Fix a simple code for Mac OS

READ CAREFULLY BEFORE BIDDING I have implemented a very simple iOS app with a custom "Tap Gesture". So after it's working successfully, I tried to make the same equivalent code "Click Gesture" for Mac OS, but I couldn't. - Project is attached: [login to view URL] The problem is only in the code when someone clicks on the NSTextView. The flashing insertion cursor doesn't show on the click location, instead, it's shown at the end of the text and not working properly. - Problem screen recording is attached: Problem [login to view URL] What I need: - Please download the project (use Xcode 12) and test the problem (You can comment out the code with errors, just to build the project and see the problem yourself). I need the simple custom click gesture that I made to behave normally when the user clicks the NSTextView. - Note that I need to use a custom click gesture. - Code is very basic and simple, but needs an expert in macOS and Cocoa. - Bids over $50 will not be accepted. - Do not bid unless you read and test the problem, and you're confident that you can do it.
