What is memory management in Swift?
Memory management in Swift involves handling the allocation and deallocation of memory for objects to optimize performance.
How does ARC work in Swift?
ARC, or Automatic Reference Counting, automatically tracks and manages the app's memory usage by keeping a count of references to objects.
What are strong and weak references?
Strong references keep an object in memory, while weak references do not, allowing the object to be deallocated when no strong references exist.
Can you explain retain cycles?
Retain cycles occur when two objects hold strong references to each other, preventing them from being deallocated, leading to memory leaks.
What tools can I use to analyze memory usage in Swift?
You can use Xcode's Instruments, particularly the Allocations and Leaks tools, to analyze memory usage and identify issues.
