AES Decryption working in dev but not from TestFlight

[RyanG2016]

I debated whether to post this to Apple first or here. I decided here first in case someone has run into this before.
i am using CryptoSwift to decode an AES encrypted query parameter supplied to my iOS app via QR Code. In development environment (Running on physical device connected to XCode), everything works perfect. I just submitted to TestFlight and when I install from TestFlight, the decoding fails. Now, I am having mucho issues debugging this from TestFlight so I can't confirm where it's failing but it was working when I was just using base64 encoding in the Query parameters so i has to be something with the CryptoSwift not being allowed to run or the like. The app isn't crashing URL launching so I don't think the package is being stripped out or anything. The base64 decoding was just done using Vanilla swift and not the CryptoSwift package.
I have the "App uses non-exempt encryption" set to NO so I don't get prompted to answer the questions as I was previously not using any encryption. I was able to publish to TestFlight with no warnings so I don't know that's the issue.
I'm hoping someone might have a suggestion as to what the issue might be?
Thanks,

I was able to debug this in TestFlight using logging and the issue is not CryptoSwift. The parameter is getting decrypted properly. Still not sure why I'm having issues but it isn't this. Sorry bout that.
