Simple IntroductionThis article documents some of the basics of using Swift to manipulate coredata in IOS, because the lack of documentation is essentially the result of self-experimentation. Mistakes are unavoidable, please understand.Part of the content borrowed from Tim Roadley's "Learning.Core.Data.for.iOS (2013.11)", this book mainly introduces OBJC CoreData.Create a new XCode project Create a

) represent the characters d o G and! , their UTF-16 code units and UTF-8 are identical.The five and Sixth code unit values (55357 and 56374) are UTF-16 representations of the dog face character. The first value is u+d83d (decimal value is 55357) and the second value is u+dc36 (decimal value is 56374).Unicode scalarYou can access its Unicode scalar representation by traversing the Unicodescalars property of the string. It is an attribute of type Unicodescalarview, and Unicodescalarview is a coll
