What is the most succinct way to get the first 5 characters of a String in swift? Thank you.
253
string str = yourStringVariable. Substring(0,5);
To get the first N characters of a string, we can also call the substring() method on the string, passing 0 and N as the first and second arguments respectively. For example, str. substring(0, 3) returns a new string containing the first 3 characters of str .
To get the first character from a string, we can use the string. first property in swift.
To remove the first character from a string , we can use the built-in removeFirst() method in Swift.
First 5 chars
let str = "SampleText"
let result = String(str.characters.prefix(5)) // result = "Sampl"
SWIFT 4
let str = "SampleText"
let result = String(str.prefix(5)) // result = "Sampl"
In Swift 4 it changed:
let text = "sampleText"
let resultPrefix = text.prefix(5) //result = "sampl"
let resultSuffix = text.suffix(6) // result = "eText"
