Can't retrieve localized strings from Localizable.strings file
Ok, I think I know the reason for your bug. Parse had an issue with adding Localizable.strings as documented here. This was fixed in 1.8.1 version of their framework:
V1.8.1 — AUGUST 19, 2015
...
Fixed: Overwritten localizations when used via CocoaPods and integrating as static library.

So, just make sure you use the latest version of the framework and all should work :)
