Objective-C Bridge NSArray Crash

I'm trying to send some data from a swift file to an objective-c file. I have all the bridging headers and whatnot configured, such that when I pass a string, it can be used by the objective-c file. However, I would really like to pass an NSArray, and when I do this, I get a whole slew of errors starting with 

[Swift._NSSwiftArrayImpl length]: unrecognized selector sent to instance 0x6000000363a0

I saw Array element cannot be bridged to Objective-C but solutions on that page, which were switching the Array to an NSArray in swift, and making all the objects in the array AnyObjects, did not work; besides, the error I got is different from the error on the aforementioned question. This is my condensed code:

Swift:

var myNSArray = ["foo","bar"]
objectiveCClassInstance.arrayPassFunction(myNSArray)

.h:

- (void)arrayPassFunction:(NSArray*)myObjectiveCNSArray;

.m:

- (void)arrayPassFunction:(NSArray*)myObjectiveCNSArray{
    NSLog(myObjectiveCNSArray);
}

Your call to NSLog is incorrect. The first parameter of NSLog is the format string. You meant:

NSLog(@"%@", myObjectiveCNSArray);

I'm surprised you didn't get a warning about this.
