New SkyDeck feature posting your growth graph on Bluesky
Total follower growth graph.
The image compares three different approaches for associating 5000 Post objects with an Author object in Swift, using SwiftData. On the left, Swift code is shown: 1. Append individually โ€“ each Post is created and directly appended to author.posts. 2. Assign author reference โ€“ each Post is created and has its .author property set to author. 3. Batch append with contentsOf: โ€“ all posts are first created in an array, then added to author.posts in one step using append(contentsOf:). On the right, a bar graph compares the performance of the three methods: โ€ข Append takes 11.788ms โ€ข Assign takes 1.510ms โ€ข contentsOf takes 1.320ms The graph visually emphasizes the inefficiency of individual append operations compared to batched or reference-based association.
Screenshot of the Post Performance view in the Skydeck app on an iPhone. It features a sheet interface with filters for time range (e.g., This week, This month) and engagement metrics (e.g., Like, Reply, Repost), as well as options to filter posts by type (Posts only, Posts & Replies, All).
Three screenshots of the Post Performance feature in a mobile app. The first screenshot shows a drop-down menu for selecting time filters: 'All time,' 'This week,' 'This month,' and 'This year.' The second screenshot displays filter options above the post list: checkboxes for 'Posts only,' 'Posts and Replies,' and 'All.' The third screenshot illustrates a 'Filter only' dropdown menu, showing filter categories like Likes, Replies, Reposts, and Quotes. Each screen has a clean, modern user interface with tabs at the bottom for navigation.
