3. CocoaPods: Cara Kerja Mendalam

# Podfile — letakkan di root project

# Platform minimum
platform :ios, '16.0'

# Gunakan static frameworks — lebih cepat launch time
use_frameworks! :linkage => :static

# Opsi global
install! 'cocoapods',
  :deterministic_uuids => false,
  :warn_for_unused_master_specs_repo => false

# Target utama
target 'MyApp' do
  # Dependency dengan versi constraint
  pod 'Alamofire', '~> 5.9'          # ~> = compatible dengan (>=5.9, <6.0)

  pod 'Lottie', :git => 'https://github.com/airbnb/lottie-ios.git',

  pod 'SnapKit', '5.7.1'             # exact version
  
  # Pod dari path lokal (untuk library internal)
  pod 'MyInternalSDK', :path => '../MyInternalSDK'
  
  # Pod dengan subspecs
  pod 'Firebase/Analytics'
  pod 'Firebase/Crashlytics'
  pod 'Firebase/Messaging'
  
  # Target test — pod hanya untuk testing

    pod 'Nimble', '~> 13.0'
    pod 'OHHTTPStubs/Swift', '~> 9.0'

# pod install: HANYA install pod baru atau yang berubah di Podfile
# Menggunakan Podfile.lock untuk versi yang sudah ada
pod install

# pod update: UPDATE semua pod ke versi terbaru yang diizinkan constraint
pod update

# pod update spesifik satu pod
pod update Alamofire

# pod install dengan verbose (debug masalah)
pod install --verbose

# pod install tanpa update repo specs (lebih cepat di CI)
pod install --no-repo-update

# Cek outdated pods
pod outdated

# Validate podspec
pod spec lint MyLibrary.podspec --verbose
pod lib lint --allow-warnings

# ✅ COMMIT ke Git:
Podfile
Podfile.lock       # PENTING: lock file memastikan semua developer pakai versi sama

# ❌ JANGAN commit (tambahkan ke .gitignore):
Pods/              # Folder ini besar dan bisa di-regenerate
*.xcworkspace      # Bisa di-regenerate dengan pod install

# .gitignore untuk CocoaPods
Pods/
*.xcworkspace
