How to install swiftly on macOS (until its macOS support is released)

Notice

When swiftly’s macOS support is officially released, please follow https://swiftlang.github.io/swiftly instead of this page.

Prerequisites

• Swift 6 (by installing Xcode 16 or manually installing the toolchain from https://swift.org))
  • Swift 5.x might be ok, but I haven't tested it.
• macOS 15
  • macOS 14 and older might be ok, but I haven't tested them.

1. Build and install swiftly itself

git clone https://github.com/swiftlang/swiftly
cd swiftly
swift build -c release

mkdir -p "$HOME/Library/Application Support/swiftly/bin"
cp .build/release/swiftly "$HOME/Library/Application Support/swiftly/bin/"

2. Create config.json

Create ~/Library/Application Support/swiftly/config.json. (See above for its content)

3. Create env.fish

If you're using fish, create ~/Library/Application Support/swiftly/env.fish. (See above for its content)

If you're not using the other shells (e.g. ash, bash, zsh), create ~/Library/Application Support/swiftly/env.sh. (See above for its content)

4. Configure your shell

If you're using fish, create ~/.config/fish/conf.d/swiftly.fish with the following content:

source "$HOME/Library/Application Support/swiftly/env.fish"

If you're not using fish, add the following line to your ~/.profile, ~/.bash_profile:

source "$HOME/Library/Application Support/swiftly/env.fish"

5. Restart your shell

That's it!
