Build fails after using CocoaPods

Question

I am using CocoaPods for the first time. Installing required libraries causes the build process to break.

Installing Podfile gives this warning:

xcrun: error: active developer path ("/Volumes/Xcode 6.1/Xcode.app/Contents/Developer") does not exist, use `xcode-select --switch path/to/Xcode.app` to specify the Xcode that you wish to use for command line developer tools (or see `man xcode-select`)

The following is the build error message:

clang: error: no such file or directory: '/Users/aztunwin/ObjC/DenkoStation/Pods/Target Support Files/Pods-RKValueTransformers/Pods-RKValueTransformers-dummy.m'
clang: error: no input files
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1

Answer 1

The first error appears to be because you originally launched Xcode 6.1 from your disk image (.dmg) file, so that's where MacOS appears to be looking for the command line tools. You need to reset that.

Go to terminal and type in:

xcode-select --switch /Applications/Xcode.app

Your copy of Xcode is really found in your /Applications folder (as I can see from the second error output). Once you set the command line tools path using xcode-select, clean your project and restart Xcode and try building again.
