Problem with CoreMotion causes UI API called on a background thread, IPhone X series

[hackerpex]

this problem just block presentation on ios 12x only int IPhone X series

this part of code was commented and solve the problem

// let motionEffectsX = UIInterpolatingMotionEffect(keyPath: "center.x", type: .tiltAlongHorizontalAxis)
// motionEffectsX.maximumRelativeValue = offset
// motionEffectsX.minimumRelativeValue = -offset
//
// let motionEffectsY = UIInterpolatingMotionEffect(keyPath: "center.y", type: .tiltAlongVerticalAxis)
// motionEffectsY.maximumRelativeValue = offset
// motionEffectsY.minimumRelativeValue = -offset

// let group = UIMotionEffectGroup()
// group.motionEffects = [motionEffectsX, motionEffectsY]
//
// addMotionEffect(group)

thanks a lot

Wrapping that piece of code with a dispatch async also solves the problem

DispatchQueue.main.async {
     let motionEffectsX = UIInterpolatingMotionEffect(keyPath: "center.x", type: .tiltAlongHorizontalAxis)
     motionEffectsX.maximumRelativeValue = offset
     motionEffectsX.minimumRelativeValue = -offset
            
     let motionEffectsY = UIInterpolatingMotionEffect(keyPath: "center.y", type: .tiltAlongVerticalAxis)
     motionEffectsY.maximumRelativeValue = offset
     motionEffectsY.minimumRelativeValue = -offset
            
     let group = UIMotionEffectGroup()
     group.motionEffects = [motionEffectsX, motionEffectsY]
            
     self.addMotionEffect(group)
}

I'm running 5.2.1 and still get this error. Is it not merged?

Updated my project to Xcode 10.2, Swift 5, cloned your repo and updated PKHUD to 5.2.2, and same Main Thread Checker error. This is on iPhone XR, btw.
