Creating Imports

Introduction

When you start using a class that is not yet imported, or a method from a library that is not yet included, AppCode will suggest to add the corresponding import automatically, or even add the import when you complete code.

The import statement is added to the imports section, but the cursor does not move from the current position, and your current editing session does not suspend. This feature is known as the Import Assistant.

The same possibility applies to the XML files. When you type a tag with an unbound namespace, import assistant suggests to create a namespace and offers a list of appropriate choices.

Importing missing header files

If you know that a class or function exists in your project or in a standard C/C++/Objective-C library, use it in your code.

To import a header file, follow these steps:

1. Type a reference to a non-imported class or function.
2. Press ⌥⏎. If there are multiple choices, select the desired import from the list.

   

Importing TypeScript symbols

In the TypeScript context, AppCode can generate import statements for modules, classes, and any other symbol that can be exported and called as a type. Open the desired file in the editor and do one of the following:

• Start typing the short name of a symbol. From the suggested variants for completion, select the relevant symbol name:

  

• Position the cursor at the unresolved symbol, which is displayed in red, and press ⌥⏎:

  

  On the context menu, select Add import statement and press ⏎.
• Configure AppCode to show a pop-up every time you hover the mouse pointer over an unresolved reference which required import:
  1. Open the AppCode Preferences by choosing AppCode | Preferences. Expand the Editor node, and then click Auto Import under General.
  2. On the Auto Import page that opens, select the Show import pop-up check box in the TypeScript area.

  Every time you hover the mouse pointer over an unresolved symbol, AppCode will display the following pop-up message:

  

  Press ⌥⏎ to have an import statement generated and inserted automatically.

In either case, AppCode inserts an import statement:

Importing an XML namespace

To import an XML namespace, follow these steps:

1. Open the desired file for editing, and start typing a tag. If a namespace is not bound, the following prompt appears:

   

2. Press ⌥⏎. If there are multiple choices, select the desired namespace from the list.
