iOS Support

Bringing Java to iOS follows a staged approach. First we validate the runtime with a minimal example, then we provide two independent tracks for developers: generating Java libraries for use in iOS projects, or building full JavaFX applications.

This is shown in the following image.

classes[JDK Classes] --> OpenJDK
OpenJDK --> helloworld[HelloWorld.jar
on iOS]
helloworld --> javalib[Native java libs
in iOS apps]
helloworld --> javaapp[JavaFX apps]

Tracks

• HelloWorld on iOS – Validate the VM and class libraries with a minimal program.
• Java Libraries for iOS – Expose Java methods to be callable from Objective-C/Swift.
• JavaFX Applications on iOS – Build full JavaFX apps for iOS.
