Help/Support GDB just kinda retalking everything i learned

[Taylor Meyer 288 iPad (9th gen) 26.2]

so GDB (GNU Debugger) so all i am doing is basically as the title says if im wrong on anything correct me so STEP 1 first download GNU Debugger on the idevice STEP 2 open up the game or app you want to edit on your i device STEP 3 open a terminal window windows or mac or anything else STEP 4 this is the part where im kinda lost on so would you attach gdb to the game then let gdb read the libraries so like for the game i want to edit zombie frontier 3d so like i want to enable the store so i would try to purchase then im guessing a offset might appear so to that offset add a watch point but the problem is when i try to purchase. the game gets stuck in a infinite loading circle when i do an IAP it just gets stuck don't know how to fix that
