Waypoints

Easy location tracking in Swift.

• Add multiple observers for a single location change.
• Configure the minimum distance before a new location is published.
• Supports reverse geocoding.
• Target iOS or macOS.

Usage

Create a LocationTracker instance:

let locationTracker = LocationTracker()

Subscribe to location changes:

locationTracker
    .locationUpdatePublisher
    .sink { [weak self] (result) in
        switch result {
        case .success(let location):
            // handle new location
        case .failure(let error):
            // handle error
        }
    }
    .store(in: &cancellables)

The location is returned as a Result<Location, Error> type, representing either the Location or an Error about why the location could not be obtained.

The Location type combines a CLLocation with metadata for the associated city and state. Address information is obtained using CLGeocoder.

public struct Location {
    let physical: CLLocation
    let city: String
    let state: String
}

Requirements

• Xcode 12
• Swift 5
• iOS 13, macOS 11

Installation

Clone the repo directly and copy LocationTracker.swift into your Xcode project.

Configuration

Starting in iOS 8, the privacy settings require you to specify why the location is needed before the app is authorized to use it. Add an entry into the Info.plist for NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription.

If location is only required when app is active.

<key>NSLocationWhenInUseUsageDescription</key>
<string>Location required because...</string>

If the location is always required.

<key>NSLocationAlwaysUsageDescription</key>
<string>Location always required because...</string>
