iOS Braintree Dropin ui, throws undeclared identifier 'BTAppSwitch`

Question

I am using the Braintree drop-in ui for React Native. My issue seems maybe not specific to the library, in which I have already created an issue.

I'm at the point where I need to add my setReturnURLScheme to my AppDelegate.m

Looks like this

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  [BTAppSwitch setReturnURLScheme:@"com.mycompany.myapp.payments"];
  //...
}

However, I receive an error with BTAppSwitch, it says Use of undeclared identifier 'BTAppSwitch'.

As far as I can tell, I have installed and linked all pods appropriately/automatically, but most instructions are pretty brief. Seems like maybe I'm missing an import statement, but none I've tried have helped. Can someone help please?

I am using v4

You need to import the following in your AppDelegate.m file

#import "BraintreeCore.h"

Make sure you've used the correct bundle identifier as follows

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  [BTAppSwitch setReturnURLScheme:@"yourappbundleidentifier.payments"];
  return YES;
}

and your info.plist must includes this

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleTypeRole</key>
        <string>Editor</string>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>yourappbundleidentifier.payments</string>
        </array>
    </dict>
</array>

In case you're still facing the issue while archiving the app in xcode. Make sure

#import "BraintreeCore.h"

must be placed before this line of code

#ifdef FB_SONARKIT_ENABLED

Hope this will resolve your issues
