I have a string that contains a comma. However, I would like to replace the comma by a point. This must be possible unfortunately I can not get it done. I'm not just getting back the .5. The comma is away only everything that stonged for it unfortunately too.
let cijfers = "38,5"
let start = cijfers.startIndex;
let end = cijfers.index(cijfers.startIndex, offsetBy: 3);
let result = cijfers.replacingCharacters(in: start..<end, with: ".")
print(result)

Removing the specific character To remove the specific character from a string, we can use the built-in remove() method in Swift. The remove() method takes the character position as an argument and removed it from the string.
String interpolation is a way to construct a new String value from a mix of constants, variables, literals, and expressions by including their values inside a string literal. You can use string interpolation in both single-line and multiline string literals.
To remove the last character of a string, we can use the built-in removeLast() method in Swift. Note: The removeLast() method modifies the original string.
You use cijfers.replacingOccurrences not on the correct way, for your purpose.
Try this:
let str = "38,5"
let replaced = str.replacingOccurrences(of: ",", with: ".")
print(replaced)
