Open Radar

 
Summary:
UIAlertView implicitly calls through to initializers which, if not overridden in a Swift subclass, results in a fatal error. These implicit requirements are different in both iOS 7 and 8, and in neither case do the tools tell you the implementations are expected.

Steps to Reproduce:
1) Download or clone https://github.com/drance/radars/tree/SwiftAlertDeath
2) Run the project on iOS 7 or 8. Tapping the "Show Alert" button should work fine.
3) Comment out the first override init() method, then repeat step 2 on iOS 7.
4) Comment out the second override init(frame:) method, then repeat step 2 on iOS 8.


Expected Results:
Expect no crashes, or at least a build warning that the override implementation is required.


Actual Results:
Crashes in different ways on both iOS 7 and iOS 8. Here are the respective error messages prior to crashing, for reference:

(iOS 8)
BHSAlertView.swift: 11: 7: fatal error: use of unimplemented initializer 'init(frame:)' for class 'SwiftAlertDeath.BHSAlertView'

(iOS 7)
BHSAlertView.swift: 11: 7: fatal error: use of unimplemented initializer 'init()' for class 'SwiftAlertDeath.BHSAlertView'
