Swift - Variables and Constants

Consider the following Swift code:

typealias Coordinates = (x: Double, y: Double)

let point: Coordinates = (x: 3.5, y: 7.2)
print(point.x)

What will be the output when this code runs?

A(3.5, 7.2)

B3.5

Cx

D7.2

Step-by-Step Solution

Solution:

Step 1: Understand the type alias and tuple usage
The alias Coordinates represents a tuple with named elements x and y of type Double.
Step 2: Analyze the print statement
Printing point.x accesses the x value of the tuple, which is 3.5.
Final Answer:
3.5 -> Option B
Quick Check:
Access tuple element by name = 3.5 [OK]

Quick Trick: Access tuple elements by their names after aliasing [OK]
