[Swift-user] readData is treating line as a single field

[Ketan Maheshwari]

Hi Mike,

I am not sure how to introduce a field separator to readData(). I tried
adding '|' between header and data fields but seems readData is complaining
that file header does not match type and it expected space separated items:

File header does not match type. Expected 4 whitespace separated items. Got
5 instead.
swiftscript:readData, quadui-multi.swift, line 27
