经过几年的发展,Swift已经成为iOS开发语言的“中流砥柱”,Swift提供了非常灵活的高级别特性,例如协议、闭包、泛型等,并且Swift还进一步开发了强大的SIL(Swift Intermediate Language)用于对编译器进行优化,使得Swift相比Objective-C运行更快性能更优,Swift内部如何实现性能的优化,我们本文就进行一下解读,希望能对大家有所...
Therefore, when examining Swift vs. Objective-C, the use of ARC in Swift gives it a noticeable edge, especially for developers seeking to optimize their app development process for efficiency and performance.3. Interoperability with Objective-C...

Performance Swift 具有一门高效语言所需要具备的绝大部分特点。与 Ruby 或者 Python 这样的解释型语言不需要再做什么对比了,相较于其前辈的 Objective-C,Swift 在编译期间就完成了方法的绑定,因此方法调用上不再是类似于 Smalltalk 的消息发送,而是直接获取方法地址并进行调用。虽然 Objective-C 对运行时查找方法的过...
