nesterenkodm / chrtextfieldformatter Goto Github PK

I use swift and use cardNumberFormatter.maskedStringFromString(text)，but it crash on "NSUInteger cursorPositionInSpacelessString = *cursorPosition;" , the code in CHRCardNumberMask.m file line 49.
What should I do? Forgive my English is very poor.

Skipped building CHRTextFieldFormatter due to the error:
Dependency "CHRTextFieldFormatter" has no shared framework schemes for any of the platforms: iOS

I tried to paste some strings like "000000000" 、"111111111",the course didn't at the end
