Xcode "Parse issue", "Unexpected type" in @protocol declaration

Question

I recently added InAppSettingsKit to a project (although I don't think this is IASK specific).

I'm using Xcode 4.2 and it is giving a strange error:

 /Users/Username/Documents/ProjectName/a-branch/app-name/Code/InAppSettingsKit/Models/IASKSettingsStore.h:22:18: error: expected a type [1]
  - (void)setBool:(BOOL)value forKey:(NSString*)key;
                   ^ 1 error generated.

If I comment out the line it will build ok.

I've tried all the usual Xcode tricks, clean, restart, delete derived data folder etc.

The project is almost 750k loc and this is the first error of this type. — Richard Stelling, Dec 12 '11 at 11:27
I wasn't able to reproduce this in Xcode 4.2.1 with the current IASK source (revision 5fd23fd), and at any rate, that code is valid. If this was a bug in Xcode or the compiler you're using, it seems to have been fixed. — Peter Hosey, Dec 12 '11 at 14:59

This works but I still like to understand the error more:

Move the - (void)setBool:(BOOL)value forKey:(NSString*)key; line to the bottom.

@protocol IASKSettingsStore <NSObject>
@required
- (void)setBool:(BOOL)value forKey:(NSString*)key;
- (void)setFloat:(float)value    forKey:(NSString*)key;
- (void)setDouble:(double)value  forKey:(NSString*)key;
- (void)setInteger:(int)value    forKey:(NSString*)key;
- (void)setObject:(id)value      forKey:(NSString*)key;
- (BOOL)boolForKey:(NSString*)key;
- (float)floatForKey:(NSString*)key;
- (double)doubleForKey:(NSString*)key;
- (int)integerForKey:(NSString*)key;
- (id)objectForKey:(NSString*)key;
- (BOOL)synchronize; // Write settings to a permanant storage. Returns YES on success, NO otherwise
@end

This compiles (????)

@protocol IASKSettingsStore <NSObject>
@required
- (void)setFloat:(float)value    forKey:(NSString*)key;
- (void)setDouble:(double)value  forKey:(NSString*)key;
- (void)setInteger:(int)value    forKey:(NSString*)key;
- (void)setObject:(id)value      forKey:(NSString*)key;
- (BOOL)boolForKey:(NSString*)key;
- (float)floatForKey:(NSString*)key;
- (double)doubleForKey:(NSString*)key;
- (int)integerForKey:(NSString*)key;
- (id)objectForKey:(NSString*)key;
- (BOOL)synchronize; // Write settings to a permanant storage. Returns YES on success, NO otherwise
- (void)setBool:(BOOL)value forKey:(NSString*)key;
@end
