It looks like you skipped step 9 from the configuration process:

aleksandr-vdovichenko · February 6, 2016, 7:56pm

No, I didn’t skip this.

I have ssetuped this
2$(inherited) - non recursive$(PROJECT_DIR)/lib - recursive

mark-piller · February 6, 2016, 8:01pm

Is the “lib” folder for the Backendless libraries in blue or yellow color in Project Structure?

aleksandr-vdovichenko · February 6, 2016, 8:02pm

yellow

mark-piller · February 6, 2016, 8:07pm

Does it work if you use our bridging header?

aleksandr-vdovichenko · February 6, 2016, 8:13pm

It doesn’t work

aleksandr-vdovichenko · February 6, 2016, 8:15pm

And I removed Backendless.a and MediaLibiOS.a. Bacause I have 21 error

mark-piller · February 6, 2016, 8:19pm

Without backendless.a you will not be able to compile any code that uses Backendless API.

Can you create a new project and go through the getting started guide?

aleksandr-vdovichenko · February 6, 2016, 8:21pm

Okay, if I add backendless.a I have this

Hi Alex,

I prepare the “empty” project for you - https://drive.google.com/open?id=0B3yyaWhA4ib0R0ExQ3o4VTdjUTQ, it works fine for me, please try it and compare with you project.

Another way is to send your project for investigation, my email is slavav@themidnightcoders.com

Regards,
Slava

mark-piller · February 7, 2016, 4:33pm

Hi Alex,

Did Slava’s project template work for you? Were you able to find the differences between your project and the template?

Mark

aleksandr-vdovichenko · February 10, 2016, 11:33am

Hello guys! Your project works fine. Thanks

But when I try install my pod file:

source ‘https://github.com/CocoaPods/Specs.git’
use_frameworks!
pod ‘PermissionScope’
pod ‘pop’, ‘~> 1.0’
pod ‘EAIntroView’
pod ‘Google/Analytics’

I have this error :

aleksandr-vdovichenko · February 10, 2016, 11:50am

I have sent project on slavav@themidnightcoders.com

Thanks

Make the following:

Add lib folder from Backendless SDK (https://github.com/Backendless/ios-SDK/tree/master/SDK/lib) - with *.a files
Add AVFoundation.framework and CoreMedia.framework in “Build Phases -> Link Binary With Libraries”
Add
#import “Backendless.h”
#import “MediaService”
to your Bridging-Header.h file
