CoreFoundation is a cross-platform C-based API that provides reference-counted data structures, IPC facilities, run loops, etc. A subset of it is open-sourced as "CF-Lite".
This framework also provides some crucial Objective-C classes such as NSObject, NSString, NSArray, etc.
For one example of using CoreFoundation version numbers, see Updating extensions for iOS 7#Detecting iOS 7.

Parameters for CoreFoundation applications
CoreFoundation recognizes the following special command-line arguments:
| Flag | Purpose |
|---|---|
| -AppleLanguages "(lang1, lang2, ...)" | Set the list of languages for localization. |
Environment variables
Application built with CoreFoundation will recognize the following environment variables
| Name | Default | Purpose |
|---|---|---|
| __CF_USER_TEXT_ENCODING[1] | 0x1f5:0:0 (mobile) or 0x0:0:0 (root) | Override the default text encoding. |
| CFFIXED_USER_HOME | NULL | The home directory recognized by CoreFoundation. (Note that the system environment variable HOME is also in use.) |
| CFPREFERENCES_LOG_EQUAL_VALUES | false | Displays a debug-level log when trying to set an unmodified value in preferences (NSUserDefaults). |
| CFBundleDisableStringsSharing | false | Do not share *.strings files. (?) |
| IPHONE_SIMULATOR_DEVICE | iPhone | Used by the internal _CFGetProductName to get the current platform. This environment variable will be checked only when sysctl hw.machine returns a value other than iPhone, iPod or iPad (what about AppleTV?). |
| CFPropertyListAllowImmutableCollections | false | Force collections (array, dictionary) parsed from property lists to be immutable. |
| CFUUIDVersionNumber[2] | 4 | UUID version to use. Only supports 1 or 4. |
| __CF_DEBUG_EXPANDED_SET CFCharacterSetCheckForExpandedSet |
false | Enable check for expanded character sets. When an expanded set is detected, a warning "An expanded CFMutableCharacter has been detected. Recommend to compact with CFCharacterSetCreateCopy" will be printed. |
| OAKeepAllocationStatistics[3] | false | ? |
| NSObjCMessageLoggingEnabled[4] | no | - |
| NSZombieEnabled[5][6] | no | Use "zombies" for easier detection on misusing deallocated objects. |
| NSDeallocateZombies[5] | no | |
| CFZombieLevel[7] | 0 | |
| CFStringDisableROM | false | ? |
| CFLOG_FORCE_STDERR | false | Stream error from CFLog to stderr too. |
| CFNETWORK_LIBRARY_PATH | /System/Library/Frameworks/CFNetwork.framework/CFNetwork | Manually set the path of the CFNetwork binary. |
| NSAutoreleaseHaltOnFreedObject | no | Kill the process immediately when calling -autorelease on a freed object. |
| NSAutoreleaseHaltOnNoPool | no | Kill the process immediately when calling -autorelease without a pool. |
| CFBundleUseDYLD | ? | Use low-level dyld(3) functions instead of dlopen(3)/etc. to check if a bundle is loaded or not. |
| CFProcessPath | - | Manually set the process path. |
| USER HOME PATH DYLD_IMAGE_SUFFIX TZFILE TZ |
- | Various CF functions depend on these info. |
