Xcode behaviors can change the way how Xcode responds to certain events. Default behaviors help you already by showing, for example, the debug navigator when hitting a breakpoint, but they can speed you up a lot more.
A list of behaviors which are not enabled by default. The starting point is the behaviors tab which can be found in Xcode preferences which can be opened by
cmd + , or using the
Xcode -> Preferences menu.
Open the Issue Navigator for build failures
Surprisingly, but true. The issue navigator by default does not open when a build fails. The result of this is that you navigate to the issue navigator yourself to see what is wrong. By navigating to the current log you can even quickly filter on errors only to see what is wrong.
Open the Test Navigator for test failures
When a test fails, you want to navigate to that test and run it again when you’ve fixed it. The starting point for navigating to the failing test is the Test Navigator.
Start debugging in a new tab
You’re writing your code and running your app to test your feature. A breakpoint or issue appears and you’re suddenly in a different file which is not always what you were waiting for.
By opening a new tab when your running app pauses you can simply finish your debug session and return to your working file by closing the tab.
You can do exactly the same for when your app pauses for tests.
