Swift Type Extensions

This page contains links to blogposts that contain extensions for predefined Swift types.

String extensions

This extension introduces an operation to rebase a String.Index if the originating string of an index variable has changed. This is important when changing a string's length because the indexes before the string update are still using the older string endIndex.

These two extensions check if a UTF16 character at the given String.Index is present in the NSCharacterSet lowercase resp uppercase.

Only available for mutable strings, this extension replaces a character in the string with a given character.

Only available for mutable strings, this extension works only on lowercase or uppercase characters and reverses it case.

Array extensions

This extension reintroduces the removeObject operation (from the NSArray) to the Swift array type.

UInt8 extensions

Bit access for a the UInt8
Accessing the bits as a set of 8 Bools in a tuple.

OptionSetType extensions

Factory method
