I’m quite new to swiftui and I was curious on what’s the difference between using a button displaying an image or an image with onTapGesture modifier that make an action just like the action on buttons.
In the use case you've described you can use either but for reference, Apple provides the following guidance in their documentation for onTapGesture:
If you are creating a control that’s functionally equivalent to a Button, use ButtonStyle to create a customized button instead.
onTapGesture adds an action to perform when the view recognizes a tap gesture and can be tailored to respond to any number of taps (with 1 being the default).
Buttons are a control that performs an action when triggered and have the benefit of automatically adapting their visual style to match the expected style within different containers and contexts.
In iOS and watchOS, the user triggers a standard button by tapping on it.
In macOS, the user triggers a standard button by clicking on it.
In tvOS, the user triggers a standard button by pressing “select” on an external remote, like the Siri Remote, while focusing on the button.
For more information please refer to Apples documentation here: https://developer.apple.com/documentation/swiftui/text/ontapgesture(count:perform:)

I would recommend using Button when you want the feature of a button. I noticed that images cannot be used as buttons with Voice Over on. When I changed those to use Button instead, it fixes the problem.
I'm new to iphone programming. there are lot of basic controls in xcode which i can implement but i want to know how to create the control shown below in iphone.
It is not present in list of control objects in xcode
There are no default dropdown implementations available for iPhone. You can try to implement a UIPickerView or UIActionSheet based on the requirement.
If you cannot modify your design, you can go ahead and implement your own dropdown implementation. Basically you need to have a button with the above image as background view and on tap of that you need to show a table view below that. Alternatively you can check this custom dropdown list and this Drop Down Demo iOS.
Xcode does not provide this control.You can create custom control with a table view and Button.Show the table view when you click on it and hide it on again clicking on it.You can also add images on background for the same look.
Is it possible using the SDK to change the bluetooth headset/remote buttons behavior. I would like to capture the button press(es) and perform some action, eg, skip next track, launch popup etc
I think you will receive appropriate callbacks from iOS when a button is pressed, and within these callbacks you can decide what to do.
How do I a use radio button in an iPhone app? Should I load any image instead of button image?
A fairly standard replacement for radio buttons on iOS is a "picker". An alternative, if you have a large number of potential choices, is to use a static list under a button, and allow only one of the items to be selected and checkmarked.
You can use a custom button & change its image on button click
Take a look at the UISegmentedControl. It functions basically as a radio button for up to ~4 options. There's no maximum limit AFAIK, but any more than 4 is somewhat difficult visually.
Try DLRadioButton, the best Radio Button control for iOS. It is highly customizable, you can also use you own image as selection indicator. It is available through Cocoapods pod 'DLRadioButton', '~> 1.4' and at GitHub.
Screenshot for your reference.
When I set the value 'true' to showCancel property in the method Titanium.UI.createSearchBar. It displays me the cancel button, but I would like to customize that button text to Go or anything else. How do I do that? Please give me suggestions. Thanks you so much.
I don't believe in Titanium Mobile SDK 1.4 you can change the button text.
As a work around you could add your own button to the screen and have it interact with the tableview. Not an ideal solution though.
Please find below the current documentation link.
