Just fixed a SIGABRT crash in Nitro when using Promises! Hunting down the bug was pretty fun - the inner Promise kept a 𝙿𝚛𝚘𝚖𝚒𝚜𝚎 strong in it's 𝚜𝚝𝚍::𝚏𝚞𝚗𝚌𝚝𝚒𝚘𝚗 capture, causing the 𝙹𝙿𝚛𝚘𝚖𝚒𝚜𝚎 dtor to be called on a wrong Thread! 🤯 github.com/mrousavy/nitro…

Just added support for Android 𝙷𝚊𝚛𝚍𝚠𝚊𝚛𝚎𝙱𝚞𝚏𝚏𝚎𝚛 in Nitro. 🔥 This is super efficient for GPU-based buffers (like Camera Frames) and allows you to read those buffers directly in JS, without performing a copy. 🤯 github.com/mrousavy/nitro…

Swift's new Java interop uses JNI by default, but if the JVM supports the new FFI/FFM mode, it can automatically use this and benefit from much faster performance and lower overhead. This is really cool! #WWDC25

Swift 6.2 brings a new Foundation type; 𝙸𝚗𝚕𝚒𝚗𝚎𝙰𝚛𝚛𝚊𝚢<𝙽, 𝚃>. 📦 This makes use of a new generics feature, where a generic argument is used to define the array's size at compile-time. Pretty neat! #WWDC25
