Randomly returns totally wrong values with Swift optimizations (-O) turned on
public func optionalMax <T: Comparable>(elements: T? ...) -> T? {
var maximumElement: T?
for element in elements {
if let element = element {
if let existingMaximumElement = maximumElement {
if element > existingMaximumElement {
maximumElement = element
}

iOS View Controller Lifecycle Validation
VIEW CONTROLLER LIFECYCLE BROKEN!
MFMailComposeInternalViewController (indirectly) called super.viewDidAppear() multiple times.
Possible causes:
- MFMailComposeInternalViewController or one of its superclasses called super.viewDidAppear() multiple times
- it was called manually (it should never be called manually)
- the controller containment implementation of MFMailComposeViewController or one if its parents is broken

UISplitViewController sucks!
(lldb) po 0x7c953600 // UISplitViewController
<UISplitViewController: 0x7c953600>
(lldb) po [0x7c953600 childViewControllers] // UISplitViewController's children
NSArray(
<UIViewController: 0x7be5a6e0>,
<UIViewController: 0x7be9b130>
)
(lldb) po [0x7be5a6e0 parentViewController] // master child's parent
