Answer 1

Why copying to Bundle Dirctory.. There is no way to write in the bundle directory because the bundle dir is code signed with SSL certificate and you can't break it. You can use the documents directory itself for storing files.

Answer 2

The bundle directory(Read here ) on disk is immutable by code, ie a developer cannot change its contents. The documents directory(sandbox) of your application is where you want to keep things.

Answer 3

If you want to add any files to the bundle directory, it must be done at build time using copy resources in the build phases tab. These are usually files that should not be changed for every execution.

If the images you are trying to add to the bundle are for UI. use an asset catalog

For any other type of file (reading or writing) use the documents directory
