    <p>Every <em>once in a while</em>, usually after I've done some <strong>trial and error</strong> on my code, Xcode <strong>throws random errors at me</strong> even though I've removed the previous incorrect code snippets, and even though I've restored my files to a stage where it last worked perfectly. In other words, <strong>there are no errors</strong> for sure, <strong>yet my app crashes and Xcode generates errors</strong>. I shall also add that when my iPhone isn't connected to my computer, the app runs just fine.</p> <p>After having <strong>removed everything that did cause errors</strong> in the past, Xcode - as described above - instead points to random stuff as being incorrect such as closing brackets, viewDidLoad, <strong>as if saying:</strong> <em>"Hey, I know there was an error before, can't find it now though but I know it's there somewhere so lets crash and point at something completely random such as a closing bracket"</em>.</p> <p>I assume the <strong>old project files are being cached</strong> (or similar) somewhere but I can't for the life of me figure out where or how to get rid of them. I'm using <strong>Xcode 4.5.2</strong>, <strong>iPhone 5 iOS 6.0.2</strong>, <strong>OSX 10.8.2</strong> fwiw.</p> <h2>What I've tried so far:</h2> <ol> <li>Clean, build, run, clean, rebuild, re-run. <strong>[no change]</strong></li> <li>Restart X-code, remove icon from home screen, step 1 again <strong>[no change]</strong></li> <li>Restart computer <strong>[no change]</strong></li> <li>Restart iPhone and simulator and reset simulator to factory settings <strong>[no change]</strong></li> <li>Delete the Derived Data from organizer as shown <a href="http://developer.apple.com/library/mac/#recipes/xcode_help-projects_organizer/articles/about_projects_organizer.html" rel="nofollow noreferrer">here</a>, and suggested <a href="https://stackoverflow.com/questions/12664937/xcode-highlighting-random-lines-and-calling-errors-when-there-isnt-any">here</a> <strong>[no change]</strong></li> <li>All above including restoring my entire iPhone <strong>[Works]</strong></li> <li>Create a new project and rebuild the nib file and copy past code from old project to new <strong>[Works]</strong></li> </ol> <p>Yes, <strong>alternative 6 and 7 do work</strong> but I can't spend hours on restoring my iPhone to factory settings or recreate my entire Xcode project every time this happens. Alas, it does happen quite often these days.</p> <p>Any other <strong>ideas or suggestions?</strong></p>

    1. COTry deleting the contents of ~/Library/Caches. Do you have time machine? Try rolling back to the last save.

    2. COThanks for your answer. Deleting the conents of Caches did not solve it either and unfortunately, I'm not using time machine. Any other suggestions?

    3. COAt a last ditch effort, one time I had to delete the contents of ~/Library/Saved Application State/com.apple.dt.Xcode.savedState. This worked for me on a similar error once. Otherwise I would try removing Xcode and reinstalling it.

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.
