The **Swift Android Working Group** has released a preview of the Swift SDK for Android, marking a major step toward native Swift development on Android.
### Key Features
- **Bi‑directional interoperability** via **swift‑java** — generates safe bindings between Swift and Java/Kotlin automatically.
- Compatible with **Linux**, **macOS**, and **Windows** (installer available for Windows).
- Over **25% of Swift packages** now support Android (Swift Package Index updated with Android compatibility indicators).
- Sample projects and a "Getting Started" guide available to accelerate adoption.
### Community Vision
- Drafting a public vision document.
- Using project boards to track progress.
- Continuous Integration (CI) support for Android builds.
- Welcoming developer participation via the Swift forums.
#### Why It Matters for Cross‑Platform UI
- Non‑native UI often feels unnatural (e.g., Adobe UI on multiple platforms).
- **Flutter** aims for pixel‑perfect iOS reproduction; **React Native** preserves native component feel.
- Swift Android could mirror **Kotlin Multiplatform** — share logic, keep native UI.
- Sharing business logic server‑side via APIs (e.g., GraphQL) works well unless offline use/high latency is critical.

## U.S. Heat Pump Adoption — Challenges & Solutions
**Source:** [Heat Pumped](https://www.heatpumped.org/p/harnessing-america-s-heat-pump-moment)
**HN:** 230 points | 500 comments | Posted 1 day ago
**HN Discussion:** [YCombinator thread](https://news.ycombinator.com/item?id=45698554)
### Main Barriers
- Installation quality, training scarcity, low public awareness.
- Contractor habit bias — tendency to stick with familiar tech.
- Market messaging fragmentation undermines trust.
### Five Adoption Paths
1. Homeowner education.
2. Training new/existing HVAC professionals.
3. Accurate design/installation tools.
4. Policy to phase out single‑direction AC.
5. Mandating heat pumps for new builds.

### Change
- `shutdown.log` now overwritten per reboot — erasing historical forensic evidence.
- Previously critical for detecting Pegasus/Predator spyware artifacts.
- Security researchers recommend:
- Generate/save `sysdiagnose` before upgrading.
- Delay update until Apple addresses detection gap.
