Do you have any 3rd-party plugins installed? – Haematothermal

No I don't have 3rd-party plugins but after some work I find a solution and now I can run Xcode 7 look at my reply. Thanks – Cobos

Answer 1

After seeing a suggestion here, I solved this issue by deleting Xcode's preferences. The most reliable way to do that is the following terminal command, issued after quitting Xcode:

defaults delete com.apple.dt.Xcode

ETA: Other suggestions have involved changing or removing certain individual preference settings, but after trying a few of those, none worked for me. There seem to be multiple incompatibilities in the preferences between 6 and 7b3, so trashing the prefs entirely should work around them all.

This worked for me. Now I can use Xcode 7 beta 3. Yay! – Buseck

The only solution that works after trying everything! Thank you! – Snowman

Answer 2

Worked for me by doing the following: in the previous version of Xcode(6.4) Preferences > Accounts and delete all the repositories entries. Xcode 7 stopped crashing.

Butts

This is the right answer, apparently the older xcode doesn't mind having invalid repos, but the new one does. – Toggle

Answer 3

For me deleting some plugins off of Alcatraz did the job.

Alcatraz is a plugin manager for Xcode and you can access the list of installed plugins by hitting ⌘ ⇧ 9 and then selecting Installed from the top bar.

Hope this helps someone.

Answer 4

To solve my issue, I have done this:

• I opened Xcode 6.4 (the current Xcode)
• Opened Preferences
• From preferences selected the Location tab
• In derived data I selected "relative" instead of "absolute"
• After this, I can run Xcode 7.
• I restore the same setting as before and all works again

It's very strange, it appears to be a settings error.

Why the down vote? Probably there are different solution but is not correct to vote down. In my case I solved the problem! – Cobos

You are right. But vote is now locked. If you edit that I would clear it. – Snowman

Answer 5

Crash caused by embedding frameworks or linking libraries can be sorted by

app.xcodeproj -> right click -> show package contents -> open project.pbxproj in text editor 

and search and replace the lines containing the newly added framework names.

Then add it again properly once xcode opened successfully.

Answer 6

I had same problem while upgrading from xcode7.2 to 7.3. Everything was fine except the conflicting PLUGINs.

Try removing plugins you might have installed in xcode and it will work. In my case Alcatraz plugin was the culprit. Just removed it from the path /Library/Application Support/Developer/Shared/Xcode and all went good.

P.S : Make sure your mac OS is compatible with the xcode you are installing!! sometimes blindly installing xcode without upgrading OS (like I was doing ;) ) can cause such hazardous behaviour. Best Luck!!

Answer 7

Here is what I did to get it work

first I used the tips of this link combining other answers

so in command line:

sudo rm -rf ~/Library/Developer/Xcode/DerivedData
defaults delete com.apple.dt.Xcode

from the this link to the ruby file

ruby xcode-fix.rb
