Swift code getting <Error>: CGAffineTransformInvert: singular matrix

[dosapati]

While using Swift code If any card is clicked by choosing the buttons instead of Pan gesture - the animation is not showing up.

In Xcode console we see this error.

SwiftLikedOrNope[3704] <Error>: CGAffineTransformInvert: singular matrix

Tried to fix this by initializing originalTransform in UIView+MDCSwipeToChoose.m

self.mdc_viewState.originalTransform = CGAffineTransformMake(1, 0, 0, 1, 0, 0);

Donno is this the right way or not, comment or suggest a better solution. If our approach is right, let me know if you want me to make a pull request and check in the code.

Thanks @dosapati Fixed it for me too.

Since originalTransform is CATransform3D :

self.mdc_viewState.originalTransform = CATransform3DMakeAffineTransform(CGAffineTransformMake(1, 0, 0, 1, 0, 0));
