Enhances core foundation framework with extensions for converting standard types to Core Foundation types, creating data structures, and managing memory with automatic release capabilities.
This is a Kotlin MultiPlatform library that provides extensions for core foundation framework on MacOS.

Convert kotlin types to cf types. Each of these calls transfers ownership of the values to the caller.
val cfByte = 1.toByte().toCFNumber()
val cfShort = 2.toShort().toCFNumber()
val cfInt = 3.toCFNumber()
val cfLong = 4L.toCFNumber()
val cfFloat = 5f.toCFNumber()
val cfDouble = 6.7.toCFNumber()
val cfString = "string".toCFString()
val cfBoolean = true.toCFBoolean()
val cfDictionary = mapOf<COpaquePointer?, COpaquePointer?>().toCFDictionary()
val cfMutableDictionary = mutableMapOf<COpaquePointer?, COpaquePointer?>().toCFMutableDictionary()
val cfArray = listOf<COpaquePointer?>().toCFArray()
val cfMutableArray = mutableListOf<COpaquePointer?>().toCFMutableArray()
val cfSet = setOf<COpaquePointer?>().toCFSet()
val cfMutableSet = mutableSetOf<COpaquePointer?>().toCFMutableSet()
val cfData = listOf(1.toUbyte()).toCFData()
val cfMutableData = mutableListOf(1.toUbyte()).toCFMutableData()
val cfRange = (0 .. 10).toCFRange()
Create CF data structures.
val cfDictionary = cfDictionaryOf()
val cfMutableDictionary = cfMutableDictionaryOf() // or CFMutableDictionary()
val cfArray = cfArrayOf()
cfMutableArray = cfMutableArrayOf()
cfSet = cfSetOf()
cfMutableSet = cfMutableSetOf()
cfBag = cfBagOf()
cfMutableBag = cfMutableBagOf()
cfData = cfDataOf()
cfMutableData = cfMutableDataOf()
cfBinaryHeap = cfBinaryHeapOf(kCFStringBinaryHeapCallBacks)
cfBitVector = cfBitVectorOf()
cfMutableBitVector = cfMutableBitVectorOf()
cfDate = CFDate()
When reading data from the above data structures there are helpers to work with the correct type.
val key = "string2".toCFString()
val cfDictionary = cfDictionaryOf(key to "string2".toCFString())
// by default, it's just a non-specific pointer type
val pointer: COpaquePointer? = cfDictionary[key]
// this reinterprets the pointer as a CFStringRef and checks if it's the actual correct type
val string2: CFStringRef = pointer.asCFString()
A helper lambda can be used to automatically release the allocated values so you don't need to CFRelease().
import nl.ncaj.cf.extension.CFMemScope.Companion.cfMemScoped
fun func() = cfMemScoped {
val arr = cfMutableArray()
// ...
// no need to call CFRelease() here, it's automatically released
}
