iOS15 and android 12 on React Native


iOS 15 Major Changes - 

Following are the same major changes which we can see after updating the app.

  1. QuickType Bar:  I think you all know about the Quicktype Bar, if you use the text input then you must know about it if not then I told you, quicktype bar is a bar which is above the keyboard, here you see the 3 - words matching with your typed word. So the change is if you want to hide the quick bar then you need to set the false for autoCorrect and spellCheck.

Note - To disable the QuickType bar in iOS 15, set prop spellCheck and autoCorrect to false.

Syntax - <TextInput  





  1.  Transparent Navigation Bar: In iOS 15 you see the change in the navigation bar as we know iOS 14 has the transparent navigation bar when we scrolled up the app.

Simulator Testing - For testing your app with iOS 15, you need to download and install the Xcode 13.

Android 12 Major Changes - 

Android 12 introduces some changes which surely affected your app experience, following are some changes.

  1.  Overscroll Effect: It affects the overall scroll view containers, as we know that react native scroll views are based on native scroll so you can check to see if it is working correctly or not.
  2. Permission Updates: Android 12 updates the permission as well, ACCESS_FINE_LOCATION only provides the approximate location if you request for it.
  3. Restrictive App Standby bucket: In Android 12 it introduces the new bucket with the name of restricted. It has the lowest priority and the order is from high to low.
    1. Active
    2. Working set
    3. Frequent
    4. Rare
    5. Restricted
  4. Power management restrictions: Here you find where your app is placed in a restricted bucket. 
  5. Graphics and images: In Android 12 we check the refresh rate changes using setRateFrames. It shows the seamless transition of behavior. It is called the refresh rate switch.
  6. Security and privacy: On Android 12 it allows the supported devices, users can anytime enable and disable the microphone and camera for any app or device. Users can access the toggle by single clicks. 

    1. Check whether a given device supports a microphone and camera toggle.

    2. Check the response in-app behavior to microphone and camera toggles.
