Check if Localizable.strings file is valid
Use plutil from the Terminal:
plutil -lint Localizable.strings
In addition to @Aderstedt's answer:
plutil -lint Localizable.strings does work, but you have to run it for each version of the file. E.g
cdinto your project rootcd en.lproj- you can replace this with any localisation you are working with.plutil -lint Localizable.strings
When you run step 3, you will either be shown an error, telling you what is wrong with your file. Or you will be told the file is OK
As mentioned above plutil (property list utility) is a great tool to validate your .plist and .strings files if you edit them manually. You can apply it to all your .strings file by combining it with find. In your project directory run
find . -name *.strings -exec plutil -lint {} \;or use
find . -path ./DerivedData -prune -o -name *.strings -exec plutil -lint {} \;if you like to exclude your DerivedData directory (as I usually do).
