I fall into the same issue (at least by symptoms).
In my case the problem was in the <code>- (void)applicationWillResignActive:(UIApplication *)application;</code> method, where I was releasing my <code>CLLocationManager</code> instance as part of preparing for background transition. When I removed it and left it only in <code>- (void)applicationDidEnterBackground:(UIApplication *)application;</code> the problem is gone. The tricky part is that Core Location alert DO suspend your application while it still in foreground. Hope that it will help you, took me a lot of time to found that bastard :)

blocks|key|531922|text|虽然很难追踪，但解决方案非常简单。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|531923|通过反复试验，我发现，虽然当你第一次尝试访问应用程序中的任何位置服务时，位置访问对话框会弹出，但如果在用户响应对话框之前释放CLLocationManager对象，该对话框就会自动消失(没有任何用户交互)。|offset|length|style|CODE|531924|我在我的viewDidLoad方法中创建了一个CLLocationManager实例。由于这是该方法的本地实例，因此该实例在该方法完成执行后由ARC释放。实例一释放，对话框就消失了。解决方案相当简单。将CLLocationManager实例从方法级变量更改为类级实例变量。现在，只有在卸载类之后，才会释放CLLocationManager实例。|531925|entityMap^0|0|1Q|H|0|4|B|N|H|2T|H|48|H|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@$D|Q|E|R|F|G]|$D|S|E|T|F|G]|$D|U|E|V|F|G]|$D|W|E|X|F|G]]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|K|$]]

While difficult to track down, the solution for this is quite simple.

Through much trial and error I found out that while the location access dialog pops up when you try to access any location services in the app for the first time, the dialog disappears on its own (without any user interaction) if the <code>CLLocationManager</code> object is released before the user responds to the dialog.

I was creating a <code>CLLocationManager</code> instance in my <code>viewDidLoad</code> method. Since this was a local instance to the method, the instance was released by ARC after the method completed executing. As soon as the instance was released, the dialog disappeared. The solution was rather simple. Change the <code>CLLocationManager</code> instance from being a method-level variable to be a class-level instance variable. Now the <code>CLLocationManager</code> instance is only released once the class is unloaded.

blocks|key|531946|text|我知道这是一个很晚的回复。但这可能会对某些人有所帮助。我也面临着同样的问题，并花了一个小时来确定问题。起初，我的代码是这样的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|531947|CLLocationManager+*locationManager+=+[[CLLocationManager+alloc]+init];

I know this is a very late reply. But it may help someone.
I also faced the same problem and spent an hour to identify the issue.
At first my code was like this.

<pre><code>CLLocationManager *locationManager = [[CLLocationManager alloc] init];
[locationManager startUpdatingLocation];

CLLocation *location = locationManager.location;
//my stuff with the location

 [locationManager release];
</code></pre>

Now the location alert disppeared quickly.
When I uncomment the last line it is working correctly.

<pre><code> // [locationManager release];
</code></pre>

blocks|key|532020|text|我也遇到了这个问题，但我的案例中的解决方案被证明与公认的答案完全不同。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|532021|在我的应用程序中，我从applicationWillResignActive调用stopUpdatingLocation。这是一个问题，因为当出现权限对话框时会调用applicationWillResignActive。这会在startUpdatingLocation之后立即导致stopUpdatingLocation，这就是为什么对话框会立即消失的原因。|offset|length|style|CODE|532022|解决方案只是简单地从applicationDidEnterBackground调用stopUpdatingLocation。|532023|entityMap^0|0|B|R|14|K|2A|R|35|L|3W|K|0|A|T|15|K|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]|$D|P|E|Q|F|G]|$D|R|E|S|F|G]|$D|T|E|U|F|G]|$D|V|E|W|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|X|8|@$D|Y|E|Z|F|G]|$D|10|E|11|F|G]]|9|@]|A|$]]|$1|J|3|-4|5|6|7|12|8|@]|9|@]|A|$]]]|K|$]]

I ran into this problem, also, but the solution in my case turned out to be completely different than the accepted answer.

In my app, I was calling <code>stopUpdatingLocation</code> from <code>applicationWillResignActive</code>. This was a problem because <code>applicationWillResignActive</code> is called when the permission dialog appears. This was causing <code>stopUpdatingLocation</code> immediately after <code>startUpdatingLocation</code>, which is why the dialog would immediately disappear.

The solution was simply to call <code>stopUpdatingLocation</code> from <code>applicationDidEnterBackground</code> instead.

blocks|key|532025|text|您最常将locationManager变量定义为全局对象。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|532026|@interface+ViewController+:+UIViewController

blocks|key|748468|text|这发生在我使用iOS模拟器的时候。我确定它的发生是因为我的Run+Scheme正在模拟一个位置。我认为这与在启动时调用locationManager.startUpdatingLocation()具有相同的效果，因此它关闭了对话框。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|748469|在编辑方案对话框中取消选中“允许位置模拟”复选框已修复此问题。一旦它按照您希望的那样工作，并且设置了权限，您就可以重新启用位置模拟，模拟器从此就可以正常工作了。|748470|entityMap^0|1N|13|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|N|8|@]|D|@]|E|$]]]|I|$]]

This was happening to me while using the iOS Simulator. I determined that it was occurring because my Run Scheme was simulating a location. I think this has the same effect as calling <code>locationManager.startUpdatingLocation()</code> at launch and so it was closing the dialog.

Un-checking the "Allow Location Simulation" checkbox in the Edit Schemes dialog fixed the issue. Once it works as you want it to and the permission is set, you can re-enable the location simulation and the simulator will work fine from then on.

I have faced the similar situation. After debugging I found 

<pre><code>let locationManager = CLLocationManager()
</code></pre>

is called in a method scope, but it should be called globally.

Why?

In a nutshell, locationManager has been released after the method had returned. But it shouldn't be released until user give or deny permission

I had the <code>locationManager</code> as instance var but still that did not help in Swift 5, Xcode 11 (see below):
<pre><code>class MapViewController: UIViewController {
 
 var locationManager: CLLocationManager {
 let locationManager = CLLocationManager()
 locationManager.desiredAccuracy = .greatestFiniteMagnitude
 locationManager.delegate = self
 locationManager.requestWhenInUseAuthorization()
 return locationManager
 }
 
 override func viewDidLoad() {
 super.viewDidLoad()
 locationManager.startUpdatingLocation()
 }
}
</code></pre>
However, making <code>locationManager</code> var lazy fixed the issue:
<pre><code>class MapViewController: UIViewController {

 lazy var locationManager: CLLocationManager = {
 let locationManager = CLLocationManager()
 locationManager.desiredAccuracy = .greatestFiniteMagnitude
 locationManager.delegate = self
 locationManager.requestWhenInUseAuthorization()
 return locationManager
 }()

 override func viewDidLoad() {
 super.viewDidLoad()
 locationManager.startUpdatingLocation()
 }
}
</code></pre>

My app takes the user's location, gets the co-ordinates , and provides a distance to or from their destination or origin. All these possible destinations are shown in a table view, so I'm getting the users co-ordinates at the same time as populating the table. The only thing is, the alert view that asks for the users location appears then disappears so quickly it's impossible to click it!

Is there any way to manually present this alert when the app first loads? I tried getting the user's location when the app loads up to try and force the alert to show, but that didn't work.

Current location permission dialog disappears too quickly
