    You can try

    let data = "CITY Singapore"
let res = data.components(separatedBy: " ").dropFirst().joined(separator: " ") 
print(res)

    Or

    let res = data[data.range(of: " ")!.upperBound...] // may crash for no " " inside the string

    Or you can go with this too

    let strData = "CITY Singapore"

if let data = strData.components(separatedBy: " ").dropFirst().first {
    // do with data
}
else {
    // fallback
}

    This is a Regular Expression solution, the benefit is to modify the string in place.

    The pattern searches from the beginning of the string to the first space character

    var data = "CITY Singapore"
if let range = data.range(of: "^\S+\s", options: .regularExpression) {
    data.removeSubrange(range)
}

    You can use String’s enumerateSubstrings in range method (Foundation) using byWords option and remove the first enclosing range. You need also to stop enumeration after removing the range at the first occurrence:

    var string = "CITY Singapore"
string.enumerateSubstrings(in: string.startIndex..., options: .byWords) { (_, _, enclosingRange, stop) in
    string.removeSubrange(enclosingRange)
    stop = true
}
string  // "Singapore"
