![]() CODE SNIPPET SAVER HOW TOWith "Behaviors", you can tell Xcode how to react when certain events happen. Named tabs can then be used in "Behaviors" (see below). This makes it worth while to take some time to configure your "perfect" setup.Ĭ) By pressing "CMD + Opt + Shift + T" or clicking "Window > Rename Tab…" in the main menu, you can assign it a name. When opening the project again, Xcode restores the tabs - including their unique structure. Thereby, you can configure tabs that are optimized for different use cases (like coding, debugging, interface builder tasks. For example, one tab could contain just two editor panes, while another one could contain the project navigator, a single editor pane, and the utilities area. However, two things make tabs in Xcode especially powerful:Ī) You can configure each tab individually. Tabs are well-known from almost every IDE and text editor. CODE SNIPPET SAVER CODERead more about custom code snippets in Apple's documentation. You can search, edit and delete snippets in the library dialog that can be opened via Cmd + Shift + L. You can also define the scope in which the snippet is offered in the autocomplete window, e.g. Then highlight code in the editor, right-click on the selection and select "Create Code Snippet" from the context menu.īesides from naming it, you should also define a "Completion Shortcut": when you type these letters later, Xcode will offer to substitute them with your custom snippet. To do that, write a piece of code and remember to insert placeholders for values you have to fill out when invoking the snippet (e.g. Whenever you find yourself typing the same bits of code multiple times, you should create a code snippet. This popover gives you access to actions like showing quick help, jumping to the callers of a method, the definition of a type or variable and refactoring actions like "Extract to Method". Last but not least, you can show an "Action" popover for the code under the caret by pressing Cmd + Shift + A. In the case of Swift source files, this will open a generated file that contains just the interface. Xcode also makes it easy to open associated files by pressing Cmd + Ctrl + Arrow Up/Down. No need to scroll around the source file or scan the mini map. ![]() Selecting a method from this menu jumps to its position in the source file. ![]() If you opened a file with the "Open Quickly" dialog and want to jump to its location in the navigator pane, you can press CMD + Shift + J to do so.Īnother handy shortcut when editing or reviewing source files is Ctrl + 6 which opens a menu in the navigation bar that contains all classes, properties and methods of the current source file and allows filtering by just typing away. Simply start typing any part of the file's name - it doesn't even have to be consecutive letters: "mwinco" will find your " Main Window Controller" class.Īs if this wouldn't be cool enough, this dialog also lets you decide which editor to open the file in: hold down CMD + OPT + SHIFT while double-clicking the file to open. Instead, you can use Xcode's "Open Quickly" dialog (CMD + SHIFT + O). You shouldn't waste your time digging for a file in your folder hierarchy. You can also move the cursor to the edge of the window to open the file in a new editor there. The first visible editor will be highlighted and you can move that selection by moving the mouse cursor over another open editor to open the file there. When clicking on a file in the Navigator, hold down SHIFT + OPT.In Xcode, you can open a file in various ways: in the standard editor, in a new or existing assistant editor, in a new or existing tab, or in a new window. ![]()
