iOS Question Create Swift based Library

[JanPRO]

Hi,

is it possible to create a library based on swift sources, for example: https://github.com/danielgindi/Charts

When I try to use the above project I get hundreds of errors ...

On the one hand it is says in the project description, that it

can be used in both Swift and ObjC project.

but on the other hand I have read that it's not possible: http://stackoverflow.com/questions/29676470/static-library-and-swift

Any idea?

It will work if you can compile it as a framework.

Hi,

I can compile it as framework, but when I want to use the b4i library, the app crashes with the following error:

dyld: Library not loaded: @rpath/Charts.framework/Charts
Referenced from: /Users/............/B4iProject.app/B4iProject
Reason: image not found

The header file contains this attribute: //~DependsOn:Charts.framework.3

Any idea?

Have you copied Charts.framework to the Libs folder on the Mac?

 

[JanPRO]

Yes. The compilation process works fine, the error is thrown when I start the App.
By the way: On the project page it is said, that the framework should be used as an embedded framework.

Can you upload the framework?

 

[JanPRO]

Sure: https://drive.google.com/open?id=0B4XRpXYvS3nXYmJDbGJnNzZsNDA

Try this:
- Compile the project with B4i and let it fail (preferably in release mode when connected to the simulator).
- Open the project on the Mac with Xcode. Search the build settings for "Embedded Content Contains Swift Code" and set it to true.

Try to run it from Xcode. Does it work?

 

[JanPRO]

Embedded Content Contains Swift Code has been deprecated with XCode 8.

 

[Erel]

Set "Always Embed Swift Standard Libraries" instead.

 

[JanPRO]

Same error

 

[JanPRO]

Ok, i think I know whats' the problem: The library must be added to the "Embedded Binaries".
The steps I have made, to get the B4i project working:

1. Set "Always Embed Swift Standard Libraries" to YES
2. Remove Charts.framework from the Linked Frameworks section
3. Add Charts.framework to the Embedded Binaries

Would be greate if you can tell me if this is possible with the
- current B4iBuilder
- or you have to update the builder
- or if it's impossible

It should be possible. However it will not make it into B4i v3.50.

 

[Erel]

A beta with support for Swift libraries will be released next week...

Hi,

Yes. However my time is currently very limited, I will try to wrap it on weekend.
