Strings:

_NSCFString - a CFStringRef or CFMutableStringRef. This is the most common type of string object currently.
    - May have 8 bit (ASCII) or 16 bit (UTF-16) backing store
_NSCFConstantString - a compile time constant CFStringRef, like you'd get with @"foo"
    - May also be generated by dynamic string creation if matches a string in a pre-baked table of common strings called the StringROM
NSBigMutableString - an NSString backed by a CFStorage (https://github.com/opensource-apple/CF/blob/master/CFStorage.h) for faster handling of very large strings
NSCheapMutableString - a very limited NSMutableString that allows for zero-copy initialization. Used in NSFileManager for temporarily wrapping stack buffers.

Cycript on Mojave

Cycript is a tool I find very helpful. It's an effective REPL for Objective-C. When I updated to macOS Mojave, I found that cycript no longer worked because it was linked against an old version of Ruby. After attempting to compile from source, I tried another solution. install_name_tool is an open source tool for modifying the names of linked shared libraries in a Mach-O.

Solution

$ install_name_tool -change /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/libruby.2.0.0.dylib /System/Library/Frameworks/Ruby.framework/Versions/Current/usr/lib/libruby.dylib Cycript.lib/cycript-apl
$ install_name_tool -change /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/libruby.2.0.0.dylib /System/Library/Frameworks/Ruby.framework/Versions/Current/usr/lib/libruby.dylib Cycript.lib/libcycript.dylib

# Set the target disk as a variable

echo "Target disk is \"$TARGET\""
