    Does not work on iOS 12 beta 1

    Hello,

    This project is really amazing. Unfortunately, it does not run well at all on iOS 12 beta 1: background is greyed out, but nothing spins.

    Good luck for that!

    Regards, Alexandre

  • Rare critical crash

    Rare critical crash

    Hello!

    I think, you should consider either using optional with "loadingView" or apply some kind of nil

    if loadingView != nil{
        loadingView.removeFromSuperview()
    }

    In very rare cases, when you pop view controller without animation, while using "RSLoadingView" on both VCs your app can crash, becauseloadingView.removeFromSuperView() is called when loadingView is already nil.

  • App crashed due to RSloading

    App crashed due to RSloading

    most of time if there is no activity indicator showing and you call hide, it cause app to crash, Some time it crashed at following method

     public func renderer(_ renderer: SCNSceneRenderer, updateAtTime time: TimeInterval) {
  //logger.logDebug("updateAtTime \(time)")
if isResized {
  prepareForResize()
  isResized = false
} else {
  effect.update(at: time)
}
     }

    specifically on following line effect.update(at: time) with EXC_BAD_ACCESS (code=1, address=0xbadd6678a819bf85)

  • UIView.bounds must be used from main thread only

    UIView.bounds must be used from main thread only

    Hi, i'have some issue using your component on Xcode 10 👍

    I have a new warning about Thread usage, in your method prepareForResize, the access of view.bounds is not forced on the mainThread

    Any idea ? Put Dispatch on the mainQueue ? (i'not quite sure about the performance)

    Best regards
