A simple plugin framework for Swift applications.
Load dynamic libraries and call their functions dynamically.
Plugin.swift
@_cdecl("loadPlugin")
public func loadPlugin(_ data: UnsafeMutablePointer) -> Int32 {
print("Plugin was loaded!")
return 0
}
@_cdecl("somePluginFunction")
public func somePluginFunction() {
print("Called some library function")
}Main.swift
let plugin = Plugin(name: "Plugin", location: URL.currentDirectory())
// output: Plugin was loaded!
typealias SomePluginFunction = @convention(c) () -> ()
let pluginFn: PluginFunction<SomePluginFunction> = plugin.loadFunction(name: "somePluginFunction")!
pluginFn.function()
// output: Called some library functionWe can compile the above Plugin.swift file with Swift Package Manager by defining a library product for the Plugin target:
.library(
name: "Plugin",
type: .dynamic,
targets: ["Plugin"]
)More examples, see EXAMPLES.md.
The library also supports some basic logging using swift-log.
