# CFBundleGetMainBundle()

Returns an application’s main bundle.

```
func CFBundleGetMainBundle() -> CFBundle!
```

## Return Value

A CFBundle object representing the application’s main bundle, or `NULL` if it is not possible to create a bundle. Ownership follows the [The Get Rule](https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFMemoryMgmt/Concepts/Ownership.html#//apple_ref/doc/uid/20001148-SW1).

## Discussion

CFBundle creates a main bundle whenever it possibly can, even for unbundled apps. There are a few situations in which it is not possible, so you should check the return value against `NULL`, but this happens only in exceptional circumstances.

For an explanation of the main bundle, see [Locating and Opening Bundles](https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFBundles/AccessingaBundlesContents/AccessingaBundlesContents.html#//apple_ref/doc/uid/10000123i-CH104-SW6) in [Bundle Programming Guide](https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFBundles/Introduction/Introduction.html#//apple_ref/doc/uid/10000123i).
