Memory Safety in Swift Swift monitors risky behaviour that may occur in the code. For example, Swift ensures that variables are introduced before they’re utilized, likewise, memory isn’t accessed once its deallocated, and array indices are checked for out-of-bounds errors. Swift additionally guarantees that multiple access to a similar region of memory doesn’t conflict, Continue Reading »
