Why is the Date constructor deprecated, and what do I use instead?

The java.util.Date class isn’t actually deprecated, just that constructor, along with a couple other constructors/methods are deprecated.

First of all, in glibc, malloc is defined as a weak symbol, which means that it can be overwritten by the application or a shared library. Hence, LD_PRELOAD is not necessarily needed.

Replacement for stringByAddingPercentEscapesUsingEncoding in ios9?

The deprecation message says (emphasis mine): Use stringByAddingPercentEncodingWithAllowedCharacters(_:) instead, which always uses the recommended UTF-8 encoding, and which encodes for a specific URL component or subcomponent since each URL component or subcomponent has different rules for what characters are valid. So you only need to supply an adequate NSCharacterSet as argument. Luckily, for URLs there’s … Read more
