As the warning suggested:

Redistributable static libraries should never be built with module debugging enabled. The debug experience will be degraded due to incomplete debug information.

I believe tsia in the warning message might be your developer machine, simply grep, I got:

grep -r 'tsia' ./Pods/
Binary file ./Pods//MNNKitCore/MNNKitCore.framework/MNNKitCore matches
Binary file ./Pods//MNNFaceDetection/MNNFaceDetection.framework/MNNFaceDetection matches

So if possible, please disable debugging of the MNNKitCore and MNNFaceDetection library module, check if -gmodules was disabled.
