Grant the location permission to an iOS app. More permissions here: https://gist.github.com/kasnder/3eb32449512a4dba4a92949c8d337a92

grant_ios_location_permission.sh

#!/bin/bash

# Todo: This currently fails to replace an existing entry in the location permission database. Would be better add to the end of the clients.plist file.

# Usage:./grant_ios_location_permission.sh [bundleId]
# Example: ./grant_ios_location_permission.sh com.spotify.client

# Requirements:
# - iOS device with checkra1n jailbreak (tested on 14.8)
# - Installed `sqlite3` on iOS device from Cydia
# - iOS device plugged into computed and forwarded SSH port with `iproxy 2222 44`
# - Installed public ssh key on your device: `ssh-copy-id -p 2222 root@localhost`

if [ -z "$1" ]; then
    echo "Please pass bundleId"
    exit -1
fi

# Get bundleId from argument (e.g. cn.DGNorya.Norya)
bundleId=$1

# Create backup (-n makes sure to not overwrite existing backup)
ssh -T -p 2222 root@localhost "cp -n /private/var/root/Library/Caches/locationd/clients.plist ~/clients.backup.plist"

# Get path to executable from install logs
executable=`ssh -T -p 2222 root@localhost "cat /private/var/installd/Library/Logs/MobileInstallation/mobile_installation.log.* | grep 'Made container live for $bundleId at /private/var/containers/Bundle/Application/' | sort  | tail -n1"`
executable=${executable##*Made container live for $bundleId at }
executable=`ssh -T -p 2222 root@localhost "find $executable/*.app/ -maxdepth 1 -perm -111 -type f -exec readlink -f {} \;"`

# Download binary plist file
scp -P 2222 root@localhost:/private/var/root/Library/Caches/locationd/clients.plist ./clients.old.plist

# Cleanup if exists
rm ./clients.new.xml || true

# Add to downloaded binary plist file
n=0
echo "`plistutil -i ./clients.old.plist -o -`" | while read p ; do
  echo "$p" >> ./clients.new.xml

done

# Convert plist back to binary
plistutil -i ./clients.new.xml -o ./clients.new.plist

echo "Created new clients configuration at ./clients.new.plist"
echo "Now copy this file to your device, as described here: https://kollnig.net/2022/01/app-research-circumventing-permissions/"

# Stop location service
#ssh -T -p 2222 root@localhost "launchctl unload /System/Library/LaunchDaemons/com.apple.locationd.plist"
#sleep 1

# Copy over new plist file
#scp -P 2222 ./clients.new.plist /private/var/root/Library/Caches/locationd/clients.plist

# Start location service
#ssh -T -p 2222 root@localhost "launchctl load /System/Library/LaunchDaemons/com.apple.locationd.plist"

# Cleanup
#rm ./clients.new.plist

Much, much, MUCH experimentation later - I've come with a suitable solution, check it out here
Thanks again!
