How Da Lenslist is built

Da Lenslist collects thousands of community-made lenses for Snapchat in one browsable, searchable catalogue. Users unlock, favourite, share and submit lenses, with a subscription that removes ads and unlocks everything.

Architecture

An Objective-C UIKit app with an MVVM-style split, Firebase for accounts and a remote catalogue rendered with cached images and video.

  1. UI

    UIKit view controllers with carousels, shimmering placeholders and popup controllers.

  2. Media

    SDWebImage with SVG coding for previews and an AVPlayer cache for lens videos.

  3. Backend

    Firebase Auth and Analytics; push notifications and background fetch keep the feed fresh.

  4. Monetisation

    Auto-renewable subscription with StoreKit and Google Mobile Ads for free users.
