Xcode 4+

13GB free, and trying to install a 5.46GB application saying “need 3.6GB” . What the heck?
(Even after i deleted the prior version of Xcode, so it wouldn’t need to move things out of the way / have two coples installed at same time / etc)

Sort out the install requirements please, or at least indicate in the App Store size parameter, that you need X Gb to install.

As a former python coder, Apple's Swift UI is simply incredible, although I see people complain the app "Takes up to much space", quite an irrelevant arguement. The reason for it taking space is evident:
1. Providing Virtual Machines such as IOS uses a considerably larger amount of space.
2. The software isn't "Apple's Pushing Strategy", it contains a high amount of automated command lines you can add, this type of data cannot be compressed or unzipped, as that would cause instablity.
Conversely, it annoys me greatly people impulsevly bomb review this app without any knowledge of why or how the files actually take up such a large amount of storage. Spoiler, IT IS BECAUSE THEY MADE A QUALITY APP!!

36.7 GB storage ..still get the warning 'need more storage space'. How much can you keep moving, clearing or deleting data without knowing how much space you exactly need.

At some point I suppose, many like me would've thought of buying new gadgets from Apple if you want to build and test on iOS and this could potentially be Apple's strategy of pushing people to continuously buy their new products, because of issues self created by them (space and/or performance issue during upgrades) and not solving them. I could be wrong, but as it has been ages and this problem still persists it makes me think that this could be true. Apple please prove me and others wrong and get this fixed for all the developers.
