Current location permission dialog disappears too quickly

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 CLLocationManager object is released before the user responds to the dialog.

I was creating a CLLocationManager instance in my viewDidLoad 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 CLLocationManager instance from being a method-level variable to be a class-level instance variable. Now the CLLocationManager instance is only released once the class is unloaded.

Same symptom, different cause: do not to call startUpdatingLocation more than once in a row.

I had accidentally structured things such that the code was unintentionally calling startUpdatingLocation twice in a row, which is apparently bad. It might also have had something to do with choice of queue since I was waiting to start updating pending the result of a network request, but I didn't need to do any GCD magic to fix it...just needed to make sure I didn't repeat the start.

Hope someone's able to benefit from my pain. :)

I have faced the similar situation. After debugging I found

let locationManager = CLLocationManager()

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
