Navigation applications have been impacted by iOS 14's introduction of Approximate Location mode, which reduces the precision of location data shared with applications, affecting functionalities such as route recalculation and speed monitoring. To address these challenges, developers need to upgrade to version 1.0 of the Mapbox Navigation SDK for iOS, which is designed to support iOS 14's Location Services functionality while maintaining data fidelity and navigation accuracy. Approximate Location mode alters how frequently an application detects a driver's location, causing potential usability issues like inaccurate vehicle movement tracking. The update allows developers to use new APIs to manage location accuracy and request temporary access to precise location data when needed. The upgrade ensures that navigation applications can continue to provide reliable services despite the changes in location data handling introduced by iOS 14.
