Provides a way to scan a specific network or the local networks for hosts which satisfy an arbitrary condition.
The API and implementation use Swift Structured Concurrency (await/async, Task, etc).
For example, to find all HTTPS servers on the local network that respond successfully to a request for their main page:
import Foundation
import NetworkScanner
let scanner = NetworkScanner(concurrencyLimit: 250) { address in
guard let URL = URL(string: "https://\(address)") else {
throw Errors.unableToConstructURL(address: address)
}
do {
_ = try await session.data(from: URL)
return .hit
} catch {
return .miss
}
}
for try await result in scanner {
print(result) // e.g. "192.168.0.10: Hit"
}
enum Errors: Error {
case unableToConstructURL(address: String)
}See the documentation for more details, as well as the included demo application for more probe examples.
