Is SearchViewController actually referenced in your code somewhere? You need something in the binary which would cause the class to get loaded in the first place or it will not be linked into the binary and not found by IB. This has been an issue with IB and objC forever, I don’t see why Swift would be any different.
I have dummy bits of code in a few of my apps which do nothing but get the class of objects in IB which aren’t in the code elsewhere, that is enough to keep the class in the image.
