Split Fullname in Firstname and Lastname

How can I split a full name in First Name and Last Name.

NSString *fullName = @"John Luke Morite";
NSString *firstName = [[fullName componentsSeparatedByString:@" "] objectAtIndex:0]; //John
NSString *lastName = ?? // Luke Morite

All of the codes in the other answers will crash in different situations. My approach is Messy but works without crashes (Objective-C):

NSString *fullName = @"Mehdi Mousavi Bakhtiari";
NSString *firstName = @"";
NSString *lastName = @"";
if (fullName != nil && fullName.length > 0) {
   NSArray<NSString *> *parts = [fullName componentsSeparatedByString:@" "];
   if (parts != nil && parts.count > 0) {
         firstName = [parts objectAtIndex:0];
         if (parts.count > 1)
            for (int i = 1; i < parts.count; i++) {
               lastName = [NSString stringWithFormat:@"%@ %@", lastName, (NSString *)[parts objectAtIndex:i]];
            }
   }
}
if (lastName != nil && lastName.length > 0)
   lastName = [lastName stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];

NSLog(@"first name: %@", firstName);
NSLog(@"middle name and last name: %@", lastName);

You can also use split to acheive this:

   let text = "Stack Overflow Z"
   var fullNameArr = text.split(separator: " ", maxSplits: 1, omittingEmptySubsequences: true)
   let firstName: String = String(fullNameArr.first ?? "")
   let lastName: String =  fullNameArr.count > 0 ? String(fullNameArr[1]) : ""

A better way:

NSString *fullName = @"John Luke Morite";
NSRange range = [fullName rangeOfString:@" "];
NSString *fname = [fullName substringToIndex:range.location];
NSString *lname = [fullName substringFromIndex:range.location+1];

Here the strategy is looking for the first space, and taking remaining characters

NSString *fullName = @"John Luke Morite";
NSRange range = [fullName rangeOfString:@" "];
NSString *lastName = [fullName substringFromIndex:range.length+1];

NSString *fullName = @"John Luke Morite";
NSString *firstName = [[string componentsSeparatedByString:@" "] objectAtIndex:0]; //John
NSString *lastName = [fullName substringFromIndex:[fullName rangeOfString:firstName].length + 1];
