Apple SDK and Swift UI

Swift language

• — Modern language style
  • — Strong typed but type inferred
• — camel Case
• — File names start with uppercase letters
• — New features
  • — optinoal, if-let and guard-let
  • — defer
  • — Procotols
  • — Delegates
  • — Closures
    • — To get a closure from named function,
      • — remove func keyword and function name
      • — move the opening brace to the beginning
      • — after tye types, put an in keyword
    • — Can remove names and use $0, $1, etc.
    • — Can remove return
    • — Trailing closure
      • — If a closure is the final argument of a function, that can stand outside the parantheses
  • — Structures
  • — Properties
  • — argument labels in function
  • — Tuples have lables
  • — weak reference
    • — the memory management counter doesn't count this reference
    • — this way the original variable can be removed from memory even if this particule referring object exists
