WELCOMEWelcome to the Apple Developer Forum for AppleScript. Here you can access and share information about OS X's popular native scripting language. On this page you will find links to resources for developers and scripters alike, including training materials and code examples. Enjoy!THE LANGUAGE OF AUTOMATIONAppleScript is an English-like language used to create script files and applets that control the actions of the computer and the applications that run on it. AppleScript scripts can “think” and make decisions based on user-interaction or by parsing and analyzing data, documents or situations. With support integrated into hundreds of Apple and third-party applications, AppleScript provides motivated customers an approachable way to address their specific automation requirements by writing their own scripts or using those developed by others.THE BENEFITS OF APPLESCRIPTResearch has shown that a primary requirement of customers, professionals, and businesses alike is for customizable automation to

There are a couple error messages that developers have seen when using the iOS Simulator. We can certainly do better to make these error messages less cryptic in future releases, but for now, hopefully this post will help you out. Note that this information (likely a more condensed form of it since I am quite verbose here) should appear in Xcode release notes.1) Unable to boot the iOS SimulatorThis error message will appear in iOS Simulator, and if hitting Build&Run from Xcode, you will likely get an (Domain = DTiPhoneSimulatorErrorDomain, Code = 2) error there as well. With iOS 7 and later, the simulator runtime gained its own bootstrap server (launchd_sim) rather than relying on the host's launchd. In Xcode 6.0 and 6.1, this error message is only displayed in the event that launchd_sim crashes upon launch before the simulator can checkin with it. The only known cause of this issue is from the installation of 3rd party software which alters the behavior of OS X in unsupported ways by setting DYL
