-*** IMPORTANT NOTES FOR IOS ***
-Image Picker will crash if you pick image for a second times, this error only exist on iOS Simulator 14 globaly around the world but not error on the real device
-If you want to use iOS Simulator, you need to downgrade and using iOS Simulator 13
-Follow this step to downgrade :
-1. Xcode > Preferences
-2. Select the "Components" tab.
-3. Download and select Simulator 13 after the download is finish
-4. Press "Check and Install Now".
-5. After that, use Simulator 13 instead of simulator 14
