Swift - Collections

Identify the error in this Swift code related to collections as value types:

var list1 = ["a", "b"]
var list2 = list1
list2.append("c")
print(list1)

ANo error; output is ["a", "b"]

BAppending to list2 causes a compile error

Clist1 changes unexpectedly after modifying list2

Dlist1 and list2 share the same reference

Step-by-Step Solution

Solution:

Step 1: Analyze value type behavior in code
list2 is a copy of list1; modifying list2 does not affect list1.
Step 2: Check output of print(list1)
list1 remains ["a", "b"] because collections are value types.
Final Answer:
No error; output is ["a", "b"] -> Option A
Quick Check:
Value types keep original unchanged [OK]

Quick Trick: Modifying copy doesn't affect original collection [OK]
