dyci failing on Xcode 7.1

[aure]

I use dyci via KZPlaygrounds for AudioKit's playgrounds (http://audiokit.io/playgrounds/) and recently I've been getting this error on Xcode 7.1. Can someone point me in the right direction to tracking down the problem?

Failed (1) Playground: Recompiled AudioKitPlayground/AudioKitPlayground/Playground.m Executing: /usr/bin/python /Users/aure/.dyci/scripts/dyci-recompile.py /Users/aure/Developer/AudioKit/Playgrounds/AudioKitPlayground/AudioKitPlayground/Playground.m

First of all check if xcode-select is pointing to correct Xcode (in case if you have more than one) https://github.com/DyCI/dyci-main/blob/master/Scripts/dyci-recompile.py#L167-L177 Secondly, make sure that clang-real is really there. clang-real can be removed upon Xcode reinstallation, so you'll need to reinstall dyci again. Hope this helps.

clang-real is not there, and when I reinstall dyci it doesn't error but doesn't create that file.

[PaulTaykalo]

before running install.sh please, make a copy of clang that is about to be replaced:) @aure check the latest version of the dyci install.sh and make sure that you're using this one https://github.com/DyCI/dyci-main/commit/db2b9df366adcc4a6c5e23c6803b3cbc85a2df9b

[aure]

I always use the latest because the install script I use downloads the newest dyci as part of the script:

https://github.com/audiokit/AudioKit/blob/master/Playgrounds/install.sh

I've already run this a few times without making a backup of clang.

[PaulTaykalo]

@aure can you try to install dyci manually and turn on verbose mode in ./install.sh -v?

[aure]

Sure...

still get the same error though. Maybe I need to do this all again on a fresh xcode?

[PaulTaykalo]

Well it's sad, but probably, we just broke Xcode :) Can you compile anything wth Xcode now?

[aure]

Thanks for all your help Paul, after a fresh install of Xcode, everything works perfectly.
