How to use scroll view for a picture in swift

I dont have the exact image size yet but its going to be 3 times longer than width so lets just say for a example 1500 X 500. I dont want the whole image displayed without the ability to scroll because the image will contain text. So I want the scroll view at 750 X 500. With the ability to scroll down the last 750. Thanks

Hi

Did you look at our tutorial on that subject? https://www.raywenderlich.com/122139/uiscrollview-tutorial

Yeah I saw it and downloaded it but that program is way more complex then what I am trying to do. I would like to have a fixed width that cant be zoomed in on by using fingers. I would just like to use the fingers to scroll up and down in the document and not side to side.
