Objective-C Project Rules

Agent Automation Commands

CRITICAL: Execute these commands after EVERY implementation (see AGENT_AUTOMATION module for full workflow).

# Complete quality check sequence:
xcodebuild clean build    # Build verification
xcodebuild test -scheme YourScheme  # All tests
# clang static analyzer runs automatically in Xcode builds

# Security audit:
# Use Xcode's built-in analyzer or third-party tools

Objective-C Configuration

CRITICAL: Use Modern Objective-C with ARC and strict warnings.

• Version: Xcode 15+
• ARC: Automatic Reference Counting required
• Formatter: clang-format
• Testing: XCTest
• Analyzer: clang static analyzer

Code Quality Standards

Mandatory Quality Checks

IMPORTANT: These commands MUST match your GitHub Actions workflows!

# Pre-Commit Checklist (MUST match .github/workflows/*.yml)

# 1. Format check (matches workflow)
clang-format --dry-run --Werror **/*.{h,m}

# 2. Static analysis (matches workflow)
xcodebuild analyze -scheme YourScheme -sdk iphonesimulator

# 3. Build (matches workflow)
xcodebuild build -scheme YourScheme -sdk iphonesimulator \
  ONLY_ACTIVE_ARCH=NO CODE_SIGN_IDENTITY="" CODE_SIGNING_REQUIRED=NO

# 4. Run tests (matches workflow)
xcodebuild test -scheme YourScheme -sdk iphonesimulator \
  -destination 'platform=iOS Simulator,name=iPhone 15'

# If ANY fails: ❌ DO NOT COMMIT - Fix first!

Why This Matters:

• Example: Using clang-format -i locally but --dry-run in CI = failure

Testing Example (XCTest)

@import XCTest;
#import "DataProcessor.h"

@interface DataProcessorTests : XCTestCase
@property (nonatomic, strong) DataProcessor *processor;
@end

@implementation DataProcessorTests

- (void)setUp {
    [super setUp];
    self.processor = [[DataProcessor alloc] initWithThreshold:0.5];
}

- (void)testProcessValidInput {
    NSArray *input = @[@1, @2, @3];
    NSArray *result = [self.processor process:input];
    
    XCTAssertNotNil(result);
    XCTAssertGreaterThan(result.count, 0);
}

- (void)testProcessHandlesNil {
    XCTAssertThrows([self.processor process:nil]);
}

@end
