   Fastlane while
   watching Netflix
   (Please don't judge me)

4. Why?
   TL;DL: Because you could be doing something else

5. Command line tools are usually...
   • Boring*
   • Hard to use (intuitively)
   • Hard to script (properly)
   • Hard to maintain (by the next one)
   Apple's are no exception
   (* Except Carthage, Carthage we like.)

6. Let's build an app
   (litteraly)

7. Building an app
   xcodebuild -project Rewatch.xcodeproj \
   -scheme Rewatch \
   -configuration QA \
   CONFIGURATION_BUILD_DIR="$CWD/build" clean build
   • 7 actions (clean, build, archive...)
   • 39 options
   • Terrible error reporting (usually
   "error 65")

8. Packaging the app
   into an IPA
   xcrun -sdk iphoneos \
   PackageApplication "$CWD/build/Rewatch.app" \
   -o "$CWD/build/Rewatch.ipa"
   • Huge perl script
   • (Don't laught, perl 6 was released
   last month)

9. Pushing the app on
   the App Store from
   the command line
   • ¯\(ϑ)/¯
   • Unofficial API
   • Reverse engineered by looking at
   Application Loader ?

10. Writing a script to wrap all this
    • Usually end-up copy/pasted accross multiple projects...
    • ...or shared as a submodules or something similar
    • Suggested a relatively simple one in my book, around
    100LOC (#humblebrag)

18. Wrapping the Fastlane tools using
    Fastlane
    gem install fastlane
    fastlane init
    (Even better is adding Fastlane as a dependency in your
    Gemfile)
    source "https://rubygems.org"
    gem 'fastlane', '~> 1.36', '>= 1.36.4'%

    platform :ios do
    before_all do
    carthage(platform: "iOS")
    end
    desc "Submit a new Beta Build to Apple TestFlight"
    lane :beta do
    # ...
    end
    end
