Not able to get through Challenge Task 2 of 3. The code compiles successfully in Xcode though.

The code in Quote.h is as follows:

@interface Quote : NSObject { NSArray *_quotes; } // Add property here @property (nonatomic, readonly) NSArray *quotes;

  • (NSString *) randomQuote;

@end

The code in Quote.m is as follows:

import "Quote.h"

@implementation Quote

  • (NSArray *)quotes { if (_quotes == nil) { _quotes = @[@"1", @"2", @"3"]; } return _quotes; }

  • (NSString *) randomQuote {
    return @"Some Quote"; } @end

here is your issue:

@property (nonatomic, readonly)

that readonly attribute is whats causing the issue, make it strong instead:

@property (nonatomic, strong)

Thanks. For task 1, I tried @property (nonatomic) without strong (since objects are strong by default). It was consistently giving me errors, so the only other way I could make it work was by introducing readonly property (which wasn't needed as per the task and didn't make sense either). Thanks.
