Explain the background, my computer is downloaded from the AppStore Xcode7.2, and then downloaded from the Internet Xcode7.3 installation package, and then installed 7.3, the computer has 7.2 version and 7.3 version, but in the installation of 7.3 in the time of the skip Bundle , and then the project has a little problem, here is the solution:
First step: Finder---> Applications---> Right-click 7.3 version of Xcode-----> Show Package Contents.
The second step: "Contents"----> "Info.plist", the key field "Dvtplugincompatibilityuuid" the corresponding content backup, reserved for later use.
Step Three: According to the Xcode plugin path:"~/library/application support/developer/shared/xcode/plug-ins", find the plugin
Fourth Step: Right-----> "Show Package Contents"-----> "Contents"----> "info.plist". Check the "Info.plist" of the two plug-ins, respectively, if the item corresponding to the key field "Dvtplugincompatibilityuuid" contains the contents of the second step above, if it contains, Delete the item that it is on, and then restart the computer, or restart the computer if (both plugins are not included).
Fifth Step: Step fourth to find the Info.plist file for all plugins , add the contents of the second step back to the item (new item) under "Dvtplugincompatibilityuuid" in the key field. Then restart your computer.
Sixth step: Reopen version 7.3 and you will be prompted with "Load bundle" and "Skip Bundle". Select "Load Bundle".
If the above method has not been resolved, it may be that the step you did not notice, it may be other factors, personally think, the problem must be related to this, you can try to solve their own.
