This section assumes you've followed our Quickstart section of our Getting Started guide to install and configure our SDK.

Debugging

RevenueCat's SDK will log important information and errors to help you understand what is going on behind the scenes. You can enable more detailed debug logs with the debugLogsEnabled flag. You can set this immediately in your app while testing, before you configure Purchases.

Purchases.logLevel = .debug
Purchases.configure(withAPIKey: <public_sdk_key>, appUserID: <my_app_user_id>)

RCPurchases.logLevel = RCLogLevelDebug;
[RCPurchases configureWithAPIKey:@<public_sdk_key> appUserID:@<my_app_user_id>];

Purchases.debugLogsEnabled = true
Purchases.configure(PurchasesConfiguration.Builder(context, apiKey = "")
            .appUserID(<my_app_user_id>)
            .build()

Purchases.setDebugLogsEnabled(true);
Purchases.configure(new PurchasesConfiguration.Builder(context, <api_key>).appUserID(<my_app_user_id>).build());

Purchases.setDebugLogsEnabled(true);
Purchases.setup(<public_sdk_key>, <my_app_user_id>);

await Purchases.setDebugLogsEnabled(true);
PurchasesConfiguration pc = PurchasesConfiguration(<public_sdk_key>);
await Purchases.configure(pc);

Purchases.SetDebugLogsEnabled(true);

Purchases.setLogLevel(LOG_LEVEL.DEBUG);

OS_ACTIVITY_MODE and Common iOS Issues

On iOS, disabling OS_ACTIVITY_MODE in your Xcode scheme will block debug logs from printing in the console. If you have debug logs enabled, but don't see any output, go to Product -> Scheme -> Edit Scheme... in Xcode and uncheck the OS_ACTIVITY_MODE environment variable.

Flutter projects using Swift may fail to show debug logs in the console if you are using Visual Studio Code, Android Studio, or other IDE's to run your project. We recommend running your Flutter project using Xcode to view debug logs from the Purchases SDK.

Filtering Purchases Logs

All logs from the SDK are prepended with "[Purchases]", you can use this string as a filter in your log output to clearly see the logs that are from Purchases.
