I've got a splitview with 3 columns, and I can adjust the position of one of the columns, but not the other one. I've no idea what I might have done to prevent this. I've tried changing the alignment things and deleting the constraints.
I can delete the entire view and start again, but obviously I'd prefer not to.
When the app is built, I can adjust the split to the correct size, so there's nothing preventing that. I can move the subviews themselves, or drag the entire view off, but the column just won't move.
Probably something really basic, but it's driving me potty.
