Create and import swift framework

Question

I\'m new in swift programming. I need to create pure swift framework and import it in my existing pure swift project. When I try to import swift framework, I\'m getting this

Answer 1

In Xcode 7.2 using Swift 2.1 I managed to get past the mentioned error by making sure that the build settings of your pure Swift framework called Foo are as follows:

1) Build Settings->Packaging->Defines Module = Yes

2) Build Settings->Swift Compiler - Code Generation->Install Objective-C Compatibility Header = Yes (if you do not need to import your Swift framework into Objective C set this setting to No)

3) Erase the string value of Build Settings->Swift Compiler - Code Generation->Objective-C Bridging Header

4)Build Settings->Swift Compiler - Code Generation->Objective-C Generated Interface Header Name = Foo-Swift.h (if you do not need to import your Swift framework into Objective C erase this setting as you did in step 3))

5) Make sure that Build Settings->Packaging->Product Name = Foo

6) Add to the public umbrella header of your framework (Foo.h), which you can use to import your Swift code to Objective C, the following line:

#import "Foo-Swift.h"

(but if you do not need to import your Swift code into objective C skip this step)

6) Add the following line to the Swift file where you want to use the module Foo:

import Foo

Important notes:

1) Ensure that your umbrella header Foo.h is set to public in the File Inspector, otherwise this won't work.

2) If you are using your pure Swift framework in Objective C files, ensure that:

• the Foo-Swift.h header has generated the correct interface by going to Foo.h and then clicking on the top left corner menu of the Xcode code editor and then choosing Includes->Foo-Swift.h (I had to rebuild the Foo framework a few times until Xcode caught-up with the change and then generated the correct interface in Objective C, so you may need to do that as well)

• your swift classes inherit from NSObject or they won't be available to Objective C code
