9. Swift Playground @chiarachiappini
10. Swift and Objective-C Swift let name ="Chiara" print("Hello \(name)") Objective-C NSString*str =@"Hello Chiara"; NSLog(@"%@", str) @chiarachiappini
11. Xcode vs Appcode @chiarachiappini
12. Dependency management Cocoapods vs Maven vs Gradle @chiarachiappini
13. sudo gem install cocoapods pod init edit PodFile (similar to editing pom.xml) pod install @chiarachiappini
14. platform :ios, '8.0' use_frameworks! target 'SwiftTalk' do pod 'Alamofire', '~> 3.1' end target 'SwiftTalkTests' do pod 'Quick', '~> 0.6.0' pod 'Nimble', '2.0.0-rc.3' end
15. Protocol vs Interface @chiarachiappini
16. protocol Sweet { var sugarQuantity: Int { get } } class BlackChocolate: Sweet { var sugarQuantity: Int = 10 } @chiarachiappini
17. Unit Tests @chiarachiappini
18. XCTest vs JUnit testing framework integrated with XCode @chiarachiappini
19. XCTest example class MyTestsXCTests: XCTestCase{ let myNumbers = [1,2,3] func testNumbersWithXCTest() { XCTAssertEqual(1 + 1, 2, "expected one plus one to equal two") for number in myNumbers{ XCTAssertLessThan(number, 4) } } } @chiarachiappini
20. Use @testable import XCTest @testable import CodemotionExamples class CodemotionExamplesTests: XCTestCase { func testBlackChocolateHasSugar() { let blackChocolate = BlackChocolate() XCTAssertEqual(blackChocolate.sugarQuantity, 10, "Expected sugar quantity is 10") } } @chiarachiappini
21. Quick and Nimble Quick:behaviour driven testing framework Nimble: fluent assertions https://github.com/Quick/Nimble @chiarachiappini
22. Nimble func testNumbersWithNimble() { expect(1+1).to(equal(2)) expect([1,2,3]).to(allPass(beLessThan(4))) } @chiarachiappini
23. func testStringWithNimble() { let myString = "Hello!" expect(myString).to(equal("Hello!")) expect(myString)==("Hello!") expect(myString).to(beginWith("Hel")) } @chiarachiappini
24. Quick class MyTestsQuick: QuickSpec { override func spec() { describe("Testing numbers") { context("when adding 1 and 2"){ it("results as 3") { expect(1+2).to(equal(3)) } } } @chiarachiappini
25. Testing and CI @chiarachiappini
26. Continuous Integration early feedback @chiarachiappini
27. Continuous Integration early feedback team peace of mind and alerting @chiarachiappini
28. Continuous Integration early feedback team peace of mind and alerting standardized build @chiarachiappini
29. Continuous Integration early feedback team peace of mind and alerting standardized build record of results @chiarachiappini
30. Continuous Integration early feedback team peace of mind and alerting standardized build record of results support release process @chiarachiappini
31. Continuous Integration early feedback team peace of mind and alerting standardized build record of results support release process first step to continuous deployment @chiarachiappini
