\usage{
swift_function(
  code,
  env = globalenv(),
  imports = c("Foundation"),
  cache_dir = tempdir()
)
}
\arguments{
\item{code}{Source code for the Swift function definition.}

\item{env}{Environment where the R functions and modules should be made available.}

\item{imports}{Character vector of Swift frameworks to import.}

\item{cache_dir}{Directory to use for caching shared libraries. The default
value of \code{\link[=tempdir]{tempdir()}} results in the cache being valid only for the current
R session. Pass an alternate directory to preserve the cache across R sessions.}
}
\description{
Dynamically define an R function with Swift source code. Compiles and links
a shard library with bindings to the Swift function then defines an R function
that uses \code{.Call} to invoke the library.
}
\note{
Remember that the function need to be \code{public} and that you need to put
the required \verb{@_cdecl ("…")} decorator before the function definition.
