iink SDK on Device

Sample app crashes on iOS13

Dear Myscript Team,

When running the "GetStarted" sample application (https://github.com/MyScript/interactive-ink-examples-ios/tree/master/Examples/GetStarted)
on iOS13.3, touching the converted text causes the application to crash.

The error log is shown below,
