Play blocks updates from August 31, 2026 unless the app targets API 36. Bump compileSdk/targetSdk to 36 in :app and :baselineprofile, and AGP to 8.10.1 -- 8.7.3 cannot build against API 36. Gradle stays at 8.11.1, which is what AGP 8.10 requires. Nothing in the app relies on the behaviours Android 16 changed: edge-to-edge is already opted in via enableEdgeToEdge(), the manifest pins no orientation or resizability, and the two bundled native libraries (graphics-path, datastore_shared_counter) are already 16 KB page aligned. Align the version with iOS (1.8.1, code 88) so the API 36 build can ship.
Cable
Cable is a SwiftUI app for laying out low voltage electrical systems. It helps you size conductors, manage saved loads, and browse the VoltPlan component library so you can assemble accurate bills of materials for off-grid or mobile installs.
Requirements
- macOS with Xcode 15 or newer
- iOS 17 simulator (iPhone 15 target used in CI)
- SwiftData and SwiftUI are bundled with the Xcode toolchain; no additional dependencies are required
Getting Started
open Cable.xcodeprojlaunches the project with the correct scheme configuration- Alternatively run
xed Cable.xcodeprojfrom Terminal to open the project in Xcode - Select the Cable scheme and the iPhone 15 simulator, then press Run
Build & Test from the Command Line
- Build:
xcodebuild -scheme Cable -destination 'platform=iOS Simulator,name=iPhone 15' build - Test (unit + UI bundles):
xcodebuild -scheme Cable -destination 'platform=iOS Simulator,name=iPhone 15' test - Clean derived data if Xcode caches cause issues:
xcodebuild -scheme Cable clean

Core Features
- Interactive cable sizing calculator with support for metric and imperial unit systems
- SwiftData-backed storage for electrical systems and saved loads
- Remote VoltPlan component library with searchable affiliate links
- Onboarding flows that guide new users through system setup and load entry
Development Tips
- Stick to idiomatic Swift style: four-space indentation, trailing commas on multiline collections, and
UpperCamelCase/lowerCamelCasenaming - Keep SwiftUI view files focused on a single primary view; extract helpers when logic grows
- Run the test targets before opening a pull request to maintain coverage
- Commit messages should be short, imperative phrases (e.g.,
Update library paging)
