Apple is still pretty innovative, but it hasn't been as visible as a new product for a while. They already shrunk computers down to the size of a watch, it's not obvious what more they can do, and the technology is probably not ready for wearables, etc.

Some innovations I can think of are force touch, fingerprint sensor (arguably), Face ID, T2 chip / hardware security, Touch Bar, the heart sensor on Watch, and (possibly) wireless charging. Now, some of those, like the Touch Bar are widely reviled here, but whether or not you find it useful, it is an innovation.

Design-wise there's been incremental innovations, some of which haven't succeed (scissors keyboard). The Jet Black iPhone was a design innovation, or at least a manufacturing innovation, since they had to preprocess the metal surface so that the black dye would soak in beyond the outer layer.
