+
+With Sentry Structured Logs, you can send text based log information from your applications to Sentry. Once in Sentry, these logs can be viewed alongside relevant errors, searched by text-string, or searched using their individual attributes.

+#### beforeSendLog
+
+To filter logs, or update them before they are sent to Sentry, you can use the `beforeSendLog` option.
+
+```swift {tabTitle:Swift}
+import Sentry
+
+SentrySDK.start { options in
+    options.dsn = "___PUBLIC_DSN___"
+    options.experimental.enableLogs = true
+
+    options.beforeSendLog = { log in
+        if log.level == .info {
+            // Filter out all info logs
+            return nil
+        }
+        return log
+    }
+}
+```
+
+```objc {tabTitle:Objective-C}
+@import Sentry;
+
+[SentrySDK startWithConfigureOptions:^(SentryOptions *options) {
+    options.dsn = @"___PUBLIC_DSN___";
+    options.experimental.enableLogs = YES;
+
+    options.beforeSendLog = ^SentryLog* (SentryLog *log) {
+        if (log.level == SentryStructuredLogLevelInfo) {
+            // Filter out all info logs
+            return nil;
+        }
+        return log;
+    };
+}];
+```
+
+The `beforeSendLog` function receives a log object, and should return the log object if you want it to be sent to Sentry, or `nil` if you want to discard it.
+
+The log object has the following properties:
+
+- `level`: The log level (trace, debug, info, warn, error, fatal)
+- `message`: The message to be logged
+- `timestamp`: The timestamp of the log
+- `attributes`: The attributes of the log

+Once the feature is enabled on the SDK and the SDK is initialized, you can send logs using the `Sentry.logger` APIs.
+
+The `Sentry.logger` namespace exposes six methods that you can use to log messages at different log levels: `trace`, `debug`, `info`, `warn`, `error`, and `fatal`. Supported types for attributes are Strings, Int, Double, and Bool.
+
+```swift {tabTitle:Swift}
+import Sentry
+
+let logger = SentrySDK.logger
+
+// Log messages without attributes
+logger.trace("Starting database connection")
+logger.debug("Cache miss for user")

+logger.debug("Cache miss for user", attributes: ["userId": 123])
+logger.info("Updated profile", attributes: ["profileId": 345])
+logger.warn("Rate limit reached for endpoint", attributes: [
+    "endpoint": "/api/results/",
+    "isEnterprise": false
+])
+logger.error("Failed to process payment", attributes: [
+    "orderId": "order_123",
+    "amount": 99.99
+])
+logger.fatal("Database connection pool exhausted", attributes: [
+    "database": "users",
+    "activeConnections": 100

+
+### String Interpolation (Swift Only)
+
+Swift supports automatic extraction of interpolated values as attributes. When you use string interpolation in your log messages, supported types (Strings, Int, Double, and Bool) are automatically extracted and added as attributes with the key format `sentry.message.parameter.{index}`.
+
+```swift
+let userId = "user_123"
+let orderCount = 5
+let isPremium = true
+let totalAmount = 99.99
+
+// String interpolation automatically extracts values as attributes
+logger.info("User \(userId) placed \(orderCount) orders, premium: \(isPremium), total: $\(totalAmount)")
+
+// This is equivalent to manually specifying attributes:
+let message = "User \(userId) placed \(orderCount) orders, premium: \(isPremium), total: $\(totalAmount)"
+logger.info(
+  message,
+  attributes: [
+      "sentry.message.template": "User {0} placed {1} orders, premium: {2}, total: {3}",
+      "sentry.message.parameter.0": userId,
+      "sentry.message.parameter.1": orderCount,
+      "sentry.message.parameter.2": isPremium,
+      "sentry.message.parameter.3": totalAmount
+  ]
+)
+```
