# init(objects:forKeys:count:) Initializes a newly allocated dictionary with the specified number of key-value pairs constructed from the provided C arrays of keys and objects. ``` init(objects: UnsafePointer?, forKeys keys: UnsafePointer?, count cnt: Int) ``` ## Parameters `objects` A C array of values for the new dictionary. `keys` A C array of keys for the new dictionary. Each key is copied (using [`copy(with:)`](/documentation/Foundation/NSCopying/copy(with:)); keys must conform to the `NSCopying` protocol), and the copy is added to the new dictionary. `cnt` The number of elements to use from the `keys` and `objects` arrays. `count` must not exceed the number of elements in `objects` or `keys`. ## Discussion This method steps through the `objects` and `keys` arrays, creating entries in the new dictionary as it goes. An `NSInvalidArgumentException` is raised if a key or value object is `nil`. This method is a designated initializer of `NSDictionary`. ## See Also [`- initWithObjectsAndKeys:`](/documentation/Foundation/NSDictionary/initWithObjectsAndKeys:) Initializes a newly allocated dictionary with entries constructed from the specified set of values and keys. [`- init`](/documentation/Foundation/NSDictionary/init()) Initializes a newly allocated dictionary. [`+ dictionaryWithObjects:forKeys:count:`](/documentation/Foundation/NSDictionary/dictionaryWithObjects:forKeys:count:) Creates a dictionary containing a specified number of objects from a C array. --- Copyright © 2026 Apple Inc.
