One of the most frustrating issues that many developers face is the inability of the App Store to perform partial updates for large applications such as Xcode.
This means that every time a new version of Xcode is released, the App Store has to download the entire package again, which can take hours or even days depending on the internet speed and availability. Many users have reported that the App Store often fails to complete the download or installation process, leaving them with a corrupted or unusable version of Xcode.
This is unacceptable for a professional development tool that is essential for creating apps, Apple should improve the App Store's update mechanism to allow for incremental updates that only download and install the necessary changes, rather than forcing users to re-download the whole application every time.
