Convert NSRange in Objective-C to Swift

Question

How do I convert this to Swift:

NSString *searchString = [NSString stringWithFormat:@"%@", @"Apple_HFS "];
NSRange range = [tempString rangeOfString:searchString];
NSUInteger *idx = range.location + range.length;

Thanks

If you use String, you can just reference endIndex:

let searchString: String = "Apple_HFS "
if let range: Range<String.Index> = tempString.rangeOfString(searchString) {
    let index = range.endIndex
    let stringAfter = tempString.substringFromIndex(index)
    // do something with `stringAfter`
} else {
    // not found
}

I included the types so you could see what's going on, but generally I'd just write:

let searchString = "Apple_HFS "
if let range = tempString.rangeOfString(searchString) {
    let stringAfter = tempString.substringFromIndex(range.endIndex)
    // do something with `stringAfter`
} else {
    // not found
}
