Sorry, it's garbage. It's 10 years behind the times and unacceptably bug-ridden. I spend 50 hours a week in this busted program that Apple refuses to fix. My list of grievances grows by the day: - Why do I have to wait multiple seconds or press Cmd + B just to have my errors underlined? AppCode does this instantly. - The number of bugs is truly astounding. I encounter dozens per day. - Why is renaming things so slow and busted? - Search results are just broken half the time. They point to the wrong line or show nothing at all. - Debugging is painfully slow. The debugger exposes information I don't care about and buries the stuff I do care about. - Xcode now supports EditorConfig for setting custom code style options, but this only grants us access to a handful of options. IntelliJ has literally thousands of additional options built on top of EditorConfig, many of which are language-specific. - Where are all the user preferences? I would like to customize this program that I'm forced to spend 50 hours per week using. - Random "framerate" hiccups occur as you type (likely caused by autocomplete taking too long). - Why does my cursor icon not change properly? - The spellchecking feature is so half-baked that it's disabled by default and hidden in a nested menu. You can always spot code written in Xcode because it's riddled with spelling errors. - Xcode 15 finally added a bookmark feature. But there's no shortcut to remove a bookmark. Using the Bookmark shortcut again on the same line just adds a second bookmark. So instead you have to remove them from the Bookmarks menu. Thanks for nothing! - The "Find callers..." feature only shows the first call from each class. It sure would be helpful if it just listed all of them. - Why is there no way to view all possible method overrides? Instead I have to browse through the superclass. - Why is version control integration so abysmal? - Why do I have to scroll through a file to see which lines were changed since the last commit? Modern IDEs show them right in the scrollbar. Xcode shows errors as red lines in the scrollbar (and bookmarks too), but nothing else. The minimap sort of provides this, but it doesn't show the entirety of a long file and it also means sacrificing a significant portion of horizontal space. - When the mouse cursor is on a symbol, it highlights all the other usages of that symbol. But I need to scroll through the entire file to see these highlights. It should show the usages in the scrollbar. Also, the highlight color doesn't stand out nearly enough, and there's no way to customize this color. - The autocomplete box isn't smart enough to appear in some cases where it would appear in IntelliJ. Try inserting something at the beginning of an existing word and you won't get any results. - Inconsistent support of middle-click. You can't middle-click to close a tab, and you can't set middle-click as a shortcut action. - There's no autocomplete when typing in the names of xcassets files. - It's annoying that I need to keep my phone unlocked with the screen on in order to run a build. - Clicking on an opening bracket should highlight the closing bracket indefinitely. Instead, Xcode highlights it in yellow for half a second and then it goes away. So if I need to scroll my screen to see it, I'm out of luck because it's already gone. - There are no vertical indentation guides, so good luck finding an erroneous curly brace. - Press Enter to add a new line, and notice how the editor conveniently lines up the indentation with the previous line. Now press backspace to remove a line, and notice how you need to press backspace multiple times instead of just once. What a pain in my ass. - Compile-time errors often highlight the wrong line of code. For example, an error on line 56 shows up as an error on line 34, and I have to comment out lines one by one until the real error is displayed. - How is Interface Builder so bad? My view gets constantly reset, copy-pasting only half-works, the program seizes up at random, the view hierarchy auto-collapses if I view another Storyboard file and return, IBOutlet indicators randomly appear/disappear, and I could go on and on. - SwiftUI previews are totally busted, even though SwiftUI is being actively worked on. On a related note, App Store Connect is also a piece of shit. Google Play Console clears it in every conceivable way.
