UIPicker displaying ? instead of text

I'm still new to iOS coding but am trying to get my UIPicker to display the options I want, and then be able to take the option selected and do something with it. But rather than having the picker show my options it's just showing ? marks instead of my options.

Here's my GuardCompany.h

#import <UIKit/UIKit.h>
#define COLOUR 0 

@interface GuardCompany : UIViewController

<UIPickerViewDataSource,UIPickerViewDelegate>{

    IBOutlet UIPickerView *ColourAndShadePicker;

    NSMutableArray *arrayColour;
     }


@end

And here's my GuardCompany.m

#import "GuardCompany.h"

@interface GuardCompany ()

@end

@implementation GuardCompany

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)thePickerView {
    return 1;
}

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {

    if (component == COLOUR)
        return [arrayColour count];

    return 0;

}

- (NSString *)GuardCompany:(UIPickerView *)thePickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {

    if (component == COLOUR)
        return [arrayColour objectAtIndex:row];

    return 0;
}

#pragma mark - view lifecycle

-(void)viewDidLoad
{
    [super viewDidLoad];

    arrayColour = [[NSMutableArray alloc] init];
    [arrayColour addObject:@"red"];
}

@end

At first glance this looks incorrect:

- (NSString *)GuardCompany:(UIPickerView *)thePickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component

Change it to:

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
