Instance Method


Sets the URL’s resource properties for a given set of keys to a given set of values.


func setResourceValues(_ keyedValues: [URLResourceKey : Any]) throws



A dictionary of resource values to be set.


The error that occurred if one or more resource values could not be set.

Return Value

true if all resource values in keyedValues are successfully set; otherwise, false.


This method synchronously writes the new resource value out to disk. If an error occurs after some resource properties have been successfully changed, the userInfo dictionary in the returned error object contains a kCFURLKeysOfUnsetValuesKey key whose value is an array of the resource values that were not successfully set.

Attempts to set a read-only resource property or to set a resource property that is not supported by the resource are ignored and are not considered errors.

The order in which the resource values are set is not defined. If you need to guarantee the order in which resource values are set, you should make multiple requests to this method or setResourceValue(_:forKey:).
