 <p>It seems that there are multiple reasons for "domain = LaunchServicesError code = 0" error. I also encountered it, while I try to reinstall app on iOS8 simulator. I cannot reinstall but have to delete the old app first.</p> <p>The problem was solved by:</p> <ol> <li><p>In Xcode, fill empty Version or Build field with appropriate value in your Target->General->Identity</p></li> <li><p>In Simulator, reset Content and settings... </p></li> </ol> <p>After that, everything works fine.</p>
