The easiest way to get the SDK into your iOS project is to use CocoaPods. Install CocoaPods using
gem install cocoapods
If this is your first time using CocoaPods, run
pod setup
to create a local CocoaPods spec mirror. Create a file in your Xcode project called Podfile and add the following line:
pod 'Ringcaptcha'
In your Xcode project directory run
pod install
to download and install the library. CocoaPods will create a new Xcode workspace. Remember to open up this workspace in Xcode and not your project.
To embed the SDK just drag & drop the iOS SDK library into your libs folder in your XCode project.
After adding it, make sure that in every target that the SDK will be included you link it to Ringcaptcha.framework and CoreTelephony.framework.
Also Include under your Project "Build Settings", "Linking" -> "Other Linker Flags" the following value: "-ObjC -all_load".
On each file you will be including RingCaptcha, make sure you import the header file.
Copy
**#import <Ringcaptcha/Ringcaptcha.h>**
