How to remove an app on iOS without overhead? Problem
I tried to remove an app from Settings -&gt; iPhone Storage, but after each installation/un-installation cycle about 100-200mb adds up to disk space (example: after 10 cycles about 2GB might be taken on a disk, even that the app is un-installed).

PoC
Here is a PoC, it's the same without checkra1n and video recording.
Steps to reproduce

Download an app from App Store
Launch the app
Delete the app from Settings -&gt; iPhone Storage
About 100-200mb is taken on a disk on example of TikTok (TikTok binary is ~130mb)
Jump to step 1.

Non-ideal solution
Reboot helps to wipe these taken data from a disk.
Env

iPhone 6s with/without checkra1n on 14.2 and 14.3
iPhone SE without checkra1n on 14.2

What I checked

Snapshots, and there is only system one
Hanged files using lsof, and there is only Asset.car in splashboard for TikTok, but it isn't 130mb file

Question
Why it this happening and how can I delete an app without overhead of 100-200mb + reboot?
Both macOS and iOS use APFS which make snapshots, so I would expect you have to wait for this like installation logs, snapshots and other artifacts to expire based on storage pressure and time.
