In my project I have stored my sqlite(DB file) file in Document directory and also set UIFilesharingMode - NO , but now user can able to acces the file using Xcode->orginizor and also he can able to modify in table and able to change the data in that dable .
My requirement is, how I can hide or restrict user to not access that file.
If any one have any intelligent idea please share me.
Thanks.
You have to use encryption. There's no way to prevent someone accessing Documents folder and there's nowhere for you to store the sqlite file.

I'm asking this question because I did not find any answer, and I'm starting to believe that it's not possible, due to security reasons. But who knows?
In my app, I simply let the user save a PDF file using UIActivityViewController. The user then chooses Save to file, then selects iCloud Drive.
Now, users ask me to be able to select a default location once and for all.
Is it possible? This location would of course be outside the app container, then I suppose iOS won't grant access unless the user selected it itself.
Yes you can. Using UIDocumentPickerViewController you can ask for a directory, and you can save it in your app. This is explained in detail in Providing Access to Directories. iOS 13 and later.
See also What's New in File Management and Quick Look for sample code saving a directory URL and then reusing it to set the base directory for a subsequent call to UIDocumentPickerViewController
I am in a situation where I need to store a document which can be of any type like. pdf, Docx, excel or an image. now I don't have the option to force only one type.
The issue is what to do for an app to work for ios/android as same. should I ask the user to upload the file and store it on the server and ask them to download every time they need it? or upload a copy to server and store it locally where they can access it.
if later is the way to go as a user might need to access the document offline. so what to do for this?
any plugin to use for the same.
Can someone help me find where CoreData is storing the SQL file it creates in iOS applications?
So far I've tried "Show package contents" on the .xcdatamodel file and also the .xcodeproj file...No dice!
Is there an editor for looking at the contents of these SQL files?
Cheers.
-A
The url parameter of [NSPersistentStoreCoordinator addPersistentStoreWithType:configuration:url:options:error] specifies the location of the file. Find this call in your code and see where you've stored it. XCode templates will put it into the top of your application documents directory, but you can put it anywhere you like.
Note that Apple considers the contents of this database to be opaque and non-user-modifiable. Playing with the data in your store is likely to cause issues with Core Data.
It's typically saved into your application's documents directory, with the name of your data model.
So, for example, if my data model is called AppData.xcdatamodeld, it will be AppData.sqlite inside my app's document directory. You shouldn't really need to touch the .sqlite file though.
Hope that helps!

this is a follow on from this question and the link given it seems that when an app is updated all of the files in the documents directory are copied into the updated apps documents directory and also anything in Library/Preferences. Whats the best way to simulate this for testing purposes?
Just copy the files in ApplicationSupport/iPhone Simulator etc? or has anyone developped any funky techniques for testing this.
I have created .sqlite file in my application's documents folder and created some dummy entries in my database table.
Now just change you code build new application without changing any of the certificate and profile information load the new application.
Now check for the old database table records. It will be definitely preserve under your Document directory in .sqlite file.
This is what i followed when i want to check it for same thing.
If anyone know better way then please feel free to suggest new things.

I have an .xml file that is going to be shipped within my app.
This file contains values that are read from it and saved as an array when the app launches.
Each time the app is run, I want to check with the server if there is an internet connection. If so, I want to get the newest version of the .xml file from the server and replace the one that I currently have saved in my app (this way, the next time the user logs in and doesn't have internet access, he/she will be able to use the old (yet most up to date) data).
What is the best way to do this?
Thanks,
The best way to probably do this is to copy the XML file from the app bundle to a location in the app's sandbox, e.g. the Documents folder. Thereafter you can update the XML content as necessary with newer data from the server. The copy is necessary to allow you to write to the file, since you cannot change the content of your app's bundle because it is signed.
Alternatively, if the data is simple enough, you can just save it to user defaults on first launch and change the defaults on subsequent updates
I might skip the XML altogether, unless it contains a baseline of default settings, and just sync user defaults over the Internet. You can't modify files in the bundle, so your only option would be to copy over a "default-settings" XML file to the application's Documents folder to make it editable.
