Issue with TensorflowLite Interpreter in IOS release build about flutter-tflite HOT 12 OPEN

@shaheer20 Did you follow this step: https://github.com/tensorflow/flutter-tflite#android--ios

Specifically:

When creating a release archive (IPA), the symbols are stripped by Xcode, so the command flutter build ipa may throw a Failed to lookup symbol ... symbol not found error. To work around this:

In Xcode, go to Target Runner > Build Settings > Strip Style
Change from All Symbols to Non-Global Symbols

I had a similar issue recently and that was the solution.

can you maybe show more code?
it is hard to tell whats wrong from this snippet

from flutter-tflite.

@gregorscholz This where I am getting the issue.

Now i am getting this Error in catch:
'error while loading invalid arguments(s): Failed to lookup symbol 'TfLiteModelCreate': dlsym(RTLD_DEFAULT, TfLiteModelCreate): symbol not found'

from flutter-tflite.

Did you double check if the model is correct? Maybe there is some error with the model?

from flutter-tflite.

It is working fine on Android and IOS (debug) . The issue only occurs in the build i download from test flight for IOS.

Oh sorry, yea, mb.
I think i've read some time back someone had also problems with ios release build while it worked in debug.
I will try to find it

Edit:
Maybe one of those can help

This is showing how can i load the model. I don't have any issue with loading the model it just happens when I pass model to Interpreter. I have tried to get the model into a file and check the size that shows I am getting the right file and there is no issue in getting the file.

This example shows an error while compiling I only get an error when I run the app on an IOS device in release (From test flight).

Was a solution found to this? I’m facing the same issues. Works fine in debug but release doesn’t on TestFlight

from flutter-tflite.

Not yet. Did you try the below solution is any one of this works for you?

@kvanry Thanks it works fine by changing All Symbols to Non-Global Symbols. But It's not working on iPhone 7.

@PaulTR FireStore recommends statically linked libraries, is there a plan to make a more robust fix for this for better integration with other google products?

Hello. I have a similar problem in 2024. Everything works in the debug version, but the release version does't work. Xcode does't add the framework to the ipa file.

I'm using the latest version of tflite_flutter: ^0.10.4
Options:
Strip Style = Non-Global Symbols
Strip Linked Product = No

MacBook Pro Apple M1 Pro Sonoma 14.3 (23D56)
Xcode Version 15.2 (15C500b)

I also tried adding frameworks manually.
They are added to the ipa package, but the package cannot be installed or uploaded to TestFly.

Asset validation failed
Invalid Bundle. The bundle Runner.app/Frameworks/TensorFlowLite.framework does not support the minimum OS Version specified in the Info.plist. (ID: 8c2faa9d-72b6-4024-b1b2-4849a7aa2afe)

What am I doing wrong in my life? :)
Thanks in advance for your help.
