调用requestLocation()时出现“线程1:信号签名”

import CoreLocation

func checkLocationPermission() {
    if CLLocationManager.authorizationStatus() == .notDetermined {
        locationManager.requestWhenInUseAuthorization()
    } else if CLLocationManager.authorizationStatus() == .denied {
        // 提示用户去设置中开启权限
    } else if CLLocationManager.authorizationStatus() == .authorizedWhenInUse || CLLocationManager.authorizationStatus() == .authorizedAlways {
        locationManager.startUpdatingLocation()
    }
}

import android.Manifest
import android.content.pm.PackageManager
import androidx.core.app.ActivityCompat
import androidx.core.content.ContextCompat

fun checkLocationPermission() {
    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this, arrayOf(Manifest.permission.ACCESS_FINE_LOCATION), REQUEST_LOCATION_PERMISSION)
    } else {
        // 已经拥有权限，可以进行位置请求
    }
}

DispatchQueue.global(qos: .background).async {
    self.locationManager.requestLocation()
}

import kotlinx.coroutines.*

fun requestLocationAsync() {
    GlobalScope.launch(Dispatchers.IO) {
        // 执行位置请求
    }
}
