Objective-C Question

Hello, I am stuck on a problem here.

How can I make my objective-C work for this:

- (void) testThatIncrementsWork {
    NSInteger sourceNumber = 17;
    NSInteger resultNumber = [self.calculator increaseNumberBy1:sourceNumber];
    XCTAssertTrue(resultNumber == 18, @"17 + 1 = 18");

    sourceNumber = 972;
    resultNumber = [self.calculator increaseNumberBy1:sourceNumber];
    XCTAssertTrue(resultNumber == 973, @"972 + 1 = 973");
}

How can I make it work with this method here:

- (NSInteger) increaseNumberBy1:(NSInteger) number {
    /* WORK HERE */
    return number;
}
