XCBUtil.PropertyListConversionError in Xcode

Question

When I try to run my project, I get this error, pointing to my localized .strings file:

read failed: The operation couldn’t be completed. (XCBUtil.PropertyListConversionError error 1.)

What can I do to fix this issue?

Answer 1

There is a formatting error inside the .string file that the error is pointing at. Localizable .strings files should contain strings in quotes (if they contain more than one word and/or special characters) and semicolons at the end of lines, like such:

string = translation;
"another string" = "another translation";

Please refer to this solution to find the error.

You should execute

/usr/bin/plutil -lint <path to .strings file>

in Terminal to find the exact issue.

Answer 5

For me I got error XCBUtil.PropertyListConversionError error 2.). It happened for combination INFOPLIST_OTHER_PREPROCESSOR_FLAGS = -traditional and INFOPLIST_PREFIX_HEADER which contained comments started with //. So I fixed it by changing comments to old style: /* */
