Swift Statements

📌 Swift Statements

Swift statements are clean, readable, and strictly structured.

 Types of Swift Statements

    Statements are mainly divided into 4 categories:

1. Declaration Statements

2. Expression Statements

3. Control Flow Statements

4. Jump / Transfer Statements

Let’s understand each one clearly 👇

1️⃣ Declaration Statements

Used to declare variables, constants, functions, and types.

Variable & Constant

Function Declaration

2️⃣ Expression Statements

Any expression that performs an action is a statement.

✔ Function calls
✔ Assignments
✔ Calculations

3️⃣ Control Flow Statements

Used to control the execution flow of the program.

 If Statement

 If–Else Statement

 Else–If Ladder

 Switch Statement

Swift switch is very powerful.

✔ No break required
✔ Must cover all cases

4️⃣ Loop Statements

Used to repeat code.

 For-In Loop

 While Loop

 Repeat–While Loop

Executes at least once.

5️⃣ Jump / Transfer Statements

Used to change execution flow immediately.

 break

 return

 fallthrough (Switch only)

6️⃣ Guard Statement (Very Important 🔥)

Used for early exit and clean code.
