Is there anything like sandboxing an iPhone Application, what are the benefits on using sandboxes and do they allow me sharing data between one app and another?
I found this link while searching but not able to understand as I'm new to iOS development.

An object that helps a user share data from one place to another within your app, and from your app to other apps. For sharing data with any other app, use the systemwide general pasteboard; for sharing data with another app from your team — that has the same team ID as the app to share from — use named pasteboards.
Sandboxing is designed to prevent apps from gathering or modifying information stored by other apps. Each app has a unique home directory for its files, which is randomly assigned when the app is installed.
The aim of application sandboxing Application sandboxing seeks to improve security by isolating and shielding the application from outside intruders or malware. It's also used when preventing system resources or other applications from interacting with the protected app is necessary.
iPhone apps are all sandboxed, meaning there is no sharing of files between applications. There are some ways of transferring data between applications but they're very limited.
From The iOS Environment
For security reasons, iOS places each app (including its preferences and data) in a sandbox at install time. A sandbox is a set of fine-grained controls that limit the app’s access to files, preferences, network resources, hardware, and so on. As part of the sandboxing process, the system installs each app in its own sandbox directory, which acts as the home for the app and its data.
one solution to transmit data from one to another app is via URL Schemes

Mobile device application developers use the sandboxing capability of iOS to ensure the security of the user data and to ensure that the application don't share data with other applications installed on the same device.
The sandbox forms and maintains a private environment of data and information for each app.
The sandbox can minimize the damage that can be done from a potential hacker but it can't prevent the attack from happening.
Although Apple has built robust sandboxing features into iOS , it is upto the developer's to ensure that their apps are written securely.
When an app is installed on a mobile device, the system creates a unique directory for it.
Sandboxing only prevents the hijacked app from affecting the other apps and also other parts of the system.
