You have a lot of responsibilities and plenty of to-dos to keep track of. Add in your email and Instapaper and it can feel impossible to make any progress. But it's not! In this talk we’ll discuss basic principles you can use to organize yourself, stay atop your responsibilities, and destress at the same time. We’ll also cover some common organizational pitfalls that we as programmers can fall into, and we’ll briefly discuss tooling, including the pros and cons of using a tool like OmniFocus.

• throws in Swift 2 is just another way to return from a function/method. Because of its propagation semantics, it's not really "exceptions", which is probably a good change.
• But unlike an Either or Result return type, throws in Swift 2 cannot communicate type information.
• This sucks; and we will realize it sucks when we keep having to refer to documentation every time we call a function that throws to see what sort of errors we may have to handle. This is part of the problem that types solve; they are documentation, with compiler-enforced guarantees.
• Arguments based on the clunkiness of pattern-matching on a Result type vs. the new syntax are not valid. Had the Swift team chosen to introduce a blessed stdlib Result type, they could have introduced elegant syntax to handle it without requiring boilerplate; remember, everything related to throws is new syntax.
• Yes, this would make versioning harder. Changing the types of errors you return changes the contract of an API, if you care abou
