This lesson is part of Swift · All levels

Summary

This lesson discusses conditional branching using 'if', 'else if', and 'else' in Swift. In Swift, the condition does not require regular parentheses around it, but the curly braces of the opening and closing instruction block are always required to be written. The condition must be a pure boolean expression without implicit conversion of an integer.

Common parentheses around the condition are optional and commonly eliminated
Curly braces '{' and '}' for body code are always mandatory to write
Bool type compulsory condition (number 1 is not considered implied)
