It's time to develop apps for iOS and Mac OS x using the easy-to-use, comprehensive swif language.While programming languages are not so easy to fade away, the development team that insists on the fading paradigm is doing so. If you are developing applications for mobile devices and you have not studied swift, then note that when Swift involves the development of applications for Macs, iphones, ipads, Apple

Simply put your Xcode mac system in the right way. So let's take a quick look at what's going on here.1.1 Download XcodeXcode is Apple's programming tool, similar to the Microsoft-produced Visual Studio, which write

This is a profile of an API or technology that is being developed, and Apple provides this information primarily to help you plan through the use of these technologies or programming interfaces with Apple products, which may change in the future, and the software mentioned in this article should be based on the final published operating system tests and final documentation, New versions of document information may be available in the future.Swift is designed to be seamlessly compatible with Coco

not care about what aspects the project could make a breakthrough after the open-source mechanism was adopted. Apple is willing to ensure that its hardware equipment can continue to run smoothly, rather than encouraging vigorous but chaotic broad innovation. Why should Apple open-source Swift? In the future, the technical labor force will have extensive open-source experience.A computer science professor once told me that, despite his preference for

Now there is the same requirement: Write a struct, and then judge whether the integer is equal. The implementation code and output are as follows: . If there is another dema

Migration provides an opportunity to re-examine existing objective-c applications, as well as the Swift code to better optimize the architecture, logic, and performance of your application. Directly, you will use the previously learned mix and match and the interoperability between the two languages for incremental migration work. The Mix-and-match feature makes it easy to choose which features and functions to use with

This section includes the following: Prepare your Objective-c code for Migration (Preparing Your objective-c Codes for Migration) Migration processes (the migration process) Problem solving tips (troubleshooting tips and Reminders) Migration provides an opportunity to revisit existing objective-c applications and to better optimize the architecture, logic, and performance of the application by replacing some of the swift code.
