Performance Optimization Strategies

App Launch Optimization

Cold Start Performance

// iOS: Optimize app delegate methods
func application(_ application: UIApplication, 
                didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Minimize heavy operations
    // Defer non-critical initializations
    // Use lazy loading for resources
    return true
}

Warm Start Optimization

  • Efficient state restoration
  • Optimized view controller lifecycle
  • Memory management best practices
  • Background task optimization

Memory Management

iOS Memory Best Practices

  • Use weak references to avoid retain cycles
  • Implement proper deallocation methods
  • Monitor memory usage with Instruments
  • Optimize image loading and caching

Android Memory Optimization

  • Implement proper lifecycle management
  • Use memory-efficient data structures
  • Optimize bitmap loading and recycling
  • Monitor memory leaks with profiling tools

Security Implementation

Data Protection

Encryption Standards

// Android: Implement secure data storage
val masterKey = MasterKey.Builder(context)
    .setKeyScheme(MasterKey.KeyScheme.AES256_GCM)
    .build()

val sharedPreferences = EncryptedSharedPreferences.create(
    context,
    "secure_prefs",
    masterKey,
    EncryptedSharedPreferences.PrefKeyEncryptionScheme.AES256_SIV,
    EncryptedSharedPreferences.PrefValueEncryptionScheme.AES256_GCM
)

Network Security

  • Certificate pinning implementation
  • HTTPS enforcement
  • API authentication and authorization
  • Secure token management

Authentication Best Practices

Biometric Authentication

  • Touch ID/Face ID integration
  • Fingerprint authentication on Android
  • Fallback authentication methods
  • Secure credential storage

OAuth 2.0 Implementation

  • Secure authorization flows
  • Token refresh mechanisms
  • Scope-based permissions
  • PKCE for mobile apps

Testing Strategies

Automated Testing

Unit Testing

// iOS: XCTest example
import XCTest
@testable import MyApp

class UserServiceTests: XCTestCase {
    func testUserValidation() {
        let userService = UserService()
        let isValid = userService.validateUser(email: "test@example.com")
        XCTAssertTrue(isValid)
    }
}

UI Testing

  • Automated UI test suites
