Just to clarify:

I guess this ends as an unsolved (undoable?) issue. :(

Thank you for the DevForums tip. I shared the entire script I'm using. All being done via the command line.

@eskimo - Did I not reply correctly?

I opened a TSI which allowed more time and effort into finding the solution and it turned out to be very simple. In my ExportOptions.plist file, I needed: <key>method</key> <string>developer-id</string>

Thanks ssmith_c. I understand .app is a bundle. I thought the .dSYM file was supposed to live in Contents/Resources/DWARF/. I tried to put it in there before notarization but then notarization rejected the app. Ed

Sorry for a missing first statement: let thisLocation = CLLocation(latitude: lat, longitude: long)

Here is the same code in Swift Playground format: //import Cocoa //import Foundation import WeatherKit import CoreLocation var token = [String]() let escapedCity = "41.736,-88.095" token = escapedCity.components(separatedBy: ",") let weatherService = WeatherService() let lat = Double(token[0])! let long = Double(token[1])! let thisLocation = CLLocation(latitude: lat, longitude: long) let now = Calendar.current.date(byAdding: .hour, value: 1, to: Date())! let nextWeek = Calendar.current.date(byAdding: .day, value: 14, to: Date())! do { let (dailyForecast, hourlyForecast, currentWeather, alertWeather) = try await weatherService.weather(for: thisLocation, including: .daily, .hourly(startDate: now, endDate: nextWeek), .current, .alerts) print(String(format: "%.0f", currentWeather.temperature.converted(to: .fahrenheit).value)) print(String(format: "%.0f", hourlyForecast.count)) print(String(format: "%.0f", dailyForecast.count)) print(String(format: "%.0f", alertWeather?.count ?? 0)) } catch { print(String(format:" Weather try/catch1 error: %@", error.localizedDescription)) print(String(format:" Weather full service not available: %.3f,%.3f", lat, long)) } And returns the message: remoteProcessWasInterrupted

Somehow my Outgoing Connection got turned off. Turned it back on and I'm back in business.

Thank you.

Thank you for your response however a couple of followup questions. "Refer to Apple's official documentation on Wallet passes for detailed specifications and examples." Do you have a URL? I couldn't find any with details of acceptable JSON formatting options. "consider reaching out to the Apple Developer Forums" - Isn't this the Developer Forums?
