But some people say first section must be root ,other say swap on disk..
Which one is true?

There is no requirement for any order of your partitions.
Depending on the type of your hard drive, a partition on the logical start of your disk may be "quicker", because the positioning of read head is quicker here. On some other drives this may be true at the logical end of your disk. You have to benchmark your disk to detect the quickest area.
Historically, you have had the opportunity to gain some performance if you optimize your system this way a little bit.
With modern Solid State Drives this makes no sense any more.
One additional note: If you use the modern GPT instead the MSDOS label, you don't have to think about primary and extended partitions.
