distanceInMeters Problems with arrays and sort

Question

I want to sort my TableView by distance, but I have mixed up:( Please help me if You can, I would appreciate it, really :(

I have an array with 100 objects.

Answer 1

Use of unresolved identifier 'mall'

=> There is nothing named "mall" in the scope of the function locationManager didUpdateLocations. Meaning: locationManager didUpdateLocations has no clue what happens inside of tableView cellForRowAt indexPath and vice versa.

You could solve this problem by applying following steps to your code:

1. Move the distance calculation from
   locationManager didUpdateLocations
   to
   tableView cellForRowAt indexPath

2. add a property to your class that stores the current position:
   var currentPosition: CLLocation? = nil

3. Store the position you receive in locationManager didUpdateLocations to the currentPosition property

4. Add self.tableView.reloadData() after you received and assigned the position
5. Use the mall and the currentPosition in cellForRowAt to calculate the distance and update the distanceLabel
6. Keep in mind that currentPosition can be nil and the distance can not be calculated => make label empty or add something like "unknown distance" to it
