Is Xcode guaranteed to be installed where swiftly is installed? Should we query to ensure that there is a toolchain installed?

If Xcode isn't installed then this will end up prompting the user on the console to install the CLT, and then that could be the system Xcode toolchain that it uses. Otherwise, if the user installs an Xcode, and either sets it with xcode-select or sets the DEVELOPER_DIR then swiftly will start proxying to that.

Add the feature of a special selector "xcode" that can be used like the other swiftly
selectors for some operations, such as
swiftly use, andswiftly list, but has noreal effect on other operations.
With this feature, you can
swiftly use xcodeand then when you run the proxies foritems like swift, clang, and other common toolchain binaries they will be run on the
Xcode toolchain.
When xcode is selected then
swiftly runwill run with the currently selected xcodetoolchain (or command-line tools) reported by
xcrun -fas the toolchain on the path.When you run
swiftly listthere is a special entry for "xcode" that is decorated in asimilar way to indicate whether it is the (global) default, and/or in-use toolchain as a
result of the selection mechanism.
