Build Strava Clone in iOS using MapKit, Realm and UIKit

Create a tab bar controller class to manage home and history tabs, configure tab bar items with system icons, and initialize view controllers with distinct colors, all programmatically.

Create a reusable gradient view with a custom layer and cg color conversion, filling the screen. Use it as the home view background for the map and run button.

Build a circular button as a custom control with configurable border, corner radius, and title styling, and add a location manager to manage authorization for run tracking.

Build a home view with a translucent map, a circular start button, and a centered label; configure location authorization, show user location, and follow user movement with MapKit.

Build the current run view controller with a gradient background, assemble time, base label, distance, and pace UI elements, and integrate a custom slider and stack views with programmatic constraints.

Build a current run view controller that tracks location, updates time and distance, formats pace, and uses a draggable slider with a pan gesture, setting up a Realm-backed logs page.

Create a history view controller featuring a custom history cell that displays total miles, total time, and entry date, with constraints and data source setup for Realm storage.

Integrate Realm to store run data and add a shimmer effect and slide-to-unlock animation while polishing the home and log screens, plus map visualization with pins and run routes.

Install Realm using CocoaPods by editing the podfile, adding RealmSwift and related pods, running pod install, and opening the generated workspace to verify the build.

Define Realm models for run and location with primary key and indexed fields, establish one-to-many relations, and implement add and fetch operations via a queue to persist runs in Realm.

Configure the history table with a cell configure function that takes a run object, formats total miles, duration, and date, and fetches all runs from Realm.

Implement saving runs to Realm, including distance and locations, when stopping a run, while building a shimmered slider UI and a previous run detail view with a map.

Explore implementing previous run details in a Strava clone by rendering an MKPolyline overlay and start/end annotations with MapKit, centering the map, and debugging run duration storage.
