Swiftly is incompatible with Swift shipped in Xcode

[gregcotten]

Swiftly needs functionality to let the user switch between Xcode and the Open-Source Swift toolchains. If a user installs swiftly today on macOS, any use of swift from the command line will only ever use the currently selected Swiftly-selected toolchain.

There should be some kind of way to disable swiftly so I can see my Xcode toolchain. I just want to swiftly disable or swiftly enable if there isn't going to be interoperability with existing toolchains through Xcode (due to portability between platforms ...).

My only workaround is to comment the swiftly ~/.zprofile addition and reload my zsh shell, just like I can comment out my $TOOLCHAINS=... line when doing Embedded Swift.

# Set the toolchain to the latest installed:
# export TOOLCHAINS=$(plutil -extract CFBundleIdentifier raw /Library/Developer/Toolchains/swift-latest.xctoolchain/Info.plist)

If you have an open Terminal window, you'll probably also need to unset TOOLCHAINS:

export TOOLCHAINS=""

swiftly enable / swiftly disable is probably a good feature overall anyway! Kind of like brew link / brew unlink, it gives the user maximum freedom with their PATH, linker search paths, etc.

Probably any attempt of using swiftly when disabled should at least prompt the user about it, if not outright fail on "swiftly use"

I don't know if it's relevant, but it seems like toolchain installed via Swiftly breaks code completion in Xcode (in VSCode it works well though)

I assume #315 fixes this issue?
