All SDKs

Make sure that you're using the latest version of the Unflow SDK, and have installed the SDK according to our guides. We update our SDKs very often. If you run into an issue with our SDK, it might already have been fixed in an update.

You can find the latest version of our SDKs here:



Issues when compiling or archiving

iOS

  1. Clean derived data: in Xcode, go to Product -> Clean Build Data.
  2. Make sure Swift support is enabled in the project: Check that Swift Language Version is defined as at least "Swift 5" in Build Settings for your target.

  3. Make sure that the deployment target is set correctly: it should be set to 11.0 or newer.



If you're using CocoaPods:

  1. Make sure you're using the latest version of CocoaPods. You can see your version by running pod --version, and find the latest version here.
  2. Re-install pods: run pod deintegrate and then pod install, then try running / archiving the project again.
  3. Make sure that the deployment target is set correctly: it should be set to 11.0 or newer. The requirements might be higher if you're using other frameworks, such as React Native. You should check this value both in the Podfile, and by going into the Project settings, then select the target, and look for the value in the general tab.
  4. Check the Swift version: Check that the value for SWIFT_VERSION isn't overridden by the Podfile.
  5. Enable Swift support: If you're getting errors when compiling Swift files after this, try adding a single, empty Swift file to the project.



Android

  1. Make sure your app meets the Minimum Requirements for the minimumSdkVersion and compileSdkVersion
  2. Ensure the activity in your manifest file has the android:exported flag set to true



React Native

  1. Upgrade to the latest version of unflow-react-native
  2. Upgrade to the latest version of React Native
  3. Follow the troubleshooting steps for iOS



If you receive an error when trying to run pod install that says `The Swift pod unflow-react-native depends upon React-Core, which does not define modules` it means that your version of React Native did not natively support Swift. There are two resolutions:

  1. You can upgrade to a version of React Native >=0.63.4
  2. Add pod 'React-Core', :path => '../node_modules/react-native/', :modular_headers => true to your Podfile
