document directory vs. bundle resources

document directory: user contents, read/write.
bundle resources: app files, readonly.

Apps on iOS are constrained to a sandbox, they’ve got no access to system files.
Files on iOS have a path, but you usually only work with a URL object that contains that path.

all iOS apps are sandboxed, which means they run in their own container with a hard to guess directory name. As a result, we can’t (and shouldn’t try to) guess the directory where our app is installed, and instead need to rely on Apple’s API for finding our app’s documents directory.
