IBOutlets are nil on iOS 8 devices, but work fine on iOS 9 (Swift)

Question

When running iOS 8, the IBOutlets of my nib based view controllers are nil, but when running iOS 9, they work fine. Any ideas why this might be happening?

My app supports iOS 8+, and I'm running Xcode 7.2.

Answer 1

The problem was in the way my UIViewController was instantiated. Changing let myVC = MyViewController()

for let myVC = MyViewController(nibName: "MyViewController", bundle: nil) fixed the problem.
