# init(aeDescNoCopy:)

Initializes a newly allocated instance as a descriptor for the specified Carbon AEDesc structure.

## Declaration

```swift
init(aeDescNoCopy aeDesc: UnsafePointer<AEDesc>)
```

## Parameters

- `aeDesc`: A pointer to the AEDesc structure to associate with the descriptor.

## Return Value

Return Value An instance of NSAppleEventDescriptor that is associated with the structure pointed to by aeDesc, or nil if an error occurs.

## Discussion

Discussion The initialized object takes responsibility for calling the AEDisposeDesc function on the AEDesc at object deallocation time. This is the designated initializer for this class.
