UIGraphicsGetCurrentContext() returns nil -what now?

I'm writing an iOS application and integrated FDWaveformView 2.0.0 via CocoaPods. Sometimes UIGraphicsGetCurrentContext() returns nil and I get the "FDWaveformView failed to get graphics context" log message. 

   guard let context = UIGraphicsGetCurrentContext() else {
        NSLog("FDWaveformView failed to get graphics context")
        return
    }

Does anyone know how to solve this issue?

Ensure that You are calling UIGraphicsGetCurrentContext() inside draw(_ rect : CGRect)() method.

Also ensure that you are not manually calling draw(_ rect : CGRect). Instead call setNeedsDisplay() which will call draw(_ rect : CGRect).
