Weird encoding in executable files in ios apps I'm trying to see how does certain ios apps executable files look like, what I do is export the app files to my computer using iexplorer, I then took a look at the info.plist to see the executable files, after that I opened them with my notepad to use the UTF-8 Encoding, but here how does things look like in both files-in the opening of both of the files I see english words that are expressing directories:

Sample of file 1:

Sample of file 2:

Ironically in the second file I can see a huge block of english words absolutely fine, but I dont get it why I don't see the whole file very good? I have also tried to open the files in an objective-c compiler after I have made them .m but that again was useless?
iOS applications consist of compiled code and additional support files, you would need decompilation tools of some kind to get back from the compiled code to readable source. As a starter see

.ipa (file extension)

If you just want to understand how iOS apps are developed you might be better of by looking at sample code within Apple's Developer Documentation and/or some of the various online repositories/courses.
