map((e) => e.id).toList());
// add new property
box.put(ObjBoxProperty.fromValue(key, value));
});and that I have as error: On 1.2.0 it works perfect. Sorry, I have no possibility to get details for IOS Simulator issue, that happened not on my machine actually. |
|
I get the same error: After upgrading to version 3.0.1 (3.0.0 same error) As i can see, issue has happened because function v2.9.2-RC3 - version ok. Why flutter package needs to link with android aar package and not with native shared library directly? |
|
@slavamarchenko @clouddevil Thanks for reporting. This should be fixed in the latest preview release |
Yes, have not tried on IOS but on Android works fine. Thanks) |

After upgrading XCode to the very recent version 13.0, our flutter app crashes when doing a box.get(id) with an exception : ArgumentError (Invalid argument(s): Failed to lookup symbol (dlsym(RTLD_DEFAULT, memcpy): symbol not found))
