We are storing a xml config file which contains several key-value pairs in UserDefualts. The size of the .plist after the data is stored into the USerDefualts file is in between 5-50MB based on the user config file.
Recently in one of our beta devices, we found that the app Preferences folder is of size 5GB which is 500 times more than the app size.
I downloaded the app .xcappdata for the beta device and found that the folder
AppData/Library/Preferences is 4.98GB
We have no idea why that folder is huge.
Inside that folder there are 800 of files with name in the format
(bundle-identifer).plist.1ESwPpG
1ESwPpG is the random string at the end of files.
And the size of each file shows 0 bytes.
There are two more additional files in this folder.
One is the app .plist (35MB) file and other one is com.apple.EmojiCache.plist (4KB).
Why the folder is over 4.5GB ?
I can delete the app and reinstall it which would solve the problem, it would be useful for us to know the cause of the issue.
I couldn't find much from https://forums.developer.apple.com/thread/69830.
and iOS app's Documents and Data becomes huge
Note: This app on the beta device hasn't been removed from the last 2-3 months. The app in the device is upgraded with every beta build.
Note: Deleting these files does reduce the folder size, but the file is showing 0 bytes when looked at file inspector window. Also the file shows nothing when opened by any text editor.
I see that the userdefault data .plist which is 35MB of size is duplicated many times which increase the folder size.
I'm wondering when exactly this happens.
