No events planned for July, but we do have some exciting news coming, starting with...

What we're building

๐Ÿค– Reaper for Android

Reaper for Android is working E2E ๐Ÿ™Œ. For those unfamiliar, the Reaper SDK finds unused code based on production runtime analysis. Previously only available on iOS, we will be opening up a beta for Android soon ๐ŸŽ‰

๐Ÿ“ธ Optimize Alternative Icons

Alternative app icons are never shown to a user above a 180x180 px resolution but must be submitted in 1024x1024 resolution. This new Size Analysis insight will downscale any alternate icons to 180x180 and then upscale it to 1024x1024, saving size from the bundled image. With the new iOS 18 icon features, something tells us that teams will start playing around with icons even more. This new insight will help prevent app size bloat.

๐ŸŽ–๏ธ Compose Preview Parameters on Snapshots

Emerge's Android Snapshots now show what parameters Compose Previews have set in our UI, like font scale or locale ๐ŸŒ. This helps make it even easier to know what you're reviewing and where exactly a diff is coming from.

What we're writing

โš–๏ธ SwiftData vs Realm: Performance Comparison

How does the speed of Realm compare to SwiftData? What about memory usage? Size? Does the answer change if the data object is complex or simple? Wonder no more ๐Ÿค“
