+  .Synopsis
+  Installs the Swift toolchain for Windows.
+
+  .Description
+  Downloads the specified release of the Swift toolchain for Windows and
+  installs it silently on the host. The installer places the toolchain under
+  the user profile and updates the user PATH rather than the machine PATH, so
+  the environment is refreshed from both targets before verifying. Compiling
+  with Swift additionally requires the MSVC toolchain and Windows SDK.
+
+  .Parameter Version
+  The version of the Swift toolchain to install.
+
+  .Example
+    # Install 6.3.3
+    Install-Swift -Version 6.3.3
+#>
+function Install-Swift {
+    param(
+        [Parameter(Mandatory)]
+        [string]$version
+    )
+
+    $url = ('https://download.swift.org/swift-{0}-release/windows10/swift-{0}-RELEASE/swift-{0}-RELEASE-windows10.exe' -f $version);
+
+    $options = @(
+        '-q'
+    );
+
+    # Install-FromExe only refreshes the machine PATH before verifying, but the
+    # Swift installer updates the user PATH, so skip the built-in verification.
+    Install-FromExe -Name 'swift' -url $url -Options $options -NoVerify;
+
+    # Refresh the PATH from both the machine and user targets so the newly
+    # installed toolchain is resolvable, then verify.
+    $env:PATH = @(
+        [Environment]::GetEnvironmentVariable('PATH',[EnvironmentVariableTarget]::Machine),
+        [Environment]::GetEnvironmentVariable('PATH',[EnvironmentVariableTarget]::User)
