What's the difference between the atomic and nonatomic attributes?

Here is an explanation of the difference between the atomic and nonatomic attributes in Objective-C:

Atomic Attribute

• The atomic attribute is the default behavior for properties in Objective-C.
• When a property is declared as atomic, the compiler generates accessor methods (getter and setter) that are thread-safe.
• This means that if multiple threads access the property simultaneously, the property's value will remain consistent and valid.
• The atomic implementation uses locks or semaphores to ensure thread safety.
• However, atomic properties can have a slight performance impact due to the overhead of acquiring and releasing locks.

Nonatomic Attribute

• The nonatomic attribute is used to explicitly declare that a property is not thread-safe.
• When a property is declared ...
