I was working with xliff file without any issues translating one of my apps to spanish. Now all of sudden Xcode's "Export for Localization" feature has stopped working. If I go to Editor->Export for Localization nothing happens, I am asked where I want to save the xliff file but when I select a location nothing happens. If I try to do the export again I get an error message saying: "There is a localization operation in progress".
I've tried restarting Xcode and my computer to no avail. Has anybody else encountered this issue?
