Answer / Sandeep Bhatia
In Objective-C, properties can be declared as either atomic or nonatomic. Atomic properties are thread-safe, meaning they provide synchronization to ensure that changes to the property are done atomically, preventing race conditions. Nonatomic properties are not thread-safe and do not perform this synchronization, making them faster but potentially causing issues in multi-threaded environments.
