传统观点认为无法在Xcode里面用Java开发iOS应用，同理在Mac上也是不可能的。但是Codename One，它向传统观点发出了挑战，并向世人证明：在Geek的词典里，“不可能”和“迟早变成可能”是同义词。
Codename One 4.0 发布了，这个新版本彻底改变了Codename One的更新方式，增加了对Progressive Web Apps（PWA）的支持，大修了设备外观并更新了后端iOS构建工具。此版本的主要重点是更好地支持同行（本地）组件，稳定性，单元测试和持续集成。
更新内容：
Has Write Once Run Anywhere with no special hardware requirements and 100% code reuse
Compiles Java or Kotlin into native code for iOS, UWP (Universal Windows Platform), Android & even JavaScript
Is Open Source & Free for commercial use with an enterprise grade commercial support
Is Easy to use with 100% portable Drag & Drop GUI builder
Has Full access to underlying native OS capabilities using the native OS programming language (e.g. Objective-C) without compromising portability
