> This is reference counting code.
> Line:
> https://github.com/apache/cordova-ios/blob/5c3885b807f4c9556bf350c72400827a333f78d3/bin/templates/scripts/cordova/lib/plugman/pluginHandlers.js#L100
> {code}
> project.frameworks[src] -= (project.frameworks[src] || 1) - 1;
> {code}
> which expands to:
> {code}
> project.frameworks[src] = project.frameworks[src] - (project.frameworks[src]
> || 1) - 1;
> {code}
> project.frameworks[src] would contain a number, or undefined.
> My guess is that the intent of this line is to decrement the reference count
> by 1. If the count was not set, the resulting count value should be negative,
> according to the next conditional "if (project.frameworks[src] < 1) {" where
> it would delete the entry in the object.
> The correct line should be:
> {code}
> project.frameworks[src] = (project.frameworks[src] || 1) - 1;
> {code}
