Question

I have a file:

{
    "MapName" : "This is map1";
}

Which I try to read in with:

- (id)initFromFile:(NSString *)mapName
{
    self = [super init];
    if (self) {

        NSString* path = [[NSBundle mainBundle] pathForResource:mapName ofType:@"json"];
        NSData* jsonData = [NSData dataWithContentsOfFile:path];
        assert(jsonData);
        JSONDecoder* decoder = [[JSONDecoder alloc]
                                initWithParseOptions:JKParseOptionNone];
        assert(decoder);

        NSDictionary* json = (NSDictionary*)[decoder objectWithData:jsonData];

        assert(json);

        NSString* mapName = (NSString*)[json objectForKey:@"MapName"];

        assert(mapName);

        printf("MapName: %s\n", [mapName UTF8String]);
    }

    return self;
}

Which fails at assert(json);
Is there anything obvious i’m doing wrong?

I know the file is being read ok but the decode is passing back NULL.

Thanks

use comma instead of semicolon

{
    "MapName" : "This is map1",
}
