Say I have a string "Chris1", I want to create a substring "Chris".
In Python I would use regular expressions to split a string or to create groups of substrings.
How would I do so in Swift?
Thank you.
You can use regular expressions in Swift, explicitly use NSRegularExpression or some methods takes String.CompareOptions and you can speciy .regularExpression .
But, generally, you need to write more code to manipulate Strings in Swift than in Python.
let str = "Chris1"
var result = str
if let range = str.range(of: "[0-9]+", options: .regularExpression) {
result = String(str[..<range.lowerBound])
}
print(result) //-> ChrisYou can use regular expressions in Swift, explicitly use NSRegularExpression or some methods takes String.CompareOptions and you can speciy .regularExpression .
