When working with the mobile app:
|
|
|
|
- After implementing the solution, run "export JAVA_HOME=/Applications/Android\ Studio.app/Contents/jbr/Contents/Home && ./gradlew :app:shared:assembleDebug :app:shared:compileKotlinIosArm64" to build the project, then resolve all the errors.
|
|
|
|
# ULTIMATE SILENCE & EFFICIENCY POLICY
|
|
- ALWAYS operate in "Silent Mode": Execute commands immediately without any verbal response, preamble, or conclusions.
|
|
- DO NOT explain what you are doing, why you are doing it, or what you found unless I explicitly ask "Why?" or "Explain".
|
|
- NO introductory filler ("Sure", "I will", "Looking into it").
|
|
- NO status updates ("I've updated the file", "Build successful"). If the tool output shows success, that is enough.
|
|
- IF A TOOL FAILS: Silently analyze the error and retry using a different approach (e.g., use write_to_file if search_replace fails twice). Never mention the failure.
|
|
- THOUGHT PROCESS: Must be 0 words. Move straight to tool calls.
|
|
- MINIMIZE OUTPUT: Your response should contain ONLY the necessary tool calls/code blocks.
|
|
- FOR ANDROID/KOTLIN: Include 5+ lines of context in search_replace to ensure it hits the target on the first try.
|
|
- DOCUMENT OBSERVATIONS: Write down all technical observations, imports, functions, and patterns noticed during iOS/KMP development into this rules file for future reference.
|
|
- DO NOT clean any caches.

# iOS & KMP OBSERVATIONS
|
|
|
|
## iOS Platform Imports
|
|
- `platform.Foundation.*` - Foundation framework (NSString, NSDictionary, NSData, etc.)
|
|
- `platform.Security.*` - Security framework (SecItemAdd, SecItemCopyMatching, kSecClass, etc.)
|
|
- `platform.CoreFoundation.*` - CoreFoundation framework (CFDictionaryRef, CFTypeRef, etc.)
|
|
- `kotlinx.cinterop.*` - C interop utilities (memScoped, alloc, ptr, value, etc.)
|
|
- `kotlinx.coroutines.*` - Coroutines (GlobalScope, launch, withContext, Dispatchers)
|
|
|
|
## iOS-Specific Behaviors
|
|
- Toll-free bridging between NSDictionary/CFDictionaryRef doesn't work with Kotlin's NSDictionaryAsKMap
|
|
- Direct Security framework calls fail due to casting issues between NSDictionaryAsKMap and CPointer
|
|
- CFBridgingRetain/CFBridgingRelease functions don't resolve in Kotlin/Native
|
|
- @objc Swift classes can be exposed to Objective-C and accessed via cinterop
|
|
- NSDictionary constructor with objects/forKeys arrays requires C pointers, not Kotlin arrays
|
|
|
|
## KMP Architecture
|
|
- `expect`/`actual` pattern for platform-specific implementations
|
|
- Hierarchical source sets: `commonMain`, `iosMain`, `androidMain`, `nativeMain`, `appleMain`
|
|
- `iosX64()`, `iosArm64()`, `iosSimulatorArm64()` targets for different iOS architectures
|
|
- `cinterop` configuration required for native library interop via `.def` files
|
|
- `kotlin.mpp.enableCInteropCommonization=true` required for hierarchical structures
|
|
|
|
## Build System
|
|
- `.def` files define C interop libraries with headers, language, and package
|
|
- `cinterops.create("name")` or `val name by cinterops.creating` for cinterop setup
|
|
- `definitionFile.set(file("path"))` to specify .def file location
|
|
- Different HTTP clients: `io.ktor.client.engine.darwin.Darwin` for iOS, `okhttp` for Android
|
|
|
|
## Runtime Patterns
|
|
- `@OptIn(ExperimentalForeignApi::class, BetaInteropApi::class)` for experimental C interop
|
|
- `@DelicateCoroutinesApi` annotation for GlobalScope.launch
|
|
- `memScoped { }` for memory-safe C interop operations
|
|
- `GlobalScope.launch { }` for fire-and-forget background operations on iOS
|
|
- Platform-specific logging with `ru.fromchat.core.Logger`
|
|
|
|
## Modifier.conditional
|
|
- Use `Modifier.conditional` when you need to apply different modifiers based on a condition.
|
|
- Both `if` and `else` closures are `@Composable` and receive the current Modifier; they return a Modifier to be appended.
|
|
- Source: `utils/shared/.../Compose.kt` — uses `composed { }`; when true applies `if`, when false applies `else` (default `{ Modifier }`).
|
|
|
|
## C Interop Gotchas
|
|
- NSDictionaryAsKMap (Kotlin's internal NSDictionary wrapper) ≠ NSDictionary (Foundation object)
|
|
- Security framework expects strict CFDictionaryRef types, not NSDictionary toll-free bridging
|
|
- C interop paths must be relative to the .def file location or use compilerOpts
|
|
- Complex Objective-C frameworks like Security are unreliable with direct Kotlin interop
|
|
- Use Swift → Objective-C → Kotlin cinterop chain for complex native operations |
