The last 128054 is the hexadecimal number 1f436. is exactly the Unicode scalar u+1f436 of the dog's expression character.There is also a second way to get the value property of Unicodescalar, which is to use this character to create a new string value, such as a string fill:For scalar in Dogstring.unicodescalars { println ("

is not interesting. See "Objective-c BASIC Programming" preliminary to OBJC have a preliminary understanding, (more than C + +, but more than C, but more than a lot of control, in fact there is a lot of difficulty).But Swift is an easy-to-use language, borrowed in the library of Pitre's "Swift Basic Tutorial 2nd", a cursory turn, the language can be very si

with the wisdom of Appleproject culture.His compilers are specifically designed for performance optimization, and programming languages are optimized for development, without compromising on each other.He was designed to extend from Hello, world to the entire operating system. All of this makes swift a solid future investment for developers and Apple.Swift is a fantastic way to write iOS and OS X apps, and it continues to add new features and functio

Swift development-Storyboard usage tutorial, swift-storyboard If the App contains many different pages, using Storyboard can help you reduce the code for redirecting between pages. In the past, developers created interface design files ("nib" or "xib" files) for each View Controller. Now, only one Storyboard can capture the interface design of all view controller

in Apple software development (by Gashero).OBJECTIVE-C developers will feel Swift's déjà vu. Swift uses objective-c named parameters and a dynamic object model. Provides interoperability with the cocoa framework and the mix-and-match. Based on these fundamentals, Swift introduces a number of new features and a combination of process-oriented and object-oriented features.Swift is also friendly to the new pr
