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.

Swift closure loop reference and swift loop reference When a closure is used, the class itself holds self, and then accesses the attributes of self or self in the closure, which will lead to nausea of circular reference. The solution provided by swift is to define the capture list in the closure, and the capture list is how the closure wants to reference the cap

First of all, SWIFT is very popular. It ranks 16 in the month when it comes out. Why is it so hot? Is it because of the Apple brand? Or other reasons? As a code farmer (working for more than 15 years), I will talk about my personal opinions. There are many excellent PC-side development languages: JavaScript, Python, and Ruby. On the Mobile End, Java for Android is slow, and there is no freshness in addition. In iOS, objective-C is not slow, but the sy

An operator (operator) is a special symbol or phrase used to examine, change, or combine values. For example, the plus operator has two numbers added (such as let i = 1 + 2), and some more complex operators, such as logic and Operators () (e.g. if Entereddoorcode Passedretinascan) And the self-increasing operator (++i) (a convenient notation for the value of I plus 1). Swift supports most of the operators of standard C languages, and has improved so
