Twitter iOS app is greater than 2.5M lines of code

Title is misspelled. Should be <i>than</i>, not <i>then</i>.

Thats like 2500 files each with 1000 lines of code. Seems pretty reasonable to me for the twitter app, Android or IOS. Languages like JAVA and Objective C are verbose, unlike say Kotlin and Swift.

Given all the libraries and services that ios provides, how? Did they rewrite all those rather than use what apple provides?

It seems like it shouldn’t be more than 25,000. Why is it 100x more than that?

Must be 500,000 nested IF statements.

it self explanatory from simple ruby on rails into scala behemoth lmao
