With the latest update to iOS 13, Apple introduced changes to push token data, location permissions, and Bluetooth settings. In response, Leanplum has made changes to our SDK and for this to continue to work, you will need to update to the latest version of our SDK. Below are the changes you will see in each area.
By default, Leanplum's iOS SDK uses method swizzling to collect push tokens. If your iOS app has multiple different SDKs installed that attempt to swizzle the push methods, it can cause problems where some push notification methods are not called.
