Crash in Swift 3

[Chelsea-Pritchard]

I updated to Swift 3 and now I'm getting a crash every time I call "showOverlayAddedto" MRProgressOverlayView.showOverlayAdded(to: self.view, title: "Connecting...", mode: .indeterminate, animated: true)

See error below:

This is the line causing the crash in the MRProgressOverlayView.m class:

I'm getting the same crash from Objective-C. Did you find a way to fix this @Chelsea-Pritchard ?

[Chelsea-Pritchard]

@lukaskollmer My fix was to remove MRProgress and replace it with SwiftSpinner :)
