XCode6 cannot be upgraded to XCode8 anyway. Why ?, Xcode6xcode8

The development payment requires the IOS9.0 version, but the original XCode version is 6.0, so the highest version is 8.3. Therefore, the upgrade is required, but no update prompt is displayed when you open the update center, therefore, download from the AppStore. Because Xcode has been installed on the local machine, clicking download becomes an update. However, clicking update does not respond, but does not respond, later, I thought it was because of the Xcode problem. I wanted to delete it and reinstall it. I found that I was prompted to upgrade the system. So I upgraded the system first. After the system was upgraded, then update the appstore and find that it is OK. You can update it.

Summary:

1. Update the system version first in any case;

2. Update the Xcode version;
