Changes in this fork

Compiling

Updated to Swift 5
Updated for compatibility with iOS 13

Cropping

Image cropping now uses a rectangle with a specified aspect ratio rather than a square.
Added a center point circle in the middle of the crop rectangle that shows a touch point for moving the crop overlay. Previously, the user could move the crop overlay by dragging anywhere in the crop bounds, but this prevents pinch-resizing of the image except at the very edge. The resize corners still work as before.

Camera

Cleaned up the constraints for the flash, swap, and library buttons to work properly in both landscape orientations
Update the overlay constraints when rotating, so the overlay is properly positioned and sized
If the camera is not available (ie. on simulator), pop up an error rather than crashing
Hide flash button if the flash is not available (for instance, iPads)

Library Picker

Adding a pinch gesture to increase or decrease the number of columns shown, up to a min or max value

Confirm / Cropping View

Significant updates to the presentation of the image, scrolling, and cropping to fix inconsistencies especially when switching between portrait and landscape. See source file for full details.
Allow zooming in on the image during cropping
Rotate button to rotate the image 90 degrees clockwise on each press

Example

Added a tap gesture on the displayed image to allow re-cropping the image (illustrates bringing up the crop view directly)
The example was updated to show a crop aspect ratio of 1.2
