The IBM Worklight team has been testing Worklight with Apple's iOS 8.0 operating system and the good news is that Worklight now supports running existing and new applications on iOS 8.0.
Testing has been
performed on Worklight 5.0.6x, 6.0x, 6.1x, and 6.2x.
Obviously in some cases,
depending on the functionality being used, a Worklight iFix may be
required to address known issues. Plans are to have this iFix available
concurrent with iOS 8.0 availability.
