Xcode 4.5.2 errors are found but Build is marked as Succeeded
Cleaning the product folder and restarting didn't help me. I started seeing this after I deleted the DerivedData folder. I was able to "fix" by doing :
- Clean build.
- Archive
- Build
I had this same issue, and neither types of cleans helped. I also tried deleting the build folder, restarting xcode, etc and for me what finally solved the issue was to remove the files that the errors referenced and re-add them.
Additionally, I investigated the error after the fact, and the issue seems to be XCode's "Show Live Issues" feature. (This can be unchecked in the preferences, this also solved the issue but was unsatisfactory as a solution as I've grown to enjoy xcode's live code sense.)
Have you tried cleaning the build folder?
In XCode, open the Product menu then hold down option. Clean should change to Clean Build Folder.
Edit:
You can also press ⌘ + ⌥ + ⇧ + K
Cleaning, closing, restarting - none worked for me.
A simple touch/edit to the pch file in question resolved the issue.
