+**Core Components:** +- **Foundation Extensions**: 15+ utility categories (NSString, NSDate, NSDictionary, etc.) +- **Core Types**: Complex enum definitions, state machines, callback typedefs (579-line ARTTypes.h) +- **Authentication**: Token-based auth with callback patterns +- **Networking**: HTTP client with fallback hosts, custom SSL handling +- **Messaging**: Message encoding/decoding with multiple formats (JSON, MsgPack, Delta Codec) +- **Real-time**: WebSocket transport with connection state management +- **Channels**: REST and Realtime channel implementations with presence +- **Push Notifications**: iOS-specific push registration and device management +- **Client Classes**: ARTRest and ARTRealtime main entry points + +**External Dependencies:** +- SocketRocket (WebSocket implementation) +- msgpack-objective-c (Binary encoding) +- delta-codec-cocoa (Message compression) +- ably-cocoa-plugin-support (Plugin architecture) + +## Migration Strategy + +### Approach:

Exception Handling +```objective-c +// Current Objective-C pattern +@throw [NSException exceptionWithName:@"InvalidArgument" reason:@"..." userInfo:nil]; +``` + +Swift replacement: + +```swift +fatalError("InvalidArgument: ...") +``` + +#### 2. Error Handling Pattern +```objective-c +// Objective-C NSError** pattern +- (id)methodWithError:(NSError **)error { + // implementation +} +``` + +Swift replacement: + +```swift +// Swift throws pattern +func method() throws -> SomeType { + // implementation +} +``` + +#### 2. Atomic Properties +```objective-c +// Current usage (found in ARTGCD.m) +@property (atomic, copy, nullable) dispatch_block_t block; +``` + +Swift equivalent: + +```swift +// Lock that implements the equivalent of Objective-C `atomic` for the `block` property +private let _blockLock = NSLock() +private var _block: DispatchWorkItem? +var block: DispatchWorkItem? { + get { _blockLock.withLock { _block } } + set { _blockLock.withLock { _block = newValue } } +} +``` + +#### 3. Logging Macros Migration + +Current extensive usage of logging macros throughout codebase: + +```objective-c +ARTLogError(logger, @"Error message: %@", error); +ARTLogWarn(logger, @"Warning: %@", message); +ARTLogInfo(logger, @"Info: %@", info); +ARTLogDebug(logger, @"Debug: %@", debug); +ARTLogVerbose(logger, @"Verbose: %@", verbose); +``` + +We will implement these Objective-C macros as Swift functions, injecting the `#fileID` and `#line` values using default arguments: + +```swift +func ARTLogError(_ logger: ARTInternalLog, _ message: String, fileID: String = #fileID, line: Int = #line) + logger.log(level: .error, file: fileID, line: line, message: message) +} +``` + +At the call site, instead of using varargs, we will use Swift string interpolation to pass a single message string to the logger. + +**CRITICAL REQUIREMENT: Pointer Formatting Support** + +For log statements that use `%p` format specifiers in Objective-C (to log pointer addresses), create a custom string interpolation extension: + +```swift +// StringInterpolationExtensions.swift +extension String.StringInterpolation { + mutating func appendInterpolation(pointer: T) { + let address = Unmanaged.passUnretained(pointer).toOpaque() + appendLiteral(String(format: "%p", Int(bitPattern: address))) + } + + mutating func appendInterpolation(pointer: T?) { + if let pointer = pointer { + let address = Unmanaged.passUnretained(pointer).toOpaque() + appendLiteral(String(format: "%p", Int(bitPattern: address))) + } else { + appendLiteral("(null)") + } + } +} +``` + +**Migration Pattern for Logging:** + +```objective-c +// Objective-C +ARTLogDebug(self.logger, @"R:%p C:%p (%@) received message %tu", _realtime, self, self.name, message.action); +``` + +```swift +// Swift - use string interpolation with pointer support +ARTLogDebug(logger, "R:\(pointer: realtime) C:\(pointer: self) (\(self.name)) received message \(message.action.rawValue)") +``` + +**Key Points:** +- **NO varargs**: Never use variadic arguments in Swift logging calls +- **Single string parameter**: Always pass a single interpolated string to logging functions +- **Pointer formatting**: Use `\(pointer: obj)` for objects that were logged with `%p` in Objective-C +- **String interpolation**: Use Swift's native string interpolation for all other format specifiers + +#### 4. Nullability Analysis Required +- **Header Interfaces**: Some may have incorrect nullability annotations +- **Local Variables**: Need to determine proper optionals for local vars +- **Generic Collections**: Need to resolve generic type arguments for dictionaries/arrays + +#### 5. Foundation Type Migration + +Objective-C: + +```objective-c +NSString *name; +NSMutableDictionary *dict; +NSDate *timestamp; +``` + +```swift +var name: String +var dict: [String: Any] // as an example — in reality, use whichever generic arguments are appropriate +var timestamp: Date +``` + +### Access Control Mapping + +**Current Objective-C Structure:** +- **`Sources/Ably/include/`**: Public headers forming the public API +- **`Sources/Ably/PrivateHeaders/`**: Private headers with internal declarations +- **`.m` implementation files**: Implementation-only declarations + +**Swift Access Control Decision Rule:** + +All declarations (classes, methods, properties, types, etc.) inherit their access level from their original declaration location: + +- **Declarations from `Sources/Ably/include/`** → `public` +- **Declarations from `Sources/Ably/PrivateHeaders/`** → `internal` +- **Declarations only in `.m` files** → `private` + +**Swift Access Control Examples:** +```swift +// Example 1: Public API (from Sources/Ably/include/ARTRealtime.h) +public class ARTRealtime { + public func connect() { } // Declared in include/ header +} + +// Example 2: Internal API (from Sources/Ably/PrivateHeaders/ARTRealtime+Private.h) +extension ARTRealtime { + internal func internalConnect() { } // Declared in PrivateHeaders/ +} + +// Example 3: Private implementation (from ARTRealtime.m only) +extension ARTRealtime { + private func helperMethod() { } // Only exists in .m file +} + +// Example 4: Internal types (from Sources/Ably/PrivateHeaders/ARTInternalHelper.h) +internal class ARTInternalHelper { } // Declared in PrivateHeaders/ +``` + +**Decision Algorithm for LLM Implementation:** +1. **Check declaration location**: Look up where each method/property/type is originally declared +2. **Apply access level**: Use the location-based rule above +3. **Consistency check**: Ensure all members of a type follow the same pattern based on their original declaration location + +### Swift-Specific Requirements + +#### 1. Interface Priority +- **Favor header declarations over implementation** - headers more likely to have correct nullability and be accurate +- Use header interfaces as the source of truth for method signatures + +### Low-Hanging Swift Improvements + +While maintaining carbon-copy behavior, these Swift idioms can be adopted: + +#### 1. Foundation Type Modernization +```objective-c +// Avoid in Swift +var items: NSMutableArray +var properties: NSMutableDictionary +var identifier: NSString + +// Use instead +var items: [SomeType] +var properties: [String: Any] +var identifier: String +``` + +#### 2. Functional Programming Patterns +```objective-c +// Replace manual array building +NSMutableArray *results = [NSMutableArray new]; +for (Item *item in items) { + [results addObject:[self processItem:item]]; +} + +// With functional equivalent +let results = items.map { processItem($0) } +``` + + +### File Organization + +**Proposed Structure:** +``` +Sources/ +├── Ably/ # Existing Objective-C (keep during transition) +├── AblySwift/ # New Swift implementation +│ ├── MigrationPlaceholders.swift # Temporary placeholder types +│ ├── ARTAnnotation.swift +│ ├── ARTAttachRequestParams.swift +│ ├── ARTAuth.swift +│ ├── ...

Inheritance**: Always check if placeholder classes should inherit from other types + - Example: `ARTClientOptions` inherits from `ARTAuthOptions` in original code + - Missing inheritance relationships will cause type errors during migration + +**Placeholder Removal:** Remove placeholder types from `MigrationPlaceholders.swift` once proper implementation exists + +### Code Comment Guidelines + +**Migration Comments:** All migration-related code comments MUST start with `swift-migration: ` so that a human reviewer can distinguish them from the original Objective-C comments + +**Required Comments:** +- **Source Location**: Before each migrated entity (class, method, property, enum, etc.), add a comment indicating its original location: `// swift-migration: original location Foo.m, line 123` + - **IMPORTANT**: This comment must appear BEFORE any documentation comments or original Objective-C comments + - **CRITICAL REQUIREMENT - For entities with both declaration and definition**: Include both locations: `// swift-migration: original location Foo.h, line 45 and Foo.m, line 123` + - **How to Check**: Before writing the comment, search both the header files (.h, +Private.h) and implementation file (.m) to verify if the entity is declared in headers + - **Examples**: + - Method declared in ARTAuth+Private.h line 106 and implemented in ARTAuth.m line 798: `// swift-migration: original location ARTAuth+Private.h, line 106 and ARTAuth.m, line 798` + -

these may be inherited from parent classes or implemented elsewhere +- **If a header declares something not implemented in the .m file**: Document this in migration notes, do not implement it +- **ALL explanatory comments about what you're doing must have `swift-migration:` prefix** + +**Source Location Comment Format:** +```swift +// swift-migration: original location ARTAuth.m, line 45 +/// Authenticates the user with the given callback +/// -

Identify conflicting nullability assumptions between different Objective-C declarations + - Confirm original Objective-C code was designed to handle nil for that parameter + - Only then use the utility function: + + ```swift + // ONLY when direct port fails due to conflicting nullability assumptions + func someMethod(_ param: ParamType?) -> ReturnType { + // swift-migration: Using utility due to conflicting nullability assumptions in original code + return originalMethod(param: unwrapValueWithAmbiguousObjectiveCNullability(param)) + } + ``` + +3. **NEVER create fallback objects** (e.g., `param ?? DefaultObject()`) as this changes runtime behavior + +**Common nullability assumption conflicts:** +- Protocol declares parameter as `nullable` but implementing method is in `NS_ASSUME_NONNULL_BEGIN/END` +- One part of API explicitly allows nil, another part assumes non-null via compiler directives +- Method signature assumptions conflict with actual usage patterns in the codebase + +**Requirements for using `unwrapValueWithAmbiguousObjectiveCNullability`:** +- ✅ Direct porting attempt failed with compilation error +- ✅ Identified conflicting nullability assumptions in original Objective-C +- ✅ Your Swift method correctly accepts optional parameter +- ✅ Original Objective-C code was designed to handle nil despite assumptions +- ✅ Must document the specific conflict with `swift-migration:` comment + +**Platform Conditionals:** +```objective-c +// Objective-C +#if TARGET_OS_IOS + +// Swift +#if os(iOS) +``` + +**NSMutableArray Queue Operations:** + +Do not migrate the following methods; instead just use the following at the call sites in `ARTRealtime`: + +- `NSMutableArray.art_enqueue` → `Array.append` +- `NSMutableArray.art_dequeue` → `Array.popFirst` +- `NSMutableArray.art_peek` → `Array.first` + +**NSMutableDictionary Parameters:** +- Methods accepting `NSMutableDictionary` → Accept `inout Dictionary` in Swift +- Examples: `ARTMessageOperation.writeToDictionary:`, `ARTJsonLikeEncoder.writeData:…` + +**Enum Value Migration:** + +When migrating Objective-C constant references to Swift enum cases, use the proper Swift enum syntax: + +```objective-c +// Objective-C constants +ARTStateRequestTokenFailed +ARTErrorTokenErrorUnspecified +ARTErrorIncompatibleCredentials +``` + +```swift +// Swift enum cases +ARTState.requestTokenFailed.rawValue +ARTErrorCode.tokenErrorUnspecified.rawValue +ARTErrorCode.incompatibleCredentials.rawValue +``` + +**Migration Pattern:** +- `ARTState*` constants → `ARTState.camelCase.rawValue` +- `ARTError*` constants → `ARTErrorCode.camelCase.rawValue` +- Always use `.rawValue` to get the underlying integer value +- Convert PascalCase to camelCase for Swift enum cases + +### NSCopying Protocol Translation + +**The Challenge:** +Objective-C's `NSCopying` protocol requires implementing `copyWithZone:` which returns `id`.

Callbacks that are stored or called asynchronously must be marked as `@escaping`. + +**Common Patterns Requiring @escaping:** + +1. **Typealias Definitions:** +```swift +// ❌ INCORRECT - callback will be captured in async contexts +public typealias ARTAuthCallback = (ARTTokenParams?, ARTTokenDetailsCompatibleCallback) -> Void + +// ✅ CORRECT - mark nested callback as @escaping +public typealias ARTAuthCallback = (ARTTokenParams?, @escaping ARTTokenDetailsCompatibleCallback) -> Void +``` + +2. **Method Parameters:** +```swift +// Methods that store or async-dispatch callbacks need @escaping +internal func authenticate(_ callback: @escaping ARTTokenDetailsCallback) { + userQueue.async { + // callback used in async context - needs @escaping + callback(result, error) + } +} +``` + +3. **Nested Callback Scenarios:** +```swift +// When callbacks are passed to user code that may store them +let userCallback: ARTAuthCallback = { tokenParams, callback in + self.userQueue.async { + // callback parameter needs @escaping in typealias + authCallback(tokenParams, callback) + } +} +``` + +**Migration Strategy:** +- **Immediate Fix**: Add `@escaping` to callback typealiases and method parameters as compilation errors arise +- **Retroactive Updates**: Previously migrated files may need `@escaping` additions when new migrations depend on them +- **Document Changes**: Use `swift-migration:` comments when adding `@escaping` to existing signatures + +**Example Retroactive Fix:** +```swift +// Original migration +internal func authorize(_ callback: ARTTokenDetailsCallback) // Missing @escaping + +// Fixed after compilation error in dependent file +// swift-migration: Added @escaping for callback compatibility with new migrations +internal func authorize(_ callback: @escaping ARTTokenDetailsCallback) +``` + +## Risk Assessment & Mitigation + +### High-Risk Areas + +1. **State Machine Complexity** + -
