Objective-C Metaprogramming

Getting the list of classes

Used to be that you’d use objc_getClassList, but that’s now deprecated in favor of objc_copyClassList. However, you can’t easily enumerate over that returned array in swift, so use the following code:

var count: UInt32 = 0
let classList = objc_copyClassList(&count)!
defer { free(UnsafeMutableRawPointer(classList)) }
let classes = UnsafeBufferPointer(start: classList, count: Int(count))
for cls in classes {
    print(String(cString: class_getName(cls)))
