Xcode7 is a simple method to use plug-ins & how to download Xcode to earlier versions, xcode7 uses plug-ins
Xcode7 has been available for some time since July 9, 2015, when using Xcode7 and Xcode7.1 \ Xcode7.2, you will find that a series of plug-ins such as vv1_enter-Xcode \ KSImageNamed-Xcode \ HOStringSense-for-Xcode cannot be used normally, the following describes how to use the Xcode plug-in this version;
(1) Xcode7:
1. Check the UUID of Xcode and run the following command on the terminal:
Defaults read/Applications/Xcode. app/Contents/Info DVTPlugInCompatibilityUUID
Here you will get a 32-bit UUID and copy it, for example:
2. Find the directory where the Xcode plug-in is located:
~ /Library/Application Support/Developer/Shared/Xcode/Plug-ins
Select the installed plug-in such as KSImageNamed-Xcode, right-click the package content, and find info. plist.
Find the DVTPlugInCompatibilityUUIDs project and add an Item. The Value of the Item is the UUID of Xcode and save it, for example:
After you restart Xcode, the system prompts "Load bundle" and "Skip Bundle". You must select "Load bundle". Otherwise, the plug-in cannot be used;
3. If you click "Skip Bundle" by mistake:
Find the plug-in installation path and continue to open it in info. plist deletes the same UUID number as in the command end. Generally, in the first or last line, delete the row you added and save it, restart Xcode, and add the xcodeUUID again. The plug-in prompt is displayed again after the restart. Select "Load bundle" again, and then click OK;
(2) how to download Xcode of earlier versions:

Https://developer.apple.com/downloads/
After logging on to the console, you can see the Xcode versions;
