Arguments in JSClosure about javascriptkit HOT 4 CLOSED

Thanks. Going through the cases one by one, I noticed that the problem was not with item but a typo in the member name after that (string in this case). By chance, I had picked the only one that actually worked in this case. 🤦‍♂️

What Xcode/Swift version are you using? On Xcode 13.2.1 (swift 5.5), I’m seeing that code build without errors.

I have Xcode 13.2.1 (build version 13C100) and SwiftWasm 5.5.

With this code, I get no errors (just a warning about variables being unused):

import JavaScriptKit

public struct test {
    public init() {
        let closure = JSClosure { (arguments: [JSValue]) in
            guard let item = arguments.first,  let deviceId = item.string else {
                // item in item.string causes error: ambiguous use of 'subscript(dynamicMember:)'
                return .undefined
            }
            return .number(42)
        }
    }
}
