As soon as I restarted simulator, it worked. Additional Efforts: Untick Connect Hardware keyboard Restart Simulator again. (right click simulator icon and Quit. Closing simulator alone would not help, may b.)

Yes, I am using history.pushState() for URL change and I already have shared my report via Feedback Assistant. It would be great if I will be able to solve this within current version.

I sent my feedback via Feedback Assistant.

I tried above changes still my message seems nearly same and it points for Credit card details, etc. As mentioning below, The extension “ABC” would like to access stackoverflow.com. This extension would be able to read and alter webpages and see your browsing history on this website. This could include sensitive information, including passwords, phone numbers, and credit cards. You can change this later in Safari Websites preferences. In my manifest.json, I have removed all permission but activeTab, still facing same privacy message. Is this default from Apple? It seems a bit scary as it states we have access to user's credit card details, etc.

Thanks for this. I get it.

Thanks for the tool and I am able to fully create a valid xcode project with this tool. Bingo! But if we take reference for SeaCreator, when we tap on the extension icon, it turns into blue to indicate the extension is active and whenever any page is rendered, all fish names will be automatically replaced with emojis. What I need is I want the replace action to be executed only when I explicitly press the extension button. So, whenever I open a new webpage I must have to explicitly press extension toolbar button only then replacement should be done. In the code I have attached, I did try few things but none help. //browser.runtime.addEventListener("message", handleMessage, false); //function handleMessage(msgEvent) { //		alert('message received'); 		var wordReplacementMap = {"Fish": "🐠", "Shark": "🦈", "Squid": "🦑", "Whale": "🐋"}; 		for (var wordToReplace in wordReplacementMap) { 				replace(document.body, wordToReplace, wordReplacementMap[wordToReplace]); 		} //} //chrome.runtime.sendMessage("message"); I am always facing -> undefined browser or undefined chrome. In my original extension project I have used node modules and AJAX also so there are lots of dependencies why I did took reference for Apple's example. The main thing is I want to turn off automatic script injection and only execute my script code when user taps on extension button. I don't need popup - just execution on tap of button. I have also posted Stackoverflow questions for this here -> https://stackoverflow.com/questions/62774734/safari-web-extension-injecting-script-only-when-extension-button-is-clicked I hope I have made my point clear. Please suggest me solution on this. Thanks.
