Save longitude and latitude in SQLite database?

You can use a timer and set time interval to 300, as shown below.

I doubt you really always want to store the coordinates every 5 minutes. When using Core Location you subscribe to events that the user has changed position (and you can set accuracy) so you can get notified when the user has moved at all, and then choose to store the coordinates in a database. If you don't get events, then you know the user hasn't changed position.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
