+### Building Issues
+
+##### `'value'` is unavailable: introduced in iOS 12.0
+If you got the error `'value' is unavailable: introduced in iOS 12.0` when trying to build the app, you can follow the below steps to fix that:
+
+1. In your Xcode project navigator, select `Pods`
+2. Under Targets, select `React-Codegen`
+3. Set the window to `Build Settings`
+4. Under `Deployment`, set `iOS Deployment Target` to `12.4`
+5. Clean project and rebuild: `Product > Clean Build Folder, Product > Build`
+

+
+##### Dependency `'androidx.browser:browser:1.6.0-beta01'` requires libraries and applications that depend on it to compile against version 34 or later of the Android APIs.
+
+The solution is add `androidXBrowser = "1.4.0"` in your project.
+
+
+```java
+// android/build.gradle
+buildscript {
+    ...
+    ext {
+        // ...
+        androidXBrowser = "1.4.0"
+        // ....
+    }
+    ...
+}
+```
+
+##### Duplicate class kotlin.collections.jdk8.CollectionsJDK8Kt found in modules jetified-kotlin-stdlib-1.8.10 (org.jetbrains.kotlin:kotlin-stdlib:1.8.10) and jetified-kotlin-stdlib-jdk8-1.7.22 (org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.7.22)
+
+The solution is add `org.jetbrains.kotlin:kotlin-bom:1.8.0` dependency in your project.
+```java
+// android/app/build.grade
+dependencies {
+    ...
+    implementation(platform("org.jetbrains.kotlin:kotlin-bom:1.8.0"))
+    ...
+}
+```
+### Caching Issues
 
 Sometimes there will be issues related to caching when you develop React Native.
 There are some recommendations for cleaning the cache:
