问题
Hi I am currently using Xcode 7.3.1 on macOS Sierra. Due to the issue ERROR ITMS 90167. I can't upload my archive using Xcode 7.3.1. So, It's time to upgrade Xcode 8.
But, unfortunately, I can't use Xcode 8 to Develop application due to migration problem on my previous project which was big. All I want is built in Application Loader from Xcode 8. And I need to do some migration on Xcode 8 while I am developing my current app from 7.3.1
And I did download Xcode 8 from Developer Program => Xcode8.xip
Before I install this version, I changed my previous Xcode 7.3.1 to
//Application/Xcode7.3.1.app
inorder to protect overwriting this version.
When I paste Xcode 8(Xcode.app) which i extract from .xip to Application Folder, I open it after its done installing after passing "Installing Component".
Then I open it,it worked (Xcode.app) = Xcode 8.
Then when I open my 7.3.1(Xcode7.3.1.app), it stop working means can't open and show me crash message every time I opened it until I changed my Xcode 8 app title to
//Application/Xcode8.app
So, there will be two Xcode Version on Application Folder. Then when I open Xcode 8(Xcode8.app), it won't let me open and show me error alert again.But, Xcode 7.3.1(Xcode7.3.1.app) come back to live and prompt me to install .git Command Line Tools then I can work back using Xcode 7.3.1.
But then, my problem is I can't open or use Xcode 8 anymore even I change my Xcode app name to different name.Was it "Command Line Tools" causing the problem?
I really need solution to solve this case because I want to use both Xcode Version on my mac.Any Help?
回答1:
Download Xcode DMG files. I have Xcode 7.3.1 in my Applications folder and Xcode 8.0 in my Desktop folder. I use both Xcode very often.
If you already have two Xcode delete one, delete Xcode 8.0. Or delete both of them if you want. And you can download Xcode 8.0 from developer portal or update to macOS Sierra and download the AppStore version of Xcode 8.0. But then you can't download Xcode 7.3.1, you will not get the DMG, I don't think that you can download the DMG from developer portal for Xcode 7.3.1.
So in my opinion the best option is that. delete Xcode 8.0 from your Applications folder. And download Xcode 8.0 DMG from developer portal and put in some other folder not in Applications folder.

I have both the versions of Xcode 7.3 and 8.0. I have installed Xcode 8.0 from dmg file without changing anything in the applications folder for Xcode 7.3.1.
After installation of Xcode 8.0, I observed application folder has only one Xcode version so to open projects in different version I do something like in the image
This works just fine.
