Objective-C still has both ARC and exceptions. Although the documentation [1]
says that ARC is not exception safe by default, but it does have a flag to
enable it "-fobjc-arc-exceptions".
[1] http://clang.llvm.org/docs/AutomaticReferenceCounting.html#exceptions
From your reference:
"Making code exceptions-safe by default would impose severe runtime and code
size penalties on code that typically does not actually care about exceptions
safety. Therefore, ARC-generated code leaks by default on exceptions, which is
just fine if the process is going to be immediately terminated anyway. Programs
which do care about recovering from exceptions should enable the option."
Note "severe runtime and code size penalties". Just what I said.
