    <p>I have been working on an app all day which has been working fine until Xcode downloaded libraries or something and then it started having issues. I am just trying to create the getter/setter methods to get a couple of arrays out of my APPDelegate. Like I said it was working fine and then randomly it showed up with this error and now won't build anymore: </p> <pre><code>property with 'retain(or strong)' attribute must be of object type </code></pre> <p>Here is the rest of the code:</p> <pre><code>#import &lt;Foundation/Foundation.h&gt; #import "Project.h" #import "TeamMember.h" @interface Task : NSObject{ NSDate *endDate; NSDate *startDate; NSMutableString* notes; NSMutableString* taskName; //The error appears first right here over teamMember TeamMember *teamMember; Project *project; } //The error appears over both of the following lines as well... @property (nonatomic, retain)TeamMember *teamMember; @property (nonatomic, retain) Project * project; @property (nonatomic, retain) NSMutableString *notes; @property (nonatomic, retain) NSMutableString *taskName; @property (nonatomic, retain) NSDate *startDate; @property (nonatomic, retain) NSDate *endDate; @end </code></pre> <p>Any ideas? This has got me stumped....</p> <p>Here is Project.h:</p> <pre><code>#import &lt;Foundation/Foundation.h&gt; #import "Task.h" @interface Project : NSObject{ NSDate *dueDate; NSDate *startDate; NSArray *tasksInProject; NSMutableString* notes; NSMutableString* description; NSMutableString* projectName; } @property (nonatomic, retain) NSDate *startDate; @property (nonatomic, retain) NSDate *dueDate; @property (nonatomic, retain) NSArray *tasksInProject; @property (nonatomic, retain) NSMutableString *description; @property (nonatomic, retain) NSMutableString *projectName; @end </code></pre> <p>Here is TeamMember.h</p> <pre><code>#import &lt;Foundation/Foundation.h&gt; #import "Task.h" #import "Project.h" @interface TeamMember : NSObject{ NSMutableArray *projects; NSMutableString *name; NSMutableString *title; NSMutableString *email; NSMutableString *phone; NSMutableString *notes; } //@property(nonatomic, retain) NSArray *projects; @property (nonatomic, retain) NSMutableString *name; @property (nonatomic, retain) NSMutableString *title; @property (nonatomic, retain) NSMutableString *email; @property (nonatomic, retain) NSMutableString *phone; @property (nonatomic, retain) NSMutableString *notes; @end </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
