I’m often in a situation where I have my storyboard open in XCode, then I open up the Assistant Editor to connect something from the storyboard, to my code, only to find the wrong file in the Assistant Editor!
Usually, I would go to the Assistant Editor, and manually go through the navigation system to find the file I need. But recently, I learned that I didn’t have a very important option in XCode turned on!
If you go to your XCode > Preferences > Navigation, select the Uses Focused Editor option. Now, you can search in your Assistant Editor just like in you would in your main editor (Command + Shift + O FTW!) as long as it’s focused!
Wish I knew about this earlier!
