I am trying to Start Xcode with the custom toolchain and to be enabled to use the open source version of Swift.
Steps are taken from Swift.org
And I receive this error:
xcrun: error: unable to find utility "launch-with-toolchain", not a developer tool or in PATH
The open source Swift toolchain from https://swift.org/download/#apple-platforms requires the latest Xcode 7.2 (currently: beta 4).
The location of the developer directory used by xcrun and other build tools must be set to this Xcode 7.2. This can be done from the command-line
with
sudo xcode-select -s /path/to/Xcode7.2-beta.app/Contents/Developer
or in the Xcode "Locations" preferences:
