I'm testing crash reporting in a SwiftUI app using PLCrashReporter. After a crash, I export the .crash report and symbolicate it manually with:

export DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer

/Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/symbolicatecrash intelcr.crash ExampleCrashReport.app.dSYM

• I'm 100% sure the UUID of the dSYM matches the crash report;

intelcr.crash File; (BEFORE SYMBOLICATE)

• I have tested with both Debug and Release builds (archived and installed on a real device).

• I added @inline(never) to the crashing function.

Despite all that, the output still shows something like this: (AFTER SYMBOLICATE)

The output it should show should actually be the line when the Crash - 2 button is clicked in the ContentView class;

import SwiftUI

struct ContentView: View {
    @State private var exportedCrashURL: URL?
        @State private var isSharePresented = false

        var body: some View {
            VStack(spacing: 20) {
                Image(systemName: "globe")
                    .imageScale(.large)
                    .foregroundColor(.accentColor)

                Text("ExampleCrashApp")

                Button("Crash") {
                    test().getStartedButtonClicked()
                }
                .padding()
                .background(Color.purple)
                .foregroundColor(.white)
                .cornerRadius(8)
                
                
                Button("Crash - 2") {
                    let optional: String? = nil
                    print(optional!)
                }
                .padding()
                .background(Color.purple)
                .foregroundColor(.white)
                .cornerRadius(8)

                Button("Share CrashReport With PLCrashReporter") {
                    CrashTracker.shared.exportCrashReportToDisk { url in
                        if let url = url {
                            CrashShareManager.shareCrashFile(at: url)
                        } else {
                            print("Crash report not found.")
                        }
                    }
                }
                .padding()
                .background(Color.blue)
                .foregroundColor(.white)
                .cornerRadius(8)
            }
        }
   }


struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
class test {
    @inline(never)
    @objc func getStartedButtonClicked() {
        let numbers = [0]
        let _ = numbers[1]
    }
}

I have an older and bigger project in Xcode. Again, I create crash reports using the PLCrashReporter library and there is no problem with the symbolicate operations in that app.

However, when I create a new demo app with almost the same settings, I cannot observe the method names and line numbers in the symbolicate output.

Deployment Settings; (This is the same app settings that gives proper crash output, if there was a problem with these settings, I think there would be a problem with my other app.)

When I try the following command after asking the question, I get the correct output, but I still need it to automatically symbolize directly with the symbolicate command instead of specifying the address manually like this;

atos -o ExampleCrashReport.app.dSYM/Contents/Resources/DWARF/ExampleCrashReport -l 0x104d2c000 0x0000000104d36b48

Output;

closure #2 in closure #1 in ContentView.body.getter (in ExampleCrashReport) (ContentView.swift:45)

Any tips or missing steps?
