That’s not working on iphone

Your example here trying to use the fixed width font markdown for code will work fine on an iPhone if you use the right character. The apostrophe that you tried to use at the beginning of a line is actually being picked up as the start of a single, curly "smart" quotation ‘ which isn't the right character for code block markdown. You want to use the "backtick" which you can access using the tap-HOLD technique on the apostrophe. Press the key you are using now in the IOS keyboard, but HOLD for a moment until the character selection popup appears. Now, slide over to the one on the far left. This is the backtick :

but a lot of fonts have this character looking very much like the smart single curly quotation mark.
