To create an iOS app that uses LispWorks, you need a license for LispWorks for iOS Runtime.
This section describes issues relevant to delivery of the LispWorks component of an iOS app.
You will need an Xcode project which includes any GUI part and links with a iOS object file (a
.o file) created with LispWorks. You create this LispWorks runtime with a special LispWorks image which runs in the QEMU emulator on Mac OS X, calling the function deliver. You can also build a runtime for the iOS Simulator running on Mac OS X.
