Xcode 6.3 for iOS 8 apps on El Capitan: possible?

Yes this is possible!

Not with 10.11 B2. IT claims to support only XCode 7.

Since 10.11 Beta #2 all Xcode 6.x versions will have the "no go" sign on their icon and won't launch, stating incorrect OS version.

However ... this can be easily bypassed by locating the Xcode.app in Finder under Applications. Right click and Show Package Contents. Browse into Contents/MacOS folder. Double click the Xcode executable file to launch Xcode (it will bring up a Terminal window - don't close this window as it is the Xcode process).

So yes, it does work, but only if worked around OS X's version compatibility check.

Not a big deal really. There's far worse issues in beta #1 so do upgrade. 😉

Even if it "works" using the above mentioned hacks, it leaves your system in an unsupported configuration. Personally there's no way in **** I would ever put my development platform in that kind of state. It's my bread and butter.

My suggestion is if you want to kick the tires on El Capitan, do it on a different machine, or on a completely separate boot drive. You do *not* want to mess up your production environment.

Yep, I wasn't planning on it. I thought, for a brief moment, the teams had done some really fine work and were supporting the versions across the OS barrier. Having all three pieces move in lockstep is a real buzzkill.

XCode 8.4 seems back to working normally on 10.11 B4
