Troubleshooting Xcode is a handbook for software developers of all levels creating applications for iOS and OS X using both Objective-C and Swift.
If you’ve struggled in the past to make Xcode work as expected, to solve problems that defy logic, and to understand Xcode’s misleading or cryptic error messages and unexpected crashes, Troubleshooting Xcode is for you.
Troubleshooting Xcode is great for the developer wanting to extend his or her knowledge about obscure problems and limitations involving the use of Xcode, Objective-C, and Swift as well as how to use automation to increase productivity and make some repetitive tasks easier.
