@mjtsai I think that’s directly analogous to ObjC—initializers that return nil are always improved by adding an …error: argument.

@optshiftk Right, but in Objective-C that doesn’t really affect the callsite.

@mjtsai Adding an …error: argument does affect the callsite. -
@optshiftk The caller can just pass NULL if it doesn’t care. Nothing else changes. With Swift, the caller has to add do-catch blocks. - View other replies

@mjtsai Or the caller can prefix with `try!`. Either way, it’s a forced change at the callsite. -
@optshiftk “try!” doesn’t mean “I don’t care about the error details.” It means “I know this will succeed, so crash if it doesn’t.”
