Yesterday everything was fine. Could build blank templates to the device, no problem.
Today, any attempt to build anything like a blank template to the device creates more than 21 errors.
Looking like this:
"Cannot find interface declaration...
"Cannot declare variable inside @interface
"Uknown type name "UIGestureRecognizer...
And a raft of other seemingly weird things that shouldn't happen. All in .h files that should be part and parcel of building to the device.
As I say, building to a simulator has no such problems. Works fine, even with my terrible coding.
