Opening Xcode 6 Beta
After downloading Xcode following the previous Swift 1 - Download Xcode and start your first iPhone app tutorial, you are ready to open up Xcode.
If it’s slow to open a beta version of Xcode 6, the Mac app Gate Keeper is trying to make sure that the 5GB install is safe to use. It might take 1-2 hours to open Xcode beta the first time.
To speed it up, try this Terminal command. When you make apps or write code, it's good to become comfortable with the command line. You can open Terminal by pressed Command + Space
- Open Terminal (Command line on Mac)
Press Command + Space to open Spotlight (Top right magnifying glass)
- Type Terminal and press return
- Type each line, followed by pressing return (after $ symbol)
cd /Applications xattr -d com.apple.quarantine Xcode6-Beta7.app
Xcode 6 Beta will open much faster, and it won't be checking to make sure the file is safe.
