SOLVED: How do I know that throws an Error in SwiftUI

Forums > Swift

Below code catches an Error object "error" when the server is not available:

        let (data, urlResponse) = try await request)
    } catch {

When I read up on the documentation of it is nowhere mentioned that it also throws an error (for URLSession.shared.dataTask for example it states explicitly that an error item is part of the returned values).

I mean the code is working but how would I KNOW that it returns an error object? That part is absolutely not transparent to me.


The method signature for looks like this:

func data(
    for request: URLRequest,
    delegate: URLSessionTaskDelegate? = nil) async throws -> (Data, URLResponse

See that throws in there? That's what tells you the method throws errors.


Thank you sir, makes sense! :)
