Got the following weird, overflow-looking error:


I then cleared it and just entered the first line. CRASH!

I then restarted and enterested just the first line. CRASH!

I then restarted and all was well for both the first line and the whole content. Probably not replicable.

Start at the import-SSKR page in the Swift iOS app and try the supplied eight-line SSKR, then the first line alone, after restarting and clearing the input. Compare the overflow-looking error and intermittent crash with a successful import; done means the supplied inputs no longer produce an overflow error or crash.
