Vistashow to prevent UITextfield from changing alignment when input language is RTL/Arabic?
The app language is English, the illustration on the left shows UITextfields content aligned to the left.. which is normal, but when the user selects an RTL/Arabic input language, the fields alignment are flipped automatically, how to force the alignment to be left disregarding the input language direction?
EDIT :
I tried this, and it's not solving the problem
let _beginningOfDocument = fieldPassword!.beginningOfDocument
let _endOfDocument = fieldPassword!.endOfDocument
fieldPassword!.setBaseWritingDirection(.leftToRight, for: fieldPassword!.textRange(from: _beginningOfDocument , to: _endOfDocument )! )

To be honest I tried all of them and doesn't work for me because it's related to the view hierarchy . For more information, you can read this note
Note iOS applies appearance changes when a view enters a window, it doesn’t change the appearance of a view that’s already in a window. To change the appearance of a view that’s currently in a window, remove the view from the view hierarchy and then put it back.
So try this one, it worked for me:
extension UITextField {
open override func awakeFromNib() {
super.awakeFromNib()
if Utilities.getCurrentLanguage() == "ar" {
if textAlignment == .natural {
self.textAlignment = .right
}
}
}
}
By the way, "Utilities.getCurrentLanguage()" is a function to get the current language.

It came out that some library I was using caused this effect, it's MOLH library, it uses method swizzling, this is why this was difficult to debug...
I will be making a pull request to it soon to make this effect optional...
func listenToKeyboard() {
NotificationCenter.default.removeObserver(self, name: UITextInputMode.currentInputModeDidChangeNotification, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(inputModeDidChange), name: UITextInputMode.currentInputModeDidChangeNotification, object: nil)
}
@objc func inputModeDidChange(_ notification: Notification) {
if let language = self.textInputMode?.primaryLanguage, MOLHLanguage.isRTLLanguage(language: language) {
self.textAlignment = .right
} else {
self.textAlignment = .left
}
}
Thanks.

In Swift 4
textField.semanticContentAttribute = UISemanticContentAttribute.forceLeftToRight
