Transcript

1. 10 LESSONS WE CAN LEARN FROM THE 30,886 (AND COUNTING) SWIFT COMMITS (AND IT'S NOT A CLICKBAIT)
2. 10 LESSONS WE CAN LEARN FROM THE 30,886 (AND COUNTING) SWIFT COMMITS (OK, IT'S A CLICKBAIT)
3. 1. EVERYTHING HAS A BEGINNING
6. Makefile lib/Lex/Lexer.cpp lib/Lex/Makefile lib/Makefile lib/Parse/Makefile lib/Parse/Parser.cpp tools/Makefile tools/swift/Makefile tools/swift/swift.cpp
7. swift.cpp int main() { }
8. 11 COMMITS AFTER
9. 386 COMMITS AFTER
11. 2. SVN IS NOT DEAD YET (AT LEAST NOT TO EVERYBODY)
15. 3. IF YOU STRUGGLE WITH git YOU'RE NOT ALONE
24. 4. 36% OF SWIFT IS WRITTEN IN SWIFT
26. 5. ♥ IS IN THE STDLIB
27. SOME EXAMPLES > Optionals > VarArgs > Int > Bool > Bit
29. 6. I TAWT I TAW A PYTHON
32. 7. GENERATE YOUR BOILERPLATE
33. Template %{ integerBinaryOps = [ (x[:-1], x[-1], x[:-1].capitalize(), 'a result') for x in 'add+ subtract- multiply* divide/'.split() ] + [ ('remainder', '%', 'Divide', 'the remainder') ] }% Usage public protocol _IntegerArithmeticType { % for name,_,Action,result in integerBinaryOps: /// ${Action} `lhs` and `rhs`, returning ${result} and a `Bool` that is /// true iff the operation caused an arithmetic overflow. static func ${name}WithOverflow(lhs: Self, _ rhs: Self) -> (Self, overflow: Bool) % end }
34. 8. COMMENT YOUR COMPLEXITY
35. /// Insert `newElement` at index `i`. /// /// Invalidates all indices with respect to `self`. /// /// - Complexity: O(`self.count`). public mutating func insert(newElement: Character, atIndex i: Index) { withMutableCharacters { (inout v: CharacterView) in v.insert(newElement, atIndex: i) } }
36. 9. WE ALL CODE BY NIGHT
38. 10. IT'S EASY TO COMPLAIN ABOUT SOMEONE ELSE'S CODE
41. THANKS!
