1. Getting Groovy with iOS Development Rahul Somasunderam 8 GR Conf July 2015
2. About Me lgtm.in, swaggydoc, ihe-iti ! java, groovy, objective-c ! @rahulsom
3. Where I work • We build a Health Information Exchange Population Health Tools • Used by 130 Health Systems, 600 Hospitals, 20K physicians • We love Groovy
7. Square Brackets Square Brackets Everywhere
8. But Shirley, there's got to be documentation
10. Tools • XCode bad. AppCode good • Objective-C and Swift • Dependency Management • Build Tools • Functional Testing
11. Dependency Management
12. Ruby got there first. Deal with it!
14. • Your app needs dependencies • Dependencies can be installed with Cocoapods • Cocoapods is a ruby gem • Ruby gems can be installed with Bundler • You WANT ruby in the user space; so RBENV • There is a brew formula for RBENV • brew is installed using system ruby
15. Build Tools
16. xcodebuild xcodebuild \ -scheme Todos \ -workspace Todos.xcworkspace \ -sdk iphonesimulator \ -configuration Debug \ DSTROOT=/Users/rahul/src/Todos/build/dst \ OBJROOT=/Users/rahul/src/Todos/build/obj \ SYMROOT=/Users/rahul/src/Todos/build/sym \ SHARED_PRECOMPS_DIR=/Users/rahul/src/Todos/build/shared \ -destination 'platform=iOS Simulator,id=CAB835ED-3EE2-47B6-AD74-C06675651CEF' \ test
17. xcodebuild • Too complex commands - Unruly bash scripts • Different tools for build, upload to testflight, hockeyapp • Very little documentation, very steep learning curve • What about functional testing?
18. xctool • Written in Objective-C • Needs advanced knowledge of Objective-C • What about functional testing?
19. Nomad CLI • Written in ruby • Great support for certificates, distribution profiles • Great support for distribution using iTunesConnect • What about functional testing?
20. What we need • Flexible build system • Support for distribution • Support for functional testing • Easy to install, even if you're an enterprise software company • Easy to run
21. Gradle Xcode Plugin buildscript { repositories { maven { url "https://plugins.gradle.org/m2/" } } dependencies { classpath "gradle.plugin.org.openbakery:xcodePlugin:0.11.3" } } ! apply plugin: "org.openbakery.xcodeplugin" ! xcodebuild { workspace = 'Todos.xcworkspace' scheme = 'Todos' target = 'Todos' sdk = 'iphonesimulator' }
22. • gradle xcodetest • gradle hockeyapp • gradle deploygate • gradle appstoreUpload • gradle oclint • gradle cpd • gradle crashlytics
23. Functional Testing
24. UIAutomation using Instruments • Record and Playback • DOM Tree access • Refactoring • Managing State • Tuneup JS? Bwoken?
25. Appium • Based on Selenium • Clients for several languages including Java • Makes your app stateless
26. Groovy + Spock • Spock's expressive testing • Groovy's metaprogramming to improve access to DOM
28. Code • https://github.com/rahulsom/todos-ios/
