## Overview
The **`startIndex` property** of a string in Swift returns the position of the first character of a given string. This property only works if the string is not empty.
## Syntax
```swift
str.startIndex
```
## Code example


// create strings
let str1 = "Edpresso"
let str2 = "is"
let str3 = "Awesome"

// use the startIndex property
print(str1.startIndex)
print(str2.startIndex)
print(str3.startIndex)

## Code explanation
* **Lines 2–4**: We create the strings `str1`, `str2`, and `str3`.
* **Lines 7–9**: We use the `startIndex` property on the strings we created earlier. Then, we print the results to the console.
