Dequeuing cells in Swift #12

Open hartbit opened 7 years ago

hartbit commented 7 years ago

In Swift, when de-queuing custom cells who's class has been swizzled causes a crash:

Could not cast value of type 'MyApp.SectionHeaderView' (0x10e9afee0) to 'MyApp.SectionHeaderView' (0x123532bb8).

Intersesting.. Any chance you would be able to put together a small example project and I’ll take a look.

I’ll try this evening.

Cheers, I have an idea what it is but not quite what to do about it. Swizzled instance has different “isa"

hartbit commented 7 years ago

Yeah, was thinking the same, and it doesn't work with a Swift runtime cast.

johnno1962 commented 7 years ago

I found I could only replicate this when the cell class was in the same file as the UITableViewController subclass. Could this be the solution?

hartbit commented 7 years ago

I'm in that case!
