Help/Support IDA does not properly disassemble iOS binary code, instructions are replaced by empty sub

[YellowGrey 0 iPhone X 14.2]

Hi there,

I had this problem since years and I've never found a solution. I hope someone can help me figure out what's happening and if there is a fix.
I'm disassembling an iOS binary using IDA 7.0 and every time I try to view the code of a method, (IDA View or the pseudocode), all lines of code are sub. If I try to open the sub, it's always empty.
I'm 100% sure that they are not sub. They are instructions like method calling but IDA always shows me this. I've also tried newer versions of IDA but no luck. I tried to ask for help to other people, but they have experienced the same issue.
You can find here an example. Thanks!

That's normal. The subs are probable real functions to which you don't have the name, so it's called subroutine_address.

 

If you double click on them in the pseudocode view you should be able to decompile them as well

Thanks for your answer. Unfortunately, it's not so. They aren't sub but they are real instructions like method calling. I'm sure because in a previous version of the app I could see that, but after a new update, everything is like that code. If I disassemble the code of any method, it's always so.

And those subs are all empty  I don't know what to do
