Bug Report

XCode build fails: Redefinition of enumerator 'SYNTAX_ERR

Problem

The error started to appear when I added the below cordova plugins to the project where cordova-sqlite-storage plugin already existed:

• cordova-plugin-file
• cordova-plugin-qrscanner

What is expected to happen?

Build should not break.

What does actually happen?

Xcode build fails

Information

The cordova-sqlite-storage plugin has WebSQLError enum with SYNTAX_ERR = 5 and cordova-plugin-file plugin has CDVFileError enum with SYNTAX_ERR = 8. It seems to be the problem with the same name for these enums.

Command or Code

N/A

Linking to storesafe/cordova-sqlite-storage#868, which is marked as a bug. I would like to resolve this problem on the cordova-sqlite-storage side. (I will probably need a few weeks to look into this one.)

The SYNTAX_ERR enumerator seems to have been defined on both plugins for several years. So I find it pretty strange that this problem would suddenly appear after multiple years. I wonder if it has anything to do with an Xcode update or any other framework updates?

Lines 26 to 40 in 5e12b5e

	enum CDVFileError {
	NO_ERROR = 0,
	NOT_FOUND_ERR = 1,
	SECURITY_ERR = 2,
	ABORT_ERR = 3,
	NOT_READABLE_ERR = 4,
	ENCODING_ERR = 5,
	NO_MODIFICATION_ALLOWED_ERR = 6,
	INVALID_STATE_ERR = 7,
	SYNTAX_ERR = 8,
	INVALID_MODIFICATION_ERR = 9,
	QUOTA_EXCEEDED_ERR = 10,
	TYPE_MISMATCH_ERR = 11,
	PATH_EXISTS_ERR = 12
	};

I don't even know why this is clashing with yours...

I solved it by simply removing and adding the plugin again.

Some plugins, e.g. file-transfer and zip, will cause this problem. After installing those plugins, removing file plugin with
cordova plugin rm cordova-plugin-file --force and then add it with cordova plugin add cordova-plugin-file will fix the problem.
