Unable to bridge NSNumber to Float

[turk-jk]

I have know idea what I'm doing wrong but it's crashing since swift 4.1
` }

    let frameDelays: [Float] = frameProperties.map() {
        var delayObject: AnyObject = unsafeBitCast(CFDictionaryGetValue($0, Unmanaged.passUnretained(kCGImagePropertyGIFUnclampedDelayTime).toOpaque()), to: AnyObject.self)
        if (delayObject.floatValue == 0.0){
            delayObject = unsafeBitCast(CFDictionaryGetValue($0, Unmanaged.passUnretained(kCGImagePropertyGIFDelayTime).toOpaque()), to: AnyObject.self)
        }
        return delayObject as! Float   // <-- error occurs here
    }
    return frameDelays
}`

Same issue for me too
For now i hard coded it .
if let probability = delayObject as? Float{
return probability
}
return 0.1

I suggest this
if let n = delayObject as? NSNumber { return n.floatValue }

I fixed this with
return delayObject.floatValue as Float

ie. get the scalar float value out of the NSNumber object before trying to bridge. It should always succeed.
