change xcrun developer path
Use xcode-select -switch to choose which version of Xcode you're using by default.
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
sudo xcode-select --switch /Library/Developer/CommandLineTools
In my case, i had to:
- Install Xcode's command line tools, going to preferences -> Locations and setting a correct value to Command Line Tools.
- In Downloads -> Components tab, I clicked install on a line called Command Line tools.
- Marmalade started working fine with Xcode.
