IBAction inside UITableViewCell not called in iOS 9

I have a custom

subclass which contains a few
methods wired up from a nib.

Under iOS 8 everything works as expected. If the user taps one of the buttons, the appropriate
is called. If the user taps anywhere else on the cell, the
UITableView didSelectRowAtIndexPath
is called.

Under iOS 9, my IBAction methods are never called. The
is always fired regardless of where the user taps in the cell (button or not).

The project is compiled under Xcode 6 / Swift 1.2.

I found this post on an Apple forum w/ no solution. They seem to have the same issue.

I figured out the solution, hopefully this answer will save someone else the time.

I inherited this code base and it had some issues. The UITableViewCell's that were not working under iOS 9 were not using UITableViewCell nibs w/ a ContentView. Instead, someone had created a UIView nib and then pointed it to a custom UITableViewCell subclass. The nibs did not have a ContentView and apparently iOS 9 is a little more picky about that. This implementation worked fine under iOS 8 and there were no compiler or runtime errors or warnings.

The solution was to create a new UITableViewCell subclass and let Xcode auto create the nib for it. Then I copied over all of the UI and code from the old nib and pasted it into the ContentView of the new nib. I then had to fix up the constraints and rewire the connections to the custom subclass.
