The following are some useful bits and pieces for working with Xcode.
iOS Simulator Laggy
With the release of Mavericks the OS had a featue called coalesing added. This is supposed to help in running iOS 6.1 and earlier. According to the Apple release NOTE:
Performance issues can arise when running apps within the iOS Simulator on OS X Mavericks with a simulated OS version of iOS 6.1 or earlier. A workaround is to disable timer coalescing while using the iOS 6.1 or earlier simulator by executing the following command in a Terminal window:
sudo sysctl -w kern.timer.coalescing_enabled=0
Target Simulator or Device for iOS
#if TARGET_IPHONE_SIMULATOR NSString *hello = @"Hey, I'm the iOS Simulator!"; #else NSString *hello = @"Hey, I'm an iOS device!"; #endif
Can’t locate header files for static iOS library
