Xcode 4+

I've been using Xcode for the past several years, I want to leave a comment that this is a great product. Although I am not sayting that the IDE itself and the graphical whatever editing tricks are great. I focus more on the frameworks, libraries, supprt, tools and the integrated package that tranforms a mac to a development machine, and Apple has consistently been great at supporting the development on OS X (macOS). The suggestion might be to provide an integrated end-to-end pakcage that becomes the ultimate development environment so I won't have to install 3rd party packaging systems, library systems, extra-IDEs for different languages, and dozens of emulation, environment, and differnet packages and dependencies for differnet tasks. Putting everything in Xocde seems a bad idea to increase the size (and responsiveness) of the software but it is much better than the overhead of doing fancy stuff and launching dozens of programs just to start working (which takes up lots of concurrency resources which a dual-core laptop I am using might not be the best choice).

There are a few things I don't like about Xcode, but as a whole, it is the best totally free option for iOS development. Better yet, it is totally native. I am an amateur developer, and I have really enjoyed working on Xcode. I recommend giving it a try. The documentation is great and there are a lot of really helpful support videos from non-Apple supported persons, just trying to lend a hand.

I started, knowing nothing about Xcode or Swift, and punched out my first iOS app in less than a month. I was extremely nervous, having all my programmer friends telling me that apple was really strict when reviewing applications. I took the precautions of reading through the Apple documentation before hand, shockingly, my first application went through without a hitch and was on the App Store within 48 hours of submission.

I will admit to using an online class to learn the basics, it was very helpful in getting me familiar with the Xcode environment. I can't provide specifics since I don't know how Apple will feel about promoting someone else's work on a review.

If you have 128GB of internal storage it can be very difficult to manage all of that space. There is no way to only install the features you need, as it comes with absolutely everything except iOS simulator images (those download separately). As a result, you either have to store Xcode on an external storage device or live life on the edge. Otherwise this is a truly delightful and complete IDE. Easily worth 5 stars despite its hardware requirements.

UPDATE:
It's gotten even better since Apple Silicon came out. If you're the impatient type you'll love the new Xcode because everything compiles instantly. It takes milliseconds to compile just about anything. We already know their new desktop processors have groundbreaking performance, but it really shows in Xcode. SwiftUI previews take mere milliseconds to build your whole project and produce a preview. And when you run the simulator it instantly loads your app. It's totally surreal how fast it is to develop software with Xcode.
