xcode4.5

I have recently downloaded Xcode update 4.5.2 and it seems to performing slow. I have tried other applications and everything is running fine. I'm currently developing an app and it's been performing so slowly, that I can't edit an UIlabel box.

I use NSOpenPanel on two occasions: When the user selects "Open" from the "File" menu (since it is a document-based application, none of my own code is involved) and for importing some data into my document (so it gets called by my own code). NSOpenPanel crashes on both occasions (the dialog opens, but before I can do anything, an exception is raised). I made clean, tried switching compiler from Apple

I making a social application which requires Google+. I know that I can open Google+ as a link to Safari (Which isn't really user Friendly having to switch apps just to post something). This code opens the link to Safari: -(IBAction)Google+:(id)sender { NSLog(@"Google+"); //The link will go to Stack Overflow Google+ Page NSURL *GooglePlus = [NSURL URLWithString:@"https://plus.google.com/+StackExchange/posts"]; [[UIApplication sharedApplication] openURL:GooglePlus]; } But is there a way to detect if Google+ Application is installed and open the application there (And if it isn't then open the

I thought I'd figured out how to store XCode projects in source control - I only version the .pbxproject file and this seems to work great. But then I noticed the provisioning profile is also kept there. This doesn't seem very good, I'm working remotely with another developer and we both have individual provisioning profiles. We keep committing new versions of the .pbxproject file with our own profile every time we change anything which is annoying, and I wonder if sharing such information is a security risk? Is there a way around this? Are we 'supposed' to be using the same team profile or
