Error installing Swift Open Source Xcode Toolchain: you cannot install Swift Open Source Xcode Toolchain in this place

Question

I just downloaded the Swift Open Source Xcode Toolchain as described here .

However, following the installation instructions, the second command no longer works, which says:

Run the package installer, which installs the Xcode toolkit /Library/Developer/Toolchains/.

The Xcode ( .xctoolchain) toolchain includes a copy of the compiler, lldb, and other related tools necessary to ensure a seamless development experience in a particular version of Swift.

When starting the package installer, the following error appears:

You cannot install the Swift Open Source Xcode Toolchain in this place. Installer Swift Open Source Xcode Toolchain does not allow which will be installed here.

Update: Someone suggested earlier that the problem may be that I do not control El Capitan (this is true). I was not able to update my OS at the same time, can anyone else confirm with the same question that this could be the reason?

Answer 1

You do not have the requirements described on the Swift download page. The error message you receive is unsuccessful.

Install OS X 10.11 (El Capitan) and it will work.

Answer 2

.. ElCapitan, !
