Try to run the app, and if that doesnt work, you need to see if theres an error message that you can Google for more help.

You can save time by practicing these 14 Xcode Keyboard Shortcuts in your daily code.

My design friends from Brault Barnes put together a great PDF that looks amazing.

There are many keyboard shortcuts in Xcode that can make yourself a more efficient programmer.

They can help you quickly navigate around your code files to find and fix bugs, or to add new features to your apps.

When youre in the zone, you want to be able to access the code files quickly, or the adjust Xcodes panels to fit your small laptop screen.

The following keyboard shortcuts for Xcode are the best ones to learn first.

Project Navigator: Command 1 Quickly view all your code, images, and user interface files.

The happens a lot if you use the Assistant Editor (tuxedo) or when you design the user interface and connect it to code.

Instead of scrolling through hundreds of lines of code you can find all occurrences of a variable, or jump to a specific line of text.

Find Navigator (ie.

Search): Command Shift F Find all the times you mentioned a variable or method name with the project search.

You can match based on case, or ignore upper and lower case letters.

You can also replace all occurrences of a variable name with a new variable name.

If you have hundreds or thousands of lines of code, you can quickly narrow down where you need to insert code to support a new app feature.

It lets you just type and jump to a method definition or a specific code file.

Example, in ViewController.Swift press Command Shift O and then type vDL.

The first result will be the function with the name v iew D id L oad().

You can quickly switch between two related code files, like the header and implementation files in Objective-C using this Control Command Up Arrow shortcut.

If youre writing code in Swift, you wont need to worry about this shortcut, since Swift uses a single code file.

App Building and Cleanup To try out your new app you have to run it, and occasionally Xcode doesnt feel well, so you may have to clean it up.

These shortcuts will keep you writing code without stopping to use the mouse as much.

Run the app: Command R When I write code, I routinely use this command to make sure the app is running bug free.

The more often you test your app the better, since you can find and fix bugs early, before they become big problems.

When that happens youll first want to clean and then re-run the Xcode project.

If that still doesnt fix the problem, close Xcode and re-open it again.
