Executive Summary: Mobil Pazarın Nabzı

2025’te Türkiye’de 5.2 milyon aktif mobil uygulama mevcut. Ortalama bir Türk kullanıcı günde 4.7 saat mobil cihazında vakit geçiriyor. Cross-platform geliştirme, native geliştirmeye göre %40 daha hızlı ve %60 daha ekonomik. Flutter’ın pazar payı %38’e ulaşırken, React Native %32’de kaldı. Ancak şeytan detayda gizli…

2025 Mobil Trendler: Türkiye Perspektifi

1. AI-Powered Mobile Apps

// iOS - Core ML Integration
import CoreML
import Vision

class TextRecognitionService {
    func recognizeTurkishText(from image: UIImage) async throws -> String {
        guard let cgImage = image.cgImage else {
            throw RecognitionError.invalidImage
        }
        
        let request = VNRecognizeTextRequest()
        request.recognitionLanguages = ["tr-TR"]
        request.recognitionLevel = .accurate
        request.usesLanguageCorrection = true
        
        let handler = VNImageRequestHandler(cgImage: cgImage)
        try await handler.perform([request])
        
        guard let observations = request.results else {
            throw RecognitionError.noTextFound
        }
        
        return observations.compactMap { $0.topCandidates(1).first?.string }
            .joined(separator: " ")
    }
}

// Android - ML Kit Integration
class TextRecognitionService {
    private val recognizer = TextRecognition.getClient(
        TextRecognizerOptions.Builder()
            .setExecutor(Executors.newSingleThreadExecutor())
            .build()
    )
    
    suspend fun recognizeTurkishText(image: InputImage): String {
        return suspendCoroutine { continuation ->
            recognizer.process(image)
                .addOnSuccessListener { visionText ->
                    val turkishText = visionText.textBlocks
                        .filter { it.recognizedLanguage == "tr" }
                        .joinToString(" ") { it.text }
                    continuation.resume(turkishText)
                }
                .addOnFailureListener { e ->
                    continuation.resumeWithException(e)
                }
        }
    }
}

2. Super Apps: Türkiye’nin Yeni Trendi

// Mini-app Architecture Example
const SuperAppFramework = {
  miniApps: {
    'banking': {
      bundleUrl: 'https://cdn.app.com/banking.bundle',
      permissions: ['camera', 'biometric'],
      version: '2.3.1'
    },
    'e-commerce': {
      bundleUrl: 'https://cdn.app.com/shopping.bundle',
      permissions: ['location', 'notifications'],
      version: '1.8.2'
    },
    'food-delivery': {
      bundleUrl: 'https://cdn.app.com/food.bundle',
      permissions: ['location', 'phone'],
      version: '3.1.0'
    }
  },
  
  loadMiniApp: async function(appId) {
    const config = this.miniApps[appId];
    const bundle = await fetch(config.bundleUrl);
    const code = await bundle.text();
    
    // Sandbox execution
    const sandbox = new MiniAppSandbox({
      permissions: config.permissions,
      sharedData: this.getUserContext()
    });
    
    return sandbox.execute(code);
  }
};

3. Foldable Devices Support

// Flutter - Foldable screen adaptation
import 'package:dual_screen/dual_screen.dart';

class FoldableLayout extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return TwoPane(
      startPane: ListView(
        children: [
          ListTile(title: Text('Hesaplarım')),
          ListTile(title: Text('Kartlarım')),
          ListTile(title: Text('Ödemeler')),
        ],
      ),
      endPane: Container(
        child: Center(
          child: Text('Detay Görünümü'),
        ),
      ),
      panePriority: TwoPanePriority.both,
    );
  }
}

Güvenlik Best Practices

Code Obfuscation ve Protection

// Android - build.gradle
android {
    buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            
            // Additional security
            buildConfigField "String", "API_KEY", "\"${System.env.API_KEY}\""
        }
    }
}

// proguard-rules.pro
-keep class com.company.app.security.** { *; }
-keepclassmembers class * {
    @android.webkit.JavascriptInterface ;
}

Certificate Pinning

// iOS - Certificate Pinning
class NetworkSecurityManager: NSObject, URLSessionDelegate {
    func urlSession(_ session: URLSession, 
                   didReceive challenge: URLAuthenticationChallenge, 
                   completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) {
        
        guard let serverTrust = challenge.protectionSpace.serverTrust,
              let certificate = SecTrustGetCertificateAtIndex(serverTrust, 0) else {
            completionHandler(.cancelAuthenticationChallenge, nil)
            return
        }
        
        let serverCertData = SecCertificateCopyData(certificate) as Data
        let pinnedCertData = loadPinnedCertificate()
        
        if serverCertData == pinnedCertData {
            completionHandler(.useCredential, URLCredential(trust: serverTrust))
        } else {
            completionHandler(.cancelAuthenticationChallenge, nil)
        }
    }
}
