I'm trying to adapt the height of the cells of a UITableView in swift programmatically for iOS 7.1.2 (sadly got asked for it.). There are no issues for all iOS versions after 7 but as it is the UITableView displays with a height of 1..
Here is my code (I made the interface programmatically as I literally HATE the design interface of Xcode and don't use AutoLayout). Any ideas?
