Yes, I know.
I learn it my self within just 3 days (1 hour per day only) when govt build a public pool in my city and I also help 100+ kids to learn it.
Here is short tips from my side if you want to learn.
1. Try to stand in water, walk in water in 2 feet dept water, then slowly slowly increase dept and do this for first day. It is important because I saw 6 feet tall boys drowning in 3 feet depth water because they were unable to put there head high.
Next step is grab any ladder and put your head inside water and hold as long as you can.
This first day exercise will improve your confidence and make you safe.
2nd day. Repeat first day exercise and then after 15 min. Grabe ladder, suck as much air as you can, then sleep in water, your face should be in bottom side, you will realize that youre upper body is floating, so next step is kick. Learn how to kick in water to swim. Watch youtube for details.
3rd day... Just repeat previous 2 day exercise. Once you learn how to control breath and how to kick, that will be enough to swim.
So in just 3 days, you can swim, here I am not saying that you will be master in 3 days, but it will be enough to gain confidence and basic swimming. You can Learn more perfect by watching youtube video and regular exercise.
