PayPal integrated iOS 8 App - ios

Question

I have downloaded and played with the github project for the paypal ios app.
https://github.com/paypal/PayPal-iOS-SDK
I ran it just fine without any errors. When I try to link it into my iOS 8 swift project I can load all the files and connect the view controllers just fine and I believe my bridge header file is working just fine. I basically moved all the viewcontroller files from the sample app into my project and just connected what I needed to. I have the client id and secret id working I believe. It is when I try to create a FuturePaymentViewController :
- (IBAction)getUserAuthorizationForFuturePayments:(id)sender {
NSLog(#"\n\n\nbegin getting user authorization\n\n\nPAYPAL CONFIG:::: %#", self.payPalConfig);
PayPalFuturePaymentViewController *futurePaymentViewController = [[PayPalFuturePaymentViewController alloc] initWithConfiguration:self.payPalConfig delegate:self];
//breaks here when trying to send the config init.
NSLog(#"\n\n\nafter initializtion of paypal future payment view controller\n\n\n");
[self presentViewController:futurePaymentViewController animated:YES completion:nil];
NSLog(#"after present");
}
Error I get is :

This should not be breaking since no different from the sample project but I have no idea why it is. Please help me, thank you!

Answer 1

Dave from PayPal here.
I believe that your problem will be solved by step 3 of our integration instructions:
In your project's Build Settings (in the TARGETS section, not the PROJECTS section):
add -lc++ -ObjC to Other Linker Flags
Also, please note Step 1 of our sample code, which indicates that you must call [PayPalMobile initializeWithClientIdsForEnvironments:] to initialize the SDK, prior to calling other methods.
